Chrysomelidae, the leaf beetles

Spotted Cucumber Beetle (Diabrotica undecimpunctata)
Spotted cucumber beetle Diabrotica undecimpunctata, subfamily Galerucinae, family Chrysomelidae.
□ True to its name of spotted cucumber beetle, this attractive beetle does love cucumbers, but it will also eat other crops, including melons and pumpkins. The adults dine on leaves, vines, and fruit.
Photographed by: Quy Thai. Identified by: KnowYourInsects.org. Location: Sterling Heights, Macomb County, Michigan, USA. Date: 31 August, 2014.
Spotted Cucumber Beetle (Diabrotica undecimpunctata)
Spotted cucumber beetle, Diabrotica undecimpunctata, subfamily Galerucinae, family Chrysomelidae.
□ The larva of the spotted cucumber beetle is sometimes called a southern corn rootworm because it bores into the stems of corn plants, usually right at ground level or a bit above, and this can kill the plant. More information about this species is available here.
Photographed by: Dave Delman, M.D. Identified by: KnowYourInsects.org. Location: New York Botanical Garden, Bronx, New York, USA. Date: 28 October, 2017.
Spotted Cucumber Beetle (Diabrotica undecimpunctata)
Spotted cucumber beetle, Diabrotica undecimpunctata, subfamily Galerucinae, family Chrysomelidae.
□ Some spotted cucumber beetles have a yellowish-green abdomen, as can be seen in this photo that shows the abdomen peeking out beyond the forewings (elytra). Others have a more yellowish-orange abdomen. Those with the yellowish-green abdomen fall into the subspecies Diabrotica undecimpunctata undecimpunctata; and the yellowish-orange ones in the subspecies Diabrotica undecimpunctata howardi.
Photographed and identified by: Thomas Langhans. See Thomas’s full-size image here. Location: city of San Bruno, county of San Mateo, California, USA. Date: 27 November, 2017.
Thomas says, “I found this one crawling on our car, a Nissan Leaf. Did it really know it was a Leaf?”
Elm Leaf Beetle (Xanthogaleruca luteola)
Elm leaf beetle, Xanthogaleruca luteola, subfamily Galerucinae, family Chrysomelidae (the leaf beetles),
□ The elm leaf beetle may be greenish in color (as shown here) or yellow. It is a pest species on elm trees — the larvae of this beetle are leaf skeletonizers, which means that they eat the green parts of leaves, so only the veins are left behind. For more information and to see the yellow form of the elm leaf beetle, click here.
Photographed and identified to order by: Robert Moelder. Identified to species by: KnowYourInsects.org. Location: Cashmere, Washington, USA. Date: 11 April, 2019.
Flea Beetles (subfamily Galerucinae)
Flea beetles, subfamily Galerucinae, family Chrysomelidae (the leaf beetles),
Flea beetles get their name from their amazing jumping ability, similar to that of Fleas. Flea Beetles, however, are not related to Fleas. Fleas fall under a completely separate insect order, the Siphonaptera. Read about fleas here.
Photographed and identified by: Abang Albert Fomumbod, who is a Ph.D. student working on resistance of okra (the plant shown here) to aphids. Location: Cameroon (specifically AVRDC/IITA station, Nkolbisson, Yaounde Cameroon). Date: September 2014.
Flea Beetles (subfamily Galerucinae)
Flea beetles, subfamily Galerucinae, family Chrysomelidae.
□ Close-up of the flea beetles. Different species of Flea Beetles often favor specific plants. Those in this photo are dining on okra leaves.
Photographed and identified by: Abang Albert Fomumbod. Location: Cameroon (specifically AVRDC/IITA station, Nkolbisson, Yaounde Cameroon). Date: September 2014.
Red-Headed Flea Beetle (Systena frontalis)
Red-headed flea beetle, Systena frontalis, subfamily Galerucinae, family Chrysomelidae.
□ This red-headed flea beetle gets its name from the dark-red head (the color is just visible in this photo) and its robust, jumping hind legs. The “knees” (the joint between the femur and tibia) are clearly seen on either side of the abdomen. Jumping hind legs are not very common among the beetles, so it is a great find!
Photographed by: Will Plemmons. Identified by: KnowYourInsects.org. Location: Kalamazoo, Michigan, USA. Date: 14 August, 2019.
Add your photo here! Aquatic Leaf Beetle (Donacia spp.)
Aquatic leaf beetle in the genus Donacia, subfamily Donaciinae, family Chrysomelidae.
Aquatic leaf beetles are usually found amid reeds and other emergent aquatic vegetation in ponds, shallow lakes and streams. Most, like this one, are metallic.
Photographed by: Leah McPherson. Identified by: Mark O'Brien. Location: southeastern Michigan, USA. Date: 21 June, 2019.
Scarlet Lily Leaf Beetle (Lilioceris lilii)
Scarlet lily leaf beetle, Lilioceris lilii, subfamily Criocerinae, family Chrysomelidae.
□ According to Bugguide.net, the scarlet lily leaf beetle is a Eurasian species that first came to Montreal, Canada, in the 1940s and has spread into the United States. It is believed that it spread via nursery-bought lilies, but now it has also gotten into wild lilies in the U.S.
Photographed by: Duane Schultz. Identified by: KnowYourInsects.org. Location: Wilson, New York, USA. Date: 14 May, 2017.
Duane says this beetle is eating their lily plants.
Cereal Leaf Beetle (Oulema melanopus or Oulema rufocyanea)
Cereal leaf beetle, either Oulema melanopus or Oulema rufocyanea, subfamily Criocerinae, family Chrysomelidae.
□ The cereal leaf beetle has metallic green elytra (forewings), on an otherwise orange-red body.
□ Note: Without dissecting the beetle, it is nearly impossible to tell whether it is the species Oulema melanopus or Oulema rufocyanea, although the latter is much more rare. Photographed and identified by: Jean-Louis Metzger. Location: Oxford, England, UK. Date: 28 March, 2019.
Cereal Leaf Beetle (Oulema melanopus or Oulema rufocyanea)
Cereal leaf beetle, either Oulema melanopus or Oulema rufocyanea, subfamily Criocerinae, family Chrysomelidae.
□ The cereal leaf beetle is a small beetle — the photographer says this one was just 5 mm (0.2 inches) long, and gets its common name from its preferred diet of oats and cereal grains.
Photographed and identified to order by: Bryan Wenham-Baker. Identified by: KnowYourInsects.org. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 6 April, 2019.
Bryan found this one on the inside of his patio door.
Zygogramma heterothecae
Leaf beetle, Zygogramma heterothecae, subfamily Chrysomelinae, family Chrysomelidae.
□ This leaf beetle, which is associated with camphorweed (Heterotheca subaxillaris), looks very similar to the Calligrapha beetles in the next couple of photos. Both have markings that look like calligraphy. Notice that the head and thorax on this Leaf Beetle have a dark, brick-red color, while those of the Calligrapha look either black or deep green.
Photographed by: Julie Brown. Identified by: KnowYourInsects.org. Location: Haxtun, Colorado, USA. Date: 18 July, 2017.
Elm Calligrapha (Calligrapha scalaris)
Calligrapha beetle in the genus Calligrapha, quite possibly an Elm Calligrapha, Calligrapha scalaris, subfamily Chrysomelinae, family Chrysomelidae.
□ The elm calligrapha has some variety in its markings. Many have the pattern shown here: a long blotch down the middle of the back, a boot-shaped marking at each “shoulder”, as well as a variety of smaller spots.
Photographed and identified to order by: Jacqulyn Stark. Identified to genus and tentative species by: KnowYourInsects.org. Location: Houston, Texas, USA. Date: 25 February, 2019.
Jacqulyn found it on a picnic table in the shade. She says, “I don’t know what it is, but it’s cute. According to a friend, it’s a cow.”
Calligrapha beetle (Calligrapha spp.)
Dogwood calligrapha, also known as a Dogwood Leaf Beetle, Calligrapha philadelphica, subfamily Chrysomelinae, family Chrysomelidae.
Dogwood calligrapha beetles are often found (unsurprisingly) on dogwood plants, but will also visit nearby willow plants. Sometimes, they will share a dogwood plant with another species of calligrapha beetle called the Common Willow Calligrapha (Calligrapha multipunctata).
Photographed and identified to genus by: Emily Day. Identified to species by: Bill Mertz. Thank you, Bill! Location: Pinhoti trail, Alabama, USA. Date: 21 April, 2020.
Emily says, “This beetle attached itself to my niece’s backpack while hiking on the Pinhoti trail in Alabama. We loved its tribal markings and wanted to know if it was a ladybug. I know from your site that it is a calligraphy beetle.” KnowYourInsects.org says, “Glad you found it!”
Calligrapha beetle (Calligrapha philadelphica)
Dogwood calligrapha, also known as a dogwood leaf beetle, Calligrapha philadelphica, subfamily Chrysomelinae, family Chrysomelidae.
□ This photo shows off the gold metallic sheen in this dogwood calligrapha. The head and pronotum (the shield covering the thorax behind the head) looks black, but in certain light, it will appear as a deep metallic green.
Photographed by: Melissa Bishop. Identified by: KnowYourInsects.org. Location: Parma, Michigan, USA. Date: 22 May, 2020.
Add your photo here! Mint Beetle (Chrysolina herbacea)
Mint beetle, possibly Chrysolina herbacea, subfamily Chrysomelinae, family Chrysomelidae.
□ The coloring of this mint beetle, several of which are shown on a mint plant, looks different depending on the light and angle of view. They appear to be Mint Beetles, even though this species is usually found in central Asia and Europe, rather than in India where this photo was taken.
Photographed by: Syed Gazanfar. Identified by: entomologist Fredric Vencl of Stony Brook University and the National Museum of Natural History at the Smithsonian Institution. Thank you, Dr. Vencl! Location: Kashmir, India. Date: 24 April, 2018.
Syed says, “We have abundance of wild mint growing here on the roadsides. I’ve seen this beetle since spring, mating on almost all the plants.”
Bloody-Nosed Beetle (Timarcha tenebricosa)
Bloody-nosed beetle, also known as a blood-spewing beetle, Timarcha tenebricosa, subfamily Chrysomelinae, family Chrysomelidae.
□ Find out how this bloody-nosed beetle got its name by reading the photographer’s comment below. Also, see another view of this beetle in the next photo.
Photographed and identified by: Bryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: June, 2018.
Bryan says, “It’s said that when it’s disturbed, it oozes a red liquid from its front end, but not what I’ve seen so far!” KnowYourInsects.org says, “The liquid is indeed insect blood, which is called hemolymph. The hemolymph is distasteful to predators, so oozing a droplet is a good defensive maneuver.”
Bloody-Nosed Beetle (Timarcha tenebricosa)
Bloody-nosed beetle, also known as a blood-spewing beetle, Timarcha tenebricosa, subfamily Chrysomelinae, family Chrysomelidae.
□ Another nice view of the bloody-nosed beetle, this one a top view.
Photographed and identified by: Bryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 29 April, 2018.
Bryan says “this cute little beetle” was about 10–12mm in length.
Bloody-Nosed Beetle (Timarcha tenebricosa)
Bloody-bosed beetle, also known as a blood-spewing beetle, Timarcha tenebricosa, subfamily Chrysomelinae, family Chrysomelidae.
□ See the photographer’s comments below about the bloody-nosed beetle’s amazing feet with their expanded tarsal pads and the pair of small hooks at the tips.
Photographed and identified by: Bryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 19 August, 2019.
Bryan says “When one considers how slowly this beetle moves, it’s certainly very well equipped with footwear. Apart from the customary pair of hooks, the feet seem extra-large in this photo, three segments, and also the yellow edges of its footpads.... Nevertheless, since it can’t fly, probably gives it more confidence in this big wide world!”
Colorado Potato Beetle (Leptinotarsa decemlineata)
Colorado potato beetle, Leptinotarsa decemlineata, subfamily Chrysomelinae, family Chrysomelidae.
□ The Colorado potato beetle is a major pest of potato plants, and will also attack tomato and pepper plants.
Photographed and identified by: Leslie Mertz. Location: Kalkaska County, Michigan, USA. Date: 28 May, 2012.
Colorado Potato Beetle (Leptinotarsa decemlineata)
Colorado potato beetle, Leptinotarsa decemlineata, subfamily Chrysomelinae, family Chrysomelidae.
□ Compare this Colorado potato beetle to the following photos of the false potato beetle, which is very similar except for the strip of brown running down the center of the False Potato Beetle’s back — at the inner edge of each of the two elytra (the hardened forewings that cover the abdomen). The Colorado Potato Beetle lacks the strip of brown.
Photographed by: Denise Rulason. Identified by: KnowYourInsects.org. Location: Mayville, Michigan, USA. Date: 4 August, 2020.
False Potato Beetle (Leptinotarsa juncta)
False potato beetle, Leptinotarsa juncta, subfamily Chrysomelinae, family Chrysomelidae.
□ The false potato beetle has a brown stripe down the middle of its back and an additional brown stripe between two of the black stripes on each of the two elytra, which is also visible in this photo. These stripes help distinguish it from the similar-looking Colorado Potato Beetle.
Photographed by: Elizabeth Boyle. Identified by: KnowYourInsects.org. Location: West Milford, New Jersey, USA. Date: 11 June, 2017.
False Potato Beetle (Leptinotarsa juncta)
False potato beetle, Leptinotarsa juncta, subfamily Chrysomelinae, family Chrysomelidae.
□ Unlike the Colorado potato beetle, the false potato beetle is not an agricultural pest. Rather, it eats plants usually considered weeds, such as horsenettle and ground cherry.
Photographed and identified to order by: Bill Schwartz. Identified to species by: KnowYourInsects.org. Location: Gettysburg, PA, USA. Date: 20 August, 2014.
Add your photo here! Swamp milkweed leaf beetle (Labidomera clivicollis)
Swamp milkweed leaf beetle, Labidomera clivicollis, subfamily Chrysomelinae, family Chrysomelidae.
□ The color and pattern of the swamp milkweed leaf beetle is highly variable. Some are red, some orange, and some are ivory-colored. Black spotting is always present, but the spots may be much more or less extensive in some individuals.
Photographed by: Bea Cuthbertson. Identified by: Leslie Mertz. Location: on the border between Hillsdale and Lenawee counties, Michigan, USA. Date: 8 September, 2015.
Bea says, “It was roughly 3/8"–1/2" total.”
Clavate Tortoise Beetle (Plagiometriona clavata)
Clavate tortoise beetle, Plagiometriona clavata, subfamily Cassidinae, family Chrysomelidae.
□ Tortoise Beetles, like the clavate tortoise beetle shown here, have a wide turtle-like upper shell, the edges of which are transparent.
Photographed and identified by: Leslie Mertz. Location: Kalkaska County, Michigan, USA. Date: 12 June, 2012.
Clavate Tortoise Beetle (Plagiometriona clavata)
Clavate tortoise beetle, Plagiometriona clavata, subfamily Cassidinae, family Chrysomelidae.
Photographed and identified by: Leslie Mertz. Location: Kalkaska County, Michigan, USA. Date: 12 June, 2012.
Tortoise Beetle (Aspidimorpha spp.)
Tortoise beetle in the genus Aspidimorpha, possibly Aspidimorpha sanctaecrucis, subfamily Cassidinae, family Chrysomelidae.
Photographed by: Spoorthi Sv. Identified by: KnowYourInsects.org. Location: Shivamogga (Shimoga), Karnataka state, southwest India. Date: 7 March, 2018.
Tortoise Beetle (Physonota spp.)
Tortoise Beetle in the genus Physonota, subfamily Cassidinae, family Chrysomelidae.
□ This stunningly beautiful Tortoise Beetle is described wonderfully by the photographer: “They look like magical chocolates wrapped in gold... under a clear fingernail.” This beetle’s underside (at right) has a quite lovely metallic sheen.
Photographed by: Dustin Smith. Identified by: KnowYourInsects.org. Location: Oaxaca, Mexico. Date: 20 August, 2019.
Dustin says, “These little gems join me for breakfast regularly.”
Tortoise Beetle (Cassida circumdata)
Tortoise beetle, Cassida circumdata, subfamily Cassidinae, family Chrysomelidae.
□ This species of tortoise beetle is metallic green and black, but the pattern can vary. One typical pattern is seen here — a black U-shaped band around the back and a broken band down the middle of the middle of the back — is one pattern. Another pattern is green with mottled black all over. In both cases the outside of the back is clear (its legs are visible beneath the clear section).
Photographed by: Bern Jericho. Submitted by: Nickolas C. Identified by: KnowYourInsects.org. Location: Guam. Date: 4 June, 2020.
Tortoise Beetle (Cassidinae)
Tortoise beetles, subfamily Cassidinae, family Chrysomelidae.
□ This pair of photos shows the dorsal and ventral (top and bottom) views of this tortoise beetle. See Dustin’s comment below about the amazing diversity in Mexico.
Photographed and identified by: Dustin Smith. Location: Oaxaca, Mexico. Date: 22 August, 2020.
Dustin says, “I am still surrounded by weird and exotic insects, spiders, crocodiles, and snakes. I have only seen 3 of these guys, but again they caught my attention.”
Tortoise Beetle pupa (subfamily Cassidinae)
Tortoise beetle, pupa, subfamily Cassidinae, family Chrysomelidae.
□ Entomologist Poorani Janakiraman of the National Bureau of Agricultural Insect Resources in Bangalore, India, identified this as a pupa of a tortoise beetle.
□ Many insects have larvae or pupae that have brown and white patterning like this. It is believed that this type of patterning gives them the appearance of bird droppings, which helps to keep potential predators from recognizing them as prey.
Photographed by: Arkopal Gupta. Identified by: Poorani Janakiraman of the Indian Council of Agricultural Research. Thank you, Dr. Janakiraman! Location: West Bengal, India. Date: 25 February, 2018.
Tortoise Beetle (Laccoptera nepalensis)
Tortoise beetle, Laccoptera nepalensis, subfamily Cassidinae, family Chrysomelidae.
□ This tortoise beetle’s reddish back is sculpted with ridges, and punctuated with black spots.
□ As in many other tortoise beetles, the pronotum and elytra are flared out at the edges, somewhat similar to a turtle shell that covers its legs. Not all members of this subfamily (Cassidinae) have this characteristic. An example is the leaf beetle in the genus Callispa, shown elsewhere on this page.
Photographed by: Bhuvan Raj. Identified by: KnowYourInsects.org. Location: Bangalore, Karnataka, India. Date: 25 August, 2019.
Leaf Beetle (Callispa spp.)
Leaf beetle in the genus Callispa, subfamily Cassidinae, family Chrysomelidae.
□ This leaf beetle displays a gradual color change from front to back, and antennae that arise from the head quite close together.
□ Note: This beetle is a member of the tribe Callisipini, which was once classified in the subfamily Hispinae.
Photographed and identified to family by: Eyka Abu Hassan. Identified to genus by: entomologist Michael Geiser from the Natural History Museum in London. Thank you, Dr. Geiser! Location: Malaysia. Date: 11 May, 2020.
Dr. Geiser says, “I am not able to tell which Callispa species it is. There are a few keys, but many of the relevant characters can’t be judged from this photo. Also there might still be some undescribed or unrecorded species in Malaysia, further complicating things.”
Case-Bearing Leaf Beetle (Cryptocephalus leucomelas)
Case-bearing leaf beetle, Cryptocephalus leucomelas, subfamily Cryptocephalinae, family Chrysomelidae.
□ This case-bearing leaf beetle has an interesting pattern of stripes on the pronotum (the shield covering the thorax); and spots and blotches on its elytra (the pair of hard forewings that cover its abdomen). See additional comments from Edward Riley of Texas A&M University, below.
Photographed and identified to order by: Robert Carpenter. Identified to species by: Edward Riley, research assistant with the Texas A&M University Insect Collection. Thank you, Edward! Location: Kerrville, Texas, USA. Date: 14 December, 2016.
Edward says, “The larvae construct and live in cases on the soil surface and feed on fallen leaves. Adults eat foliage of willow and poplar.”
Mimosestes Seed Beetle (Mimosestes amicus)
Mimosestes seed beetle, Mimosestes amicus, subfamily Cryptocephalinae, family Chrysomelidae.
□ A careful look will reveal a rosy hue in about the middle of the gray wings. Female mimosestes seed beetles lay their eggs in plants in the genus Parkinsonia, which includes plants known as Foothills Palo Verde, Blue Palo Verde, and in Velvet Mesquite.
Photographed by: Betty-Lou Archibald. Identified by: KnowYourInsects.org. Location: Apache Junction, Arizona, USA. Date: 7 November, 2017.
Betty-Lou describes this one as being able to hop or jump, and also fly.
Leaf Beetle (Cryptocephalus fulgaratus)
Leaf beetle (no other common name), Cryptocephalus fulgaratus, subfamily Cryptocephalinae, family Chrysomelidae.
□ According to entomologist Robert Barney (who identified this beetle), this leaf beetle is not a common species.
Photographed by: Seif Naqvi. Identified by: Robert J. Barney, Ph.D., professor emeritus at West Virginia State University. Thank you, Dr. Barney! Location: Lexington, Kentucky, USA. Date: 8 September, 2017.
Seif’s mother Kathleen says, “KY. I found this bug in a branch in my peach tree.”
Leaf Beetle (Cryptocephalus irroratus)
Leaf beetle (no other common name), Cryptocephalus irroratus, subfamily Cryptocephalinae, family Chrysomelidae.
□ This leaf beetle (shown in slightly different angles) is about the size of a ladybug. This particular individual has yellowish-colored patterning on a black background, but many members of this species have a reddish background instead. It is an introduced species to Florida, where it was photographed.
Photographed by: Marv Goldberg. Identified by: KnowYourInsects.org. Location: The Villages, Florida, USA. Date: 5 June, 2019.
Marv says, “This guy was so cute!”

Dogbane Beetle (Chrysochus auratus)
Dogbane beetle, Chrysochus auratus, subfamily Eumolpinae, family Chrysomelidae.
□ Look at that color! Not surprisingly, the dogbane beetle eats the plant known as Common Dogbane (Apocynum cannabinum) — the larvae (grubs) munch on the roots, and the adult beetles nibble at the leaves.
Photographed and identified by: Kelly McKinne (@gonzonaturalist). Location: northern Ohio, USA. Date: 6 July, 2016.
Colapsis Beetle (Colapsis spp.)
Colapsis beetle in the genus Colapsis, subfamily Eumolpinae, family Chrysomelidae.
□ Several species in this genus of colapsis beetle look nearly identical. One is known by the scientific name of Colaspis pseudofavosa, which is sometimes called Colaspis floridana as it is found in Florida where this photo was taken. Colaspis pseudofavosa feeds on blueberries and pecans, as well as other things, such as the southern wax myrtle/bayberry tree, according to the University of Florida Institute of Food and Agricultural Sciences.
Photographed by: Marv Goldberg. Identified by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 23 April, 2019.

Lymexylidae, the ship timber beetles

Ship Timber Beetle, family Lymexylidae
Ship timber beetle, family Lymexylidae.
□ Very unusual — and huge — eyes on this ship timber beetle! See the next photo to get an appreciation for how long an abdomen this beetle has.
Photographed by: Jorge “Izzy” Irizarry. Identified by: KnowYourInsects.org. Location: Puerto Rico. Date: 29 September, 2015.
Jorge says it “was very loud when flying. It died, but before it did it laid around 100 eggs.”
Ship Timber Beetle, family Lymexylidae
Ship timber beetle, family Lymexylidae.
□ This photo shows the unique body shape of this ship timber beetle. Photographed by: Jorge “Izzy” Irizarry. Identified by: KnowYourInsects.org. Location: Puerto Rico. Date: 29 September, 2015.
Ship Timber Beetle, family Lymexylidae
Hatching eggs of the ship timber beetle, family Lymexylidae.
□ Although they are called ship timber beetles, these insects will bore into living trees in addition to the wood of ships and other structures.
Photographed by: Jorge “Izzy” Irizarry. Identified by: KnowYourInsects.org. Location: Puerto Rico. Date: 29 September, 2015.

Trogossitidae, the bark-gnawing beetles

Bark-Gnawing Beetle (Temnoscheila chlorodia)
Bark-gnawing beetle, Temnoscheila chlorodia, subfamily Trogossitinae, Trogossitidae.
□ A feature of this species of bark-gnawing beetle is the little crease on its head between the eyes.
Photographed and identified by: Robert E. Carpenter. See Robert’s slow-motion insect videos here. Location: Kerrville, Texas, USA. Date: 15 December, 2016.
Robert says, “Found under bark of dead Box Elder Tree.”
Bark-Gnawing Beetle (Temnoscheila chlorodia)
Bark-gnawing beetle, Temnoscheila chlorodia, subfamily Trogossitinae, Trogossitidae.
□ This bark-gnawing beetle has a metallic appearance, and may be green, purplish-black, or bluish-black. Photographed by: Aven Wright McIntosh. Submitted by: Preston French. Identified by: KnowYourInsects.org. Location: Eugene, Oregon, USA. Date: 25 May, 2020.

Cleridae, the checkered beetles

Red-Legged Ham Beetle, family Lymexylidae
Red-legged ham beetle, Necrobia rufipes, subfamily Korynetinae, family Cleridae.
□ A small insect at just 4.5 mm long (less than 0.2 inches), the red-legged ham beetle has a metallic blue-green back and reddish-brown to orange legs. Its antennae are also reddish-brown to orange with black, clubbed tips. This little beetle eats dried fish, and also feeds on some fly larvae, according to the Food and Agriculture Organization of the United Nations.
Photographed by: Suzanne Cuomo<. Identified by: KnowYourInsects.org. Location: Wyckoff, New Jersey, USA. Date: 22 March, 2019.
Red-Legged Ham Beetle, family Lymexylidae
Red-legged ham beetle, Necrobia rufipes, subfamily Korynetinae, family Cleridae.
□ The photographer reports that she found larvae/grubs of the red-legged ham beetle in a bag of dog food, and the adults nearby. These beetles eat meat products, particularly dried meat, and have been known to get into dog food and also pet stores, and are pests in natural history museums, where they nibble at taxidermy mounts.
Photographed by: Gina Mastrogiovanni. Identified by: KnowYourInsects.org. Location: New Jersey, USA. Date: 16 September, 2019.

Ant Beetle, family Lymexylidae
Ant beetle, also known as a European red-bellied clerid, Thanasimus formicarius, subfamily Clerinae, family Cleridae.
□ The ant beetle has strong jaws perfect for its diet: It crunches through the carapace of adult bark beetles, often first dismembering them so they cannot run away. It will also eat the grubs of bark beetles. As the photographer found (see the comment below), it will also use its jaws in defense. This species, shown here in dorsal and ventral (top and bottom) views, has a distinctive and quite handsome pattern on its elytra (the pair of wings covering its back).
Photographed by: Howard Toon. Identified by: KnowYourInsects.org. Location: Hathern, England, UK. Date: 22 March, 2019.
Howard says, “It is about 10mm long, and I just felt a bite or a sting on my neck and caught this insect.”

Carabidae, the ground beetles

Fiery hunter (Calosoma calidum)
Fiery hunter, Calosoma calidum, subfamily Carabinae, family Carabidae.
□ The fiery hunter is sometimes called a fiery searcher. A large beetle at about 1.5 inches (3.8 cm), this black beetle has rows of red depressions (called fovea) on its back. Its mouthparts, including the finger-like palps, can be seen in the shadow. Note: This species was once listed under the genus Callisthenes.
Photographed and identified by: Leslie Mertz. Location: Kalkaska County, Michigan, USA. Date: 24 May, 2012.
Leslie says, “Look at the texture on its elytra (its back), especially highlighted with those tiny red dots. Gorgeous!”
Caterpillar Hunter (Calosoma spp.)
Caterpillar hunter, larva, in the genus Calosoma, subfamily Carabinae, family Carabidae.
□ This beetle larva looks like it is covered in black armor plates. They are called caterpillar hunters for good reason: Both the larva and the adult do eat caterpillars.
□ It is difficult to distinguish between the larvae of different species in this genus. One possibility is the Black Caterpillar Hunter Calosoma sayi — the adult is a dull black with ridges and tiny red indententations on its elytra (the wings that cover its back). To see the adult Black Caterpillar Hunter, click here.
Photographed by: Douglas Cox. Identified by: KnowYourInsects.org. Location: Canyon Lake, Texas, USA. Date: 28 April, 2020.
Douglas says, “It played dead for about a minute so I could photograph it, then ran off.”
Purple-Rimmed Carabus (Carabus nemoralis)
Purple-rimmed carabus, also known as the European ground beetle, bronze ground beetle or bronze carabid, Carabus nemoralis, subfamily Carabinae, family Carabidae.
□ The purple-rimmed carabus, which is also known as a European Ground Beetle, was introduced to the United States, where this photo was taken, from its native Europe. Note the color variation in the species between this and the next photo.
Photographed and identified to genus by: Ryan King. Identified to species by: KnowYourInsects.org. Location: Fairview, Michigan, USA. Date: 19 April, 2019.
Ryan says, “I happened upon a beetle under a log ... that looked rather interesting.”
Purple-Rimmed Carabus (Carabus nemoralis)
Purple-rimmed carabus, also known as the European ground beetle, bronze ground beetle or bronze carabid, Carabus nemoralis, subfamily Carabinae, family Carabidae.
□ The diet of the purple-rimmed carabus includes slugs, snails, centipedes and millipedes. Gardeners often find it during the day under leaf litter. This flightless, nocturnal beetle has a greenish-bronze coloration with hints of purple or reddish-copper around the edges, and also has tiny, gold-centered depressions (called fovea) on its back.
Photographed and identified to family by: Karen Bradfield. Identified to species by: KnowYourInsects.org. Location: Haute Vienne, France. Date: 30 January, 2020.
Karen says, “A warmish but wet evening, he was climbing the wall near my back door.”

Ground Beetle or Harp Beetle (Bradycellus californicus)
Ground beetle, also known as a harp beetle, Bradycellus californicus, subfamily Harpalinae, family Carabidae.
□ This ground beetle’s body has a finish like a polished, brown, patent-leather shoe. Like many species in this subfamily, the thorax is smooth, while the elytra (wings covering the abdomen) have slight ridges on them. The beetle uses the four finger-like palps on its mouthparts (two labial palps and two maxillary palps) to feel, taste and manipulate food items.
□ The insect leg has two small sections called a coxa and trochanter between the body and the femur (“thigh”), but in some insects, the trochanter is enlarged, as it is in this Ground Beetle. The enlarged trochanter is visible in the hind leg in the center photo, and hangs down alongside the femur up near the body.
Photographed and identified to order by: Thomas Langhans. Identified by: KnowYourInsects.org. See Thomas’s full-size images here, here and here. Location: city of San Bruno, county of San Mateo, California, USA. Date: 12 February, 2020.

Tenebrionidae, the darkling beetles

Darkling Beetle (Eleodes)
Darkling beetle, probably in the genus Eleodes, subfamily Tenebrioninae, family Tenebrionidae.
Darkling beetles are sometimes called clown beetles, because of their habit of running around rather crazily (see the photographer’s comment below) and sometimes doing a headstand when they are threatened. They are also sometimes called stink beetles because one of their defensive mechanisms is to emit a smelly secretion from their rear ends.
Photographed and identified to order by: Thomas Langhans. Identified by: KnowYourInsects.org. See Thomas’s full-size images here and here. Location: city of South San Francisco, county of San Mateo, California, USA. Date: 28 April, 2017.
Thomas says, “This one was in a real hurry to get somewhere. It was large, I can only guess now, perhaps about 4 cm (1.6 inches).”
Darkling Beetle (Ocnodes, Tenebrionidae)
Darkling beetle in the genus Ocnodes, possibly Ocnodes scabricollis, subfamily Pimeliinae, family Tenebrionidae.
□ Like other members of this family, this darkling beetle’s antennae each have 11 segments; each of its big compound eyes are notched by a ridge (visible between the eye and the antenna in this photo); and it has a 5-5-4 arrangement, which means that the front leg tarsus (the last part of the leg before the final claw) has five segments, the middle leg tarsus has five segments, and the hind leg tarsus has four segments.
Photographed and identified to order by: David Meredith. Identified to tribe (Sepidiini) by: KnowYourInsects.org. Identified to genus and tentative species by: Marcin Jan Kamiński, Museum and Institute of Zoology of the Polish Academy of Sciences. Thank you, Dr. Kamiński! Location: Botswana, Africa. Date: November 2019.
Darkling Beetle (Morica planata)
Darkling beetle, Morica planata, subfamily Pimeliinae, family Tenebrionidae.
□ Most beetles raise their hard forewings (called elytra), unfold the pair of membranous flight wings that lie underneath, and fly away. With this species of darkling beetle, however, the elytra are fused, so they cannot fly. Notice this species’ characteristic flattened pronotum behind the head.
Photographed and identified to order by: Sanne Houwing. Identified to species by: KnowYourInsects.org. Location: Tibi, Valencia, Spain. Date: 14 June, 2018.
Sanne says, “We encountered this flatheaded fellow at breakfast in Spain.”
Darkling Beetle (Pimeliinae)
Darkling beetle in the subfamily Pimeliinae, family Tenebrionidae.
□ Although it may look a bit like a squirrel storing nuts in its cheeks, the exaggerated sideward extensions of this darkling beetle’s head are a permanent part of its overall impressive structure.
Photographed by: Quintin Naude. Submitted and identified to suborder by: Dawid Naude (Quintin’s father). Location: Kuzuko Lodge, Eastern Cape, South Africa. Date: 17 February, 2019.
KnowYourInsects.org loves it when families work together! Great job, Quintin and Dawid!
Flour Beetle (Tribolium spp.)

□ There are several species of flour beetle, and the two that are especially common in houses just about everywhere in the world are the red flour beetle (Tribolium castaneum) and the confused flour beetle (Tribolium confusum. These tiny beetles look almost identical, and both feed on flour and other grains people store in the pantry. More information about these beetles is available here.
Photographed by: Fatima Amer. Identified by: KnowYourInsects.org. Location: Dammam, Eastern Province, Saudi Arabia. Date: 18 March, 2019.
Fatima says it is about 4mm (0.15 inches) long. She has discovered a few in her apartment. KnowYourInsects.org says, “They are definitely good and sneaking into homes!”

Anthicidae, the antlike flower beetles

Monoceros Beetle (Notoxus desertus)
Monoceros beetle, Notoxus desertus, subfamily Notoxinae, family Anthicidae.
□ The “horn” projecting forward over the head is a giveaway for the monoceros beetle. This beetle is one of the group often described as ant-like. In fact, the submitter described it as about the size of a pea or “small like an ant.” This beetle has two black spots on its back, plus a V-shaped band. See the description in the comment below.
Photographed by: Autumn Highstreet. Submitted by: J. H. Highstreet. Identified by: KnowYourInsects.org. Location: Michigan, USA. Date: 17 June, 2019.

Spotted pine sawyer, female, Monochamus clamator, subfamily Lamiinae, family Cerambycidae.
□ Among the spotted pine sawyers, males have much longer antennae than females. For more information on this beetle, click here.
Photographed by: Sharon Younie. Identified by: KnowYourInsects.org. Location: Outside Colorado Springs, Colorado, USA. Date: 14 January, 2018.
After learning the identity of this beetle, Sharon says, “It makes sense too, since I live on a lot heavily treed with ponderosa pines. We are located in proximity to burned areas from 2013 Black Forest, Colorado, fires. Although we have few if any dead/dying trees on our property, I realize that I did not notice these bugs before the past few years.”
Long-Horned Beetle (Morimus asper funereus)
Long-horned Beetle, Morimus asper funereus (formerly Morimus funereus), subfamily Lamiinae, family Cerambycidae.
□ This black-spotted, gray long-horned beetle lives in dead or dying wood, especially in old-growth or dense forests. This species is “vulnerable,” which means its numbers are decreasing, in this case because of woodland practices that remove branches and other dead wood from forests.
Photographed by: Stevica Vojnovic. Identified by: KnowYourInsects.org. Location: Subotica, Serbia. Date: 29 July, 2018.
Mango Stem-Borer (Batocera rufomaculata)
Mango stem-borer, also sometimes called a mango tree borer or tropical fig borer, Batocera rufomaculata, subfamily Lamiinae, family Cerambycidae.
□ The red, angled markings on this adult mango stem-borer’s thorax are characteristic, as is the light-colored heart-shape just behind the thorax, the black raised spots and the few red spots on the elytra (the hardened wings covering its abdomen). And it is large: see the photographer’s comment below.
□ The larvae (grubs) of the mango stem-borer eat the stems and roots of mangos and figs, usually stressed trees, but sometimes healthy ones, and are considered major pests in mango-growing regions. They will, however, also attack other trees, including ficus, avocado, cashew, rubber trees, and many more.
Photographed by: Meem Sarkar. Identified by: KnowYourInsects.org. Location: Bengaluru, Karnataka, India. Date: 13 June, 2020.
Meem says, “In the very early morning, while I was going to brush my teeth, I found this giant insect sitting at one of the sides of a table.” KnowYourInsects.org says, “It is a big beetle: It can grow to 5cm (2 inches) long, and that is not counting the antennae!
Mango Stem-Borer (Batocera rufomaculata)
Mango stem-borer, also sometimes called a mango tree borer or tropical fig borer, Batocera rufomaculata, subfamily Lamiinae, family Cerambycidae.
□ This mango stem borer has a dark background coloration, which makes the red spots rather difficult to see.
Photographed and identified by: Binu Correya. Location: Kerala, India. Date: 25 May, 2020.
Three-Lined Fig-Tree Borer (Neoptychodes trilineatus)
Three-lined fig-tree borer, Neoptychodes trilineatus, subfamily Lamiinae, family Cerambycidae.
□ The three-lined fig-tree borer has amazingly long antennae. The “three-lined”s part of the name refers to the large stripe running down the center of its back and an additional stripe on each side of the body (just barely visible in this photo). In some individuals within this species, the central stripe is reduced to just a little white streak.
□ Its larvae bore into fig trees, as its name implies, but will also bore into other trees, such as mulberry, birch and willow.
Photographed by: Nicole Kinchen. Identified by: KnowYourInsects.org. Location: Louisiana, USA. Date: 12 April, 2020.

Milkweed Longhorn Beetles (Tetraopes annulatus)
Milkweed long-horned beetles, Tetraopes annulatus, subfamily Lamiinae, family Cerambycidae.
□ The milkweed long-horned beetle has four black spots on its pronotum (the shield covering its thorax), in addition to two black spots on each of its forewings (the elytra). It looks almost identical to another beetle in the same genus, Tetraopes pilosus, but the body of Tetraopes pilosus is covered with white or yellowish hairs, which gives it a more faded appearance.
Photographed by: Kim Thiel. Identified by: KnowYourInsects.org. Location: Dickinson, North Dakota, USA. Date: 19 August, 2019.
Kim says, “Just haven’t seen those around much and was curious, as it was in my garden.“

Cottonwood Borer (Plectrodera scalator)
Cottonwood borer, Plectrodera scalator, subfamily Lamiinae, family Cerambycidae.
□ The cottonwood borer grows to 1.25 inches (more than 3 cm) long, not counting the elongate antennae, which can be longer than the body. Its pattern of squarish black marks on a creamy-yellow background set it apart from other beetles. There’s a little bit of pattern variation between individuals (as seen in the next photos).
Photographed and identified by: Mike Toombs. Location: Colorado City, Texas, USA. Date: 18 June, 2018.
Mike took this photo in a backyard with “many older cottonwood trees” there and throughout the city.
Cottonwood Borer (Plectrodera scalator)
Cottonwood borer, Plectrodera scalator, subfamily Lamiinae, family Cerambycidae.
□ Female cottonwood borers dig into the ground and lay their eggs next to cottonwood tree roots. As the larvae (grubs) hatch, they begin eating the roots, and continue to do so for the next one to two years, until they pupate before becoming an adult.
Photographed by: Theresa Smith. Submitted by: Lisa Hetchler. Identified by: KnowYourInsects.org. Location: New Era, Michigan, USA. Date: 5 September, 2019.
Cottonwood Borer (Plectrodera scalator)
Cottonwood borer, Plectrodera scalator, subfamily Lamiinae, family Cerambycidae.
Cottonwood borers not only are pests of cottonwood trees, but also of poplar and willow trees. Larvae live under the bark for a year or two, and adults typically begin emerging in mid-May in Texas, so this one appeared a bit on the early side.

□ Despite the rather large and strong jaws on this brown prionid, the adults are believed to eat very little, if at all. In their short adult lives, the main task is to mate.
Photographed by: Molly Bengelink. Identified by: KnowYourInsects.org. Location: Holland, Michigan, USA. Date: 18 July, 2016.
Molly says, “I have never seen anything like that around our house before and it had us all a little curious (and somewhat uneasy initially).”
Brown prionid (Orthosoma brunneum)
Brown Prionid, Orthosoma brunneum, subfamily Prioninae, family Cerambycidae.
□ The photo at right shows a close-up of the brown prionid, and makes evident the small spines extending from the thorax. Also note the large jaws on this big beetle. The beetle is not aggressive, but if it is provoked (especially if it is cornered and can’t get away), it will defend itself as best it can and might even bite.
Photographed by: Dave Delman. Identified by: KnowYourInsects.org. Location: Tucson, Arizona, U.S. Date: 5 January, 2018.
Dave says, “It was really big!” KnowYourInsects.org says, “Yes, they can reach almost 2 inches long (nearly 5 cm)!”
Brown prionid (Orthosoma brunneum)
Brown Prionid, Orthosoma brunneum, subfamily Prioninae, family Cerambycidae.
□ The brown prionid can grow to between 1–1.9 inches long (2.5–4.8 cm), so it’s a good-sized beetle!
Photographed by: Rob Fox. Identified by: KnowYourInsects.org. Location: Ross (near Pittsburgh), Pennsylvania, USA. Date: 4 August, 2017.
Rob says, “It was approx. 1.5" in length.”
Prionid Beetle (Stenodontes spp.)
Stenodontes Beetle, male, in the genus Stenodontes, subfamily Prioninae, family Cerambycidae.
□ Note the long, narrow jaws on this male stenodontes beetle! The Stenodontes genus has three species: Stenodontes chevrolati, Stenodontes damicornis and Stenodontes exsertus, the latter two of which are found in Puerto Rico, where this photo was taken. Insect expert Antonio Santos-Silva noted that Stenodontes chevrolati is not formally recorded in Puerto Rico, but it may well also occur in that country. From this photo alone, he was unable to determine exactly which species it is.
Photographed by: Juraj Bajgar. Submitted and identified to order by: Clara Bajgar. Identified to family by: KnowYourInsects.org. Identified to genus by: entomologist Antonio Santos-Silva at the University of São Paulo. Thank you Dr. Santos-Silva! Location: Represa Lago Guajataca (about two hours from San Juan), Puerto Rico.

Broad-Necked Root Borer (Prionus laticollis)
Broad-necked root borer, Prionus laticollis, subfamily Prioninae, family Cerambycidae.
□ As their name implies, the brown-necked root borer tunnels into and eats roots of trees and shrubs — usually going after trees and shrubs that are unhealthy. See the female in the next photo.
Photographed and identified to order by: Louise Sandler. Identified to species by: KnowYourInsects.org. Location: Chester County, Pennsylvania, USA. Date: 7 August, 2017.
Louise says, “The head and body were about 2 inches long!”
Broad-Necked Root Borer (Prionus laticollis)
Broad-necked root borer, female, Prionus laticollis, subfamily Prioninae, family Cerambycidae.
□ The broad-necked root borer uses her ovipositor (shown here) as a hypodermic needle to stab into the ground (or in piles of leaves) and lay her eggs there. Once they hatch into larvae (grubs), the larvae eat tree and bush roots. See the male in the previous photo.
Photographed by: Jo-Anne O. Identified by: KnowYourInsects.org. Location: Highlands, New Jersey, USA. Date: 11 July, 2019.
Jo-Anne found this 2-inch (5 cm) beetle in her garden on a July evening.

□ This is an adult female long-horned beetle, and the female of this particular species can reach 3 inches (7.5 cm) in body length. The male is smaller. See the comment below for a fun description of this large beetle.
Photographed by: Juraj Bajgar. Submitted by: Clara Bajgar. Identified by: KnowYourInsects.org. Location: in the mountains about two hours outside San Juan, Puerto Rico. Date: 13 May, 2019.
Clara says, “The bug is moving, thus not in focus. The wings are nicely patterned and it has a few symetrical white dots on the ‘torso.’ ... After making (the photo) lighter and sharper, it looks like a roach dressed up for a wedding.”
Root Borer (Prioninae)
Root borer, subfamily Prioninae, family Cerambycidae.
□ Without a bit more detail in the photo, it is difficult to identify the species. A possibility is the live-oak root borer (Archodontes melanopus).
Photographed and identified to subfamily by: Kirsten Kischuk. Location: Orlando, Florida. Date: 29 October, 2019.
Kirsten says it was about as long as her thumbnail.
Hardwood Stumpborer (Mallodon dasystomus)
Hardwood stumpborer, Mallodon dasystomus, subfamily Prioninae, family Cerambycidae.
□ The hardwood stumpborer may be either black or dark reddish brown, and has two large shiny patches on the thorax, which is otherwise rather dull-looking.
Photographed by: Judie Kahn. Identified by: KnowYourInsects.org. Date: 1 June, 2020. Location: Houston, Texas, USA.
Judie says, “Only saw one. It was in a tub of water. Thought it was dead and took it out. About 10 minutes later it started to move around. I hate to kill anything so I put it in an empty lot with trees. Later it was gone.”
Hardwood Stumpborer (Mallodon dasystomus)
Hardwood stumpborer, Mallodon dasystomus, subfamily Prioninae, family Cerambycidae.
□ The name hardwood stumpborer comes from its larvae, which tunnel into the trunks (or stumps) of a wide variety of hardwood trees, including oak, hickory and maple. The photographer estimated is at about 1.5 inches (3.8 cm) long.
Photographed by: Ronald J. Wisby. Identified by: KnowYourInsects.org. Date: 2 June, 2020. Location: Southwest Louisiana, USA.
Ronald says this beetle gave someone quite a good bite.
Rustic borer (Xylotrechus colonus)
Rustic borer, Xylotrechus colonus, subfamily Cerambycinae, family Cerambycidae.
□ This rustic borer has some gorgeous patterning on its back (the patterning is actually on its hardened forewings, which are called elytra). It is called a borer, because its grubs bore into hardwood trees, such as hickory. This beetle was once in a different genus and had the scientific name of Clytus colonus.
Photographed by: Amy Jones. Identified by: KnowYourInsects.org. Location: Milford, Sussex County, Delaware, USA. Date: 6 May, 2017.
Amy says, “I’ve never seen anything like this before. It showed up in our house yesterday.”
Rustic borer (Xylotrechus colonus)
Rustic borer, Xylotrechus colonus, subfamily Cerambycinae, family Cerambycidae.
□ A characteristic of the rustic borer is the thin, white or cream-colored, undulating line at the base of the elytra (behind its thorax), along with the two broader black bands at the center and toward the tip of the elytra. See the photographer’s comment below to see how she became acquainted with these beetles (hint: she found one in her hair)!
Photographed by: Christina Sun. Identified by: KnowYourInsects.org. Location: East Marion, Long Island, New York, USA. Date: 13 April, 2020.
Christina says, “Here’s another of those dropping bores. This is the sixth one that just falls on my head while sitting the table for a meal. It looks like a Peking opera mask!”
Locust borer (Megacyllene robiniae)
Locust borer, Megacyllene robiniae, subfamily Cerambycinae, family Cerambycidae.
□ This species is called a locust borer because it most notably does damage to black locust trees. Adults are about 3/4 inch long (1.9 cm).
Photographed by: Gordon Goos. Identified by: KnowYourInsects.org. Location: Benton County, Washington, USA. Date: 1 September, 2017.

Mimusop stem borer, Pachyteria dimidiata, subfamily Cerambycinae, family Cerambycidae.
□ The black, sometimes blue-black, of the mimusop stem borer’s body is splashed with a bold yellow band across its back and half-yellow antennae. A wood-boring species, this beetle is considered a pest on trees in the genus Mimusops, which includes the Spanish cherry, also known as an iron wood tree (Mimusops elengi).
Photographed by: Elaine Low. Identified by: KnowYourInsects.org. Date: 2 May, 2020. Location: Malaysia.
Eucalyptus Borer (Phoracantha recurva)
Eucalyptus borer, also known as a eucalyptus long-horned borer, Phoracantha recurva, subfamily Cerambycinae, family Cerambycidae.
□ This eucalyptus borer looks very similar to the closely related species Phoracantha semipunctata, but the latter has more black on its back. Both attack eucalyptus trees, and particularly those trees that are stressed. (See the photographer’s comment below.)
□ The Eucalyptus Borer is native to Australia and Papua New Guinea, but is now found in warmer climates in Europe, including Italy, where it was found in 2006 (and where this photo was taken), South America, North America, and Africa.
Photographed by: Mari C. Identified by: KnowYourInsects.org. Location: Sardinia, Italy. Date: 1 December, 2019.
Upon learning what it was, Mari says, “Then it comes from the Eucalyptus wood that I have at home for the stove!”
Eucalyptus Borer (Phoracantha recurva)
Eucalyptus borer, also known as a eucalyptus long-horned borer, male, Phoracantha recurva, subfamily Cerambycinae, family Cerambycidae.
□ The eucalyptus borer made its way from Australia to southern California in 1995 — this one was found in southern California — and is now found throughout the state. The male, seen here, has little spine-like hairs on the antennae.

Monkey Pod Round-Headed Borer (Xystrocera globosa)
Monkeypod round-headed borer, Xystrocera globosa, subfamily Cerambycinae, family Cerambycidae.
□ A close look at this beetle reveals the two dark stripes running down its back: one on each of its wings. It is known as a monkeypod round-headed borer because it bores into monkeypod trees, which were introduced to and now grow in many parts of Hawaii.
Photographed by: Rikita Turner. Identified by: KnowYourInsects.org. Location: Oahu, Hawaii, USA. Date: 20 September, 2017.
Rikita says, “This was in my ceiling.”
Monkey Pod Round-Headed Borer (Xystrocera globosa)
Monkeypod round-headed borer, Xystrocera globosa, subfamily Cerambycinae, family Cerambycidae.
□ The monkeypod round-headed borer can easily grow to 3.2 cm (1.3 inches) long, and that is just the body. With the antennae, it can be twice that length. This species has spread to warm climates around the world.
Photographed by: Juraj Bajgar. Submitted by: Clara Bajgar. Identified by: KnowYourInsects.org. Location: San Juan, Puerto Rico. Date: 6 September, 2018.
Clara notes the “black ‘eye brows.’
Wasp borer (Neoclytus conjunctus)
Wasp borer, also known as a Western Ash Borer, Neoclytus conjunctus, subfamily Cerambycinae, family Cerambycidae.
□ The wasp borer is a species of high elevations in the western U.S. and up into Canada.
Photographed by: Todd Phelps. Identified by: KnowYourInsects.org. Location: Humboldt County, California, USA. Date: 17 June, 2012.
Todd found this beetle at 2,400 feet elevation near the coast.
Wasp borer (Neoclytus conjunctus)
Wasp borer, also known as a western ash borer, Neoclytus conjunctus, subfamily Cerambycinae, family Cerambycidae.
□ The wasp borer gets its name because its yellow patterning (shown in previous photo) gives the impression of a wasp, and because it makes boreholes, like those shown here in this piece of wood.
Photographed by: Todd Phelps. Identified by: KnowYourInsects.org. Location: Humboldt County, California, USA. Date: 17 June, 2012.
Wasp borer (Neoclytus conjunctus)
Wasp borer, also known as a western ash borer, Neoclytus conjunctus, subfamily Cerambycinae, family Cerambycidae.
□ The pattern on the thorax of this wasp borer is evident in this photo. The wasp borer is also known as a western ash borer because the larvae bore into the wood of dead and dying ash trees. The larvae will also get into other wood, including that of oak and arbutus.
Photographed by: Arnold Lundwall. Identified by: KnowYourInsects.org. Location: Montana, USA. Date: 20 February, 2019.
Gray-Winged Neoclyt-Borer (Neoclytus scutellaris)
Gray-winged neoclyt-borer, Neoclytus scutellaris, subfamily Cerambycinae, family Cerambycidae.
□ The gray-winged neoclyt-borer is distinguished from similar-looking species by the yellow band across the upper back (technically the pronotum). The young (the grubs) bore into in oak and hickory trees.
Photographed by: Christin McMahon. Identified by: KnowYourInsects.org. Location: McKinney, Texas, USA. Date: 2 July, 2018.
Christin found this on her couch, and says, “At first I thought it was some sort of bee, then butterfly — it is rather weak, only somewhat moving its front legs.”
Banded Ash Borer (Neoclytus caprea)
Banded ash borer, Neoclytus caprea, subfamily Cerambycinae, family Cerambycidae.
□ The banded ash borer feeds on sapwood of ash, sometimes hickory and oak, in diseased/stressed, dying, dead (or cut) trees. Females lay their eggs on the bark of these trees, the larvae eventually bore into the tree, and they survive the winter as pupae, transforming into adults and emerging in the early spring. Pupa will transform earlier — in winter months — in firewood that is kept indoors. Most people see Banded Ash Borers in their homes in the winter for this reason.
Photographed by: Arthur Dabrowski. Identified by: KnowYourInsects.org. Location: Greenwood Lake, New Jersey, USA. Date: 27 January, 2019.
Red-Headed Ash Borer (Neoclytus acuminatus)
Red-headed ash borer, Neoclytus acuminatus, subfamily Cerambycinae, family Cerambycidae.
□ The larvae (grubs) of the red-headed ash borer bore into mainly dead or dying hardwood trees, including ash, especially trees that have already fallen.
□ A few features of this beetle include the reddish coloration on the front half of the body, the pattern of yellow stripes on its back (actually the forewings, known as the elytra), and the thickened tips on its antennae.
Photographed by: Emily Pierce. Identified by: KnowYourInsects.org. Location: Manassas, Virginia, USA. Date: 23 July, 2019.
Ivory-marked long-horned beetle (Eburia haldemani)
Ivory-marked long-horned beetle, Eburia haldemani, subfamily Cerambycinae, family Cerambycidae.
□ The doubled light-colored markings are especially noticeable — and elongated — in this beautiful specimen of ivory-marked long-horned beetle.
Photographed by: Windy Bond. Identified by: KnowYourInsects.org. Location: Chattanooga, Tennessee, USA. Date: 19 June, 2018.
Ivory-marked long-horned beetle (Eburia spp)
Ivory-marked long-horned beetle, Eburia spp, subfamily Cerambycinae, family Cerambycidae.
Ivory-marked long-horned beetles sometimes lack the ivory markings, but they retain other features, such as the heavily notched eyes that look almost like the letter “C”, and the two small black bumps on the thorax.
Photographed and identified to family by: Manzeal Khanal. Identified to species by: KnowYourInsects.org. Location: Uvalde, Texas, USA. Date: 9 August, 2019.
Banded Alder Borer (Rosalia funebris)
Banded alder borer, Rosalia funebris, subfamily Cerambycinae, family Cerambycidae.
□ The banded alder borer is black and white or (blue-tinged white) with bands on its antennae and on its back (actually its forewings or elytra), and a large black spot in the center of a white thorax. According to Washington University entomologist Arthur Antonelli, this beetle is sometimes attracted to wet paint. Some believe the paint smell may be similar to beetle’s own pheromones.
Photographed by: Michael Toombs. Identified by: KnowYourInsects.org. Location: Wenatchee, Washington, USA. Date: 22 July, 2018.
Peggy says, “ I’ve never seen one before.”
Rosalia Longicorn (Rosalia alpina)
Rosalia longicorn, also known as the alpine longhorn beetle, female, Rosalia alpina, subfamily Cerambycinae, family Cerambycidae.
□Seen in person, the rosalia longicorn has a bluish tint. According to Beetle Fauna of Germany, this attractive beetle is becoming increasingly rare due to beech deforestation and the removal of dead wood from forests. The female (shown here) has tufts of hair at the black segments of most of her antennae. The male has thinner antennae without the tufts.
Photographed by: Ian Ryding. Identified by: KnowYourInsects.org. Location: central-western France. Date: 21 July, 2019.

Long-Horned Beetle (Anelaphus moestus)
Long-horned beetle, Anelaphus moestus, subfamily Cerambycinae, family Cerambycidae.
□ Many species have no particular common name and simply go by the group common name. This is the case with this long-horned beetle. Members of this species are often much darker brown than the individual in this photo. Note: At one time, the species name was different: Anoplium pinorum.
Photographed by: Phillippe Saieed. Identified by: KnowYourInsects.org. Location: North Carolina, USA. Date: 25 June, 2019.
Flower Longhorn (Bellamira scalaris)
Flower longhorn, Bellamira scalaris, subfamily Cerambycinae, family Cerambycidae.
□ The flower longhorn has an hourglass-like shape to its elytra (the wings covering its back) and an extended abdomen that peeks out beyond the wings. This species had quite a bit of variation in the amount of dark blotching on its elytra from one individual to the next.
Photographed by: Anonymous. Identified by: KnowYourInsects.org. Location: northeastern USA. Date: 31 July, 2019.
Cabbage Palm Longhorn Beetle (Osmopleura chamaeropis)
Cabbage palm longhorn beetle, Osmopleura chamaeropis, subfamily Cerambycinae, family Cerambycidae.
□ Rather distinctive with the black and white striped thorax, the cabbage palm longhorn beetle feeds on cabbage palms (also known as sabal palmetto). Although it is not especially widespread, it can become quite numerous in small areas.
Photographed by: Brooke Almiron. Identified by: KnowYourInsects.org. Location: Oviedo, Florida, USA. Date: 25 April, 2020. Brooke found this beetle on her porch. She says, “Thanks so much for identifying it for me. I was going crazy trying to find it and google had nothing for me.” KnowYourInsects.org says, “Glad we could help!”
Flower Longhorn Beetle (Trigonarthris proxima)
Flower long-horned beetle, Trigonarthris proximas, subfamily Lepturinae, family Cerambycidae.

Red-shouldered Pine Borer (Stictoleptura canadensis)
Red-shouldered pine borer, also known as a red-shouldered beetle Stictoleptura canadensis, subfamily Lepturinae, family Cerambycidae.
□ This red-shouldered pine borer is holding its stiff elytra (stiff forewings) away from its body, allowing the membranous flight wings beneath to be seen.
Photographed by: Alexander Tonkinson. Identified by: KnowYourInsects.org. Location: Wiltshire, UK. Date: 11 August, 2017.
Jessamie Tonkinson, who sent in her husband’s photo, says she saw this one buzzing around the back wall of her house in the garden. She notes that it had most of its wings exposed, and was roughly 12mm (about 0.5 inches) in length.
Black-Spotted Long-Horned Beetle (Rhagium mordax)
Black-spotted long-horned beetle, also known as black-spotted long-horned beetle, Rhagium mordax, subfamily Lepturinae, family Cerambycidae.
□ This black-spotted long-horned beetle has shorter antennae than most of the beetles in this family. The pattern on its elytra (hardened forewings that cover the abdomen) is reminescent of a marled wool sweater.
Photographed by: Daryl Fleming. Submitted by: Helen Williams. Identified by: KnowYourInsects.org. Location: Woodleigh, Devon, UK. Date: 7 May, 2018.
Helen says, “Found this chap in a garden.” She adds, “It’s a lovely looking one.” KnowYourInsects.org agrees!

Cantharidae, the soldier beetles

Goldenrod Soldier Beetles mating (Chauliognathus pensylvanicus)
Goldenrod soldier beetles, Chauliognathus pensylvanicus, subfamily Chauliognathinae, family Cantharidae.
□ Look closely to see the female underneath the male — in this pair of mating goldenrod soldier beetles. As with many insect species, the female is often larger than the male. Instead of sitting on goldenrod, this pair is on milkweed. Compare the Goldenrod Soldier Beetle to the Margined Leatherwing (Chauliognathus marginatus) elsewhere on this page, and note the different orientation of the black bar on the pronotum (thorax) — this helps to distinguish the two.
Photographed by: Diana Koss. Identified by: KnowYourInsects.org. Location: L’Anse, Michigan, USA. Date: 9 August, 2016.
Margined Leatherwing (Chauliognathus marginatus)
Margined leatherwing, Chauliognathus marginatus, subfamily Chauliognathinae, family Cantharidae.

Michael says, “My Dad was involved in horticulture and loved his insects. He would laugh that I took a photo of a soldier beetle and had it posted when I was more interested in a different Beatle growing up...”
Brown leatherwing (Pacificanthia consors)
Brown leatherwing, Pacificanthia consors, subfamily Cantharinae, family Cantharidae.
□ This brown leatherwing has a diet that includes many garden pests, including aphids, citrus mealybugs (known as greenhouse mealybugs in Europe), various caterpillars, and mites, so it is a good one to find it in the yard.
Photographed by: Matt McDowell. Identified by: KnowYourInsects.org. Location: Newark, California, USA. Date: 4 July, 2018.
Soldier beetle (Pacificanthia rotundicollis)
Soldier beetle, Pacificanthia rotundicollis, subfamily Cantharinae, family Cantharidae.
□ “You lookin’ at me?” This soldier beetle seems to be as curious about the photographer as the photographer is about the beetle in this nice shot! This soldier beetle is very similar in appearance to the brown leatherwing seen elsewhere on this page. In fact, both are in the same genus. One difference is that the legs are all orange in this soldier beetle, while they are orange and black in the brown leatherwing.
Photographed and identified by: Iggy Tavares. Location: Big Sky Resort, Montana, USA. Date: June, 2015.
Soldier Beetle (Pacificanthia rotundicollis)
Soldier beetle, Pacificanthia rotundicollis, subfamily Cantharinae, family Cantharidae.
□ This nice view from the top shows the rounded pronotum (the shield covering the thorax) in this soldier beetle. Its species name of rotundicollis refers to the rounded pronotum.
Photographed by: Judi Ragsdale. Identified by: KnowYourInsects.org. Location: Lafayette, (northern) California, USA. Date: 6 June, 2018.
Judi says, “I am a member of a Facebook group of photographers from Flowers From All Over the World and when someone asked me what the insect was I was stumped. Now, I have a name! Thank you for identifying it.” KnowYourInsects.org says, “Glad to help!”

Silphidae, the carrion beetles

Burying Beetle (Nicrophorus sayi)
Burying beetle, also known as a carrion beetle, Nicrophorus sayi, subfamily Nicrophorinae, family Silphidae.
Burying beetles will dig under a dead animal, such as a mouse, and once the mouse has fallen far enough into their hole, the beetles will bury it. The beetles then lay their eggs in the dead animal, the eggs eventually hatch, and the larvae have a ready meal waiting for them.
Photographed by: Mike Bloodsworth. Identified by: KnowYourInsects.org. Location: Eastern Texas, USA. Date: 11 April, 2017.
Mike says, “You know, I have seen them bury dead things over a few hours before but never seen one this colorful.”
Burying Beetle (Nicrophorus sayi)
Burying beetle, also known as a carrion beetle, Nicrophorus sayi, subfamily Nicrophorinae, family Silphidae.
□ Look for the tiny red mites on this burying beetles. The mites look like red spots on the thorax.) The mites will ride on the beetle to a dead animal, then hop off when the beetle arrives at a dead animal. What’s in it for the mites? Tasty maggots on the dead animal!
Photographed by: Mike Bloodsworth. Identified by: KnowYourInsects.org. Location: Eastern Texas, USA. Date: 11 April, 2017.
Mike says, “Upon enlarging the photograph I saw that there were eight mites on the insect and it seemed to be agitated by the mites. I took several shots of it at the time, and then another one about 30 minutes later and all of the mites were gone.”
Sexton Burying Beetle (Nicrophorus investigator)
Red- and black-banded sexton burying beetle, also known simply as a sexton beetle, Nicrophorus investigator, subfamily Nicrophorinae, family Silphidae.
Red- and black-banded sexton burying beetles are good fliers, and may travel a mile to track down the scent of a dead animal. Like other burying beetles, they literally bury dead animals, then lay eggs alongside. The eggs hatch and the larva feed on the dead animal.
Photographed and identified by: Lindsey Christie. Location: Scotland. Date: 24 June, 2017.
Burying Beetle (Nicrophorus defodiens)
Sexton burying beetle, Nicrophorus defodiens, subfamily Nicrophorinae, family Silphidae.
□ This sexton burying beetle is almost a perfect match for the Red and Black Banded Sexton Burying Beetle (pictured elsewhere on this page). This one, however, has this combination of characteristic features: 1) all-black antennae (no dark-red tips); and 2) the rear red patch on each wing is completely surrounded by black.
Photographed and identified to order by: Dave Delman. Identified by: KnowYourInsects.org. Location: Yellowstone National Park, U.S. Date: 4 July, 2017.
Carrion Beetle (Nicrophorus argutor)
Carrion beetle, also known as a burying beetle, Nicrophorus argutor, subfamily Nicrophorinae, family Silphidae.
□ This carrion beetle has maroon or dark-brown markings on a black background, and a black thorax that has a flattened outline. Note: The beige circle at the upper-right behind the thorax is an insect pin and not part of the insect itself.
Photographed and identified to order by: Ulzii Bayar. Identified to species by: KnowYourInsects.org. Location: Mongolia. Date: 7 October, 2019.
Pustulated carrion beetle (Nicrophorus pustulatus)
Pustulated carrion beetle, also known as sexton or carrion beetle, Nicrophorus pustulatus, subfamily Nicrophorinae, family Silphidae.
□ The pustulated carrion beetle has an unusual relationship with snakes. Researchers who were studying rat snakes (the nonvenomous snakes Pantherophis alleghaniensis), found that the snakes’ eggs are often full of the larvae of these beetles, and in some nests, the larvae are destroying every single egg. They hypothesized in an article describing their finding that other egg-laying snakes might also be at risk.
□ Characteristic features of this beetle include: has short elytra (the hardened forewings) with orange/red spots as seen here, and antennae with orange/red tips.
Photographed by: F.M. “Mike” Kraemer III. Identified by: KnowYourInsects.org. Location: Ste. Genevieve County, Missouri, USA. Date: 6 June, 2020.
Mike says he found this beetle caught in carpenter bee trap.
American carrion beetle (Necrophila americana)
American carrion beetle, Necrophila americana, subfamily Silphinae, family Silphidae.
□ This American carrion beetle has a distinctive pale yellow pronotum (the shield covering the thorax) with a black splotch in the center. The adult females lay their eggs on dead animals. When the eggs hatch, the larvae feast on the rotting flesh. Sometimes, the females lay their eggs on — and the larvae consume — fungi instead. Note: This beetle was once listed as being in the Silpha genus.
Photographed by: Janie Smyser. Submitted by: Janie’s husband Chuck. Identified by: KnowYourInsects.org. Location: York County, Pennsylvania, U.S. Date: 14 July, 2019.

Ptinidae, the death-watch and spider beetles (includes Anobiinae)

Smooth spider beetle (Gibbium aequinoctiale)
Spider beetle, probably a smooth spider beetle, Gibbium aequinoctiale, subfamily Ptininae, family Ptinidae.
□ The smooth spider beetle looks rather similar to a red mite. Both are tiny with bead-like, red bodies. The spider beetle has only six legs, while the mite has eight ... but the long antennae on a spider beetle can almost look like an extra pair of legs, which adds to the confusion. For a close-up view of a smooth spider beetle, click here (bugguide.net).
Photographed by: Janet Madison. Identified by: KnowYourInsects.org. Location: Chicago, Illinois, USA. Date: 4 March, 2020.
Janet says, “Found it on a towel as I was loading laundry in the washer.”
Drug store beetle (Stegobium paniceum)
Drug store beetle, also known as a biscuit beetle in the United Kingdom, Stegobium paniceum, subfamily Anobiinae, family Ptinidae.
□ The drug store beetle is a tiny brown beetle with a large pronotum (the shield covering its thorax). This species is common in homes, where it gets into grains and just about anything else, including prescription drugs (which is where the “drug store” part of its name derives). The larvae (grubs) are white. It is a pest almost everywhere in the world. For more information about these beetles, click here (University of Florida).
□ Note: The subfamily Anobiinae was once classified as a family (Anobiidae), and is sometimes still listed as such.
Photographed by: Steve Owczarek. Identified by: KnowYourInsects.org. Location: Shelby Township, Michigan, USA. Date: 9 February, 2020.

Callirhipidae, the Callirhipid Cedar Beetles

Callirhipid Beetle (Callirhipis spp.)
Callirhipid beetle in the genus Callirhipis, subfamily Callirhipinae, family Callirhipidae.
□ The fanned (pectinate) antennae on this callirhipid beetle are nothing short of spectacular. In fact, they are sometimes called feather-horned beetles. Select species in few other families of insects also have amazing antennae, such as the cicada parasite beetles (family Rhipiceridae), the glow worm beetles (family Phengodidae), and even some dcarab beetles (Scarabaeidae), such as the 10-Lined June beetle (Polyphylla decemlineata).
Photographed and identified by: Mettle Brahma, a student of zoology. Great job with the identification! Location: Kokrajhar, Assam, India. Date: 30 April, 2020.

Dermestidae, the dermestid or skin beetles

Larder beetle (Dermestes lardarius)
Larder beetle, Dermestes lardarius, subfamily Dermestinae, family Dermestidae.
Larder beetles (and their larvae) are very common in houses. They are called larder beetles, because they are often found in the larder, which is an old-fashioned term for a pantry room or food-storage cabinet.
Photographed by: Erin Mackay. Identified by: KnowYourInsects.org. Location: Ohio, USA. Date: 3 April, 2017.
Larder beetle (Dermestes lardarius)
Larder beetle, Dermestes lardarius, subfamily Dermestinae, family Dermestidae.
□ As the photographer discovered, these little larder beetles can sneak into a suitcase and be inadvertently transported from one location (in her case, she believes it was a Texas motel room) to another (her house across the country).
Photographed by: Kasey Mangold. Identified by: KnowYourInsects.org. Location: Austin, Texas, and New Hampshire, USA. Date: 12 May, 2016.
Kasey says, “They seem to like the shower. They can fly but don’t do it often.”
Carpet beetle (Attagenus unicolor)
Carpet beetle, likely black carpet beetle, Attagenus unicolor, subfamily Attageninae, family Dermestidae.
□ The tuft of long hairs at the rear end is typical of black carpet beetles. They are common insects in homes, where they find and dine on cereals and other grain-type products.
Photographed by: Megan Hartley. Identified by: KnowYourInsects.org. Location: northern New Jersey, USA. Date: 21 September, 2017.
Megan says, “This guy molted, as you can see the shell.... (It was) in the back of my silverware drawer in a bottle cap.”
Varied carpet beetle (Anthrenus verbasci)
Varied carpet beetle, larva, Anthrenus verbasci, subfamily Megatominae, family Dermestidae.
□ One way to distinguish the larva of a varied carpet beetle from the similar furniture carpet beetle (Anthrenus flavipes or black sarpet beetle (Anthrenus unicolor is to look at the shape of the body. The larva of a varied carpet beetle is wider toward the rear and narrower toward the head. And in case you are not sure where the head is, it is toward the left in this photo.
Photographed by: Jon R. Identified by: KnowYourInsects.org. Location: Herndon, Virginia, USA. Date: 8 October, 2017.
Jon says, “I found it today in my kitchen, near the sink. The insect is 3mm long.... It moves extremely slowly.”
Varied carpet beetle larva (Anthrenus verbasci)
Varied carpet beetle, larva, Anthrenus verbasci, subfamily Megatominae, family Dermestidae.
□ Another feature of the larva of a varied carpet beetle is the thick tuft of brush-like hairs on its back end. The tuft is clearly evident in this excellent photo. They are frequently found in houses.
Photographed by: Don L. Identified by: KnowYourInsects.org. Location: Oklahoma, USA. Date: 17 November, 2017.
Don says, “This little guy is 4 mm long, typically noticed solitary on counter tops, often overlooked as being a piece of fuzz or lint. He may sit motionless for days. When he does move, his speed is almost imperceptible. If disturbed, he freezes, appearing dead. After being left alone, he’ll right himself and begin to move only a short distance (an inch or two) before stopping.”
Varied carpet beetle larva (Anthrenus verbasci)
Varied carpet beetle, Anthrenus verbasci, subfamily Megatominae, family Dermestidae.
□ The quarter illustrates the small size of these pretty little varied carpet beetles. The larvae are shown elsewhere on this page.
Photographed by: Carey Ann Atherton. Identified by: KnowYourInsects.org. Location: Owensboro, Kentucky, USA. Date: 3 April, 2018.
Carey Ann says, “These images were taken at night (around 10 p.m.).”
Varied carpet beetle larva (Anthrenus verbasci)
Varied carpet beetle, Anthrenus verbasci, subfamily Megatominae, family Dermestidae.
□ This photo shows the pair of filmy, membranous wings just peeking out from the rear of this varied carpet beetle. Normally, these membranous wings are hidden beneath the zig-zag patterned forewings (called elytra), which cover most of the beetle’s back.
Photographed by: Will Plemmons. Identified by: KnowYourInsects.org. Location: Kalamazoo, Michigan, USA. Date: 4 May, 2019.
Will described this beetle as about the size of a BB.

Phengodidae, the glowworm beetles

Glowworm beetle (Phengodes plumosa)
Glowworm beetle, male, Phengodes plumosa, subfamily Phengodinae, family Phengodidae.
□ The male glowworm beetles are impressive with those amazing, comb-like (pectinate) antennae. The female, shown elsewhere on this page, looks quite different ... and glows in the dark!
Photographed by: Jill Roberts. Identified by: KnowYourInsects.org. Location: Milledgeville, Georgia, USA. Date: 30 June, 2017.
Jill says, “It is the weirdest bug I’ve ever seen around these parts.” KnowYourInsects.org says, “We love ‘weird’!”
Glowworm beetle (Phengodes spp.)
Glowworm beetle, male, in the genus Phengodes, subfamily Phengodinae, family Phengodidae.
□ The male glowworm beetle lacks the typical, large hardened forewings, called elytra, that cover the membranous flight wings. In the male glowworm beetles, the elytra are very small (difficult to even see in this photograph) so the membranous flight wings are in plain view.
Photographed by: Jordan Ivy. Identified by: KnowYourInsects.org. Location: Texas, USA. Date: 15 July, 2019.
Glowworm beetle (Phengodes spp.)
Glowworm beetle, female or grub, in the genus Phengodes, subfamily Phengodinae, family Phengodidae.
□ The adult female and the grubs of glowworm beetles in this genus (Phengodes) look much alike, so this could be either one. The females are seen more often than the grubs, so this is likely a female. The little red “windows” are ioluminescent in the female, and will glow, which is why they are called glowworms. When they are lit up, some people think they look like the lit windows of passenger railroad cars, so they are sometimes called railroad bugs.
Photographed by: Michelle Hicks. Identified by: KnowYourInsects.org. Location: Charlotte, North Carolina, USA. Date: 31 May, 2019.

Silvanidae, the flat bark or silvanid beetles

Saw-toothed grain beetle (Oryzaephilus surinamensis or Oryzaephilus mercator)
Saw-toothed grain beetle, Oryzaephilus surinamensis or Oryzaephilus mercator, subfamily Silvaninae, family Silvanidae.
□ The saw-toothed grain beetle is a quite common household pest. It feeds on grain or whatever other pantry food it can find, and it is a small insect, so it can get in even the tiniest of places. Note the tiny spikes on its thorax — they help to identify this beetle as one of the two species mentioned.
Photographed by: Laura Vasquez. Identified by: KnowYourInsects.org. Location: central Minnesota, USA. Date: 1 July, 2018.

Meloidae, the blister beetles

Margined Blister Beetle (Epicauta pestifera)
Margined blister beetle, Epicauta pestifer, subfamily Meloinae, family Meloidae.
□ The thorax and each elytra (the hardened forewings that cover its abdomen) of this margined blister beetle have light-colored outlines or margins. This beetle can do some damage to several garden plants, including potatoes and tomatoes.
Photographed by: Anonymous. Identified by: KnowYourInsects.org. Location: Adrian, Michigan, USA. Date: July, 2014.
Blister Beetle, Epicauta spp.
Blister beetle in the genus Epicauta,, possibly the spotted blister beetle Epicauta maculata, subfamily Meloinae, family Meloidae.
□ The spotted blister beetle is pale green, gray, or gray-beige with many small black polka dots. Several species in this genus (Epicauta) look very similar.
Photographed and identified to genus by: Tommy Vick. Identified to tentative species by: KnowYourInsects.org. Location: Fort Davis, Texas, USA. Date: 29 June, 2018.
Yellow-Crescent Blister Beetle (Pyrota insulata )
Yellow-crescent blister beetle, Pyrota insulata , subfamily Meloinae, family Meloidae.
□ The yellow-crescent blister beetle often has thin slashes of orange toward the base of its two elytra (the hardened forewings that cover its back) and a orange spot at the tip of each elytra, but this one is a slightly different form with an orange-encircled spot at the base of each of its elytra, and no separated orange spot at the tip. To see the variety in this species, click here (a Texas Entomology website).
Photographed and identified by: Brenda Kirschner. Nice job on the ID, Brenda! Location: Stamford, Texas, USA. Date: 25 May, 2020.
Nuttall's blister beetle (Lytta nuttalli)
Nuttall’s blister beetle, Lytta nuttalli, subfamily Meloinae, family Meloidae.
Nuttall’s blister beetle is a gorgeous beetle with a metallic head, thorax and abdomen; and purple elytra (the forewings). And it is large — see the photographer’s comment below. This species eats rapeseed, which is a yellow-flowered crop often grown in Canada to make into cooking oil.
Photographed by: April Roch. Identified by:KnowYourInsects.org. Location: near Lloydminster in Alberta, Canada. Date: 28 June, 2019.
April says, “I saw this beautiful beetle in the early evening. It was about 2 inches long (5 cm) and that is not counting the antennae!”
Bronze Blister Beetle (Lytta polita)
Bronze blister beetle, Lytta polita, subfamily Meloinae, family Meloidae.
□ This bronze blister beetle has beautiful shiny bronze elytra (the wings covering its abdomen), and a purple-tinged thoras and head, and black and reddish-orange legs. It is called a blister beetle because it will release some blood (called haemolymph) when it is agitated, and contact with the haemolymph can cause a reaction — non-painful, temporary blisters — in people.
Photographed by: Lisa Nolan. Identified by: KnowYourInsects.org. Location: northern Florida, USA. Date: 30 December, 2019.
Oil beetles mating (Meloe spp.)
Oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
Photographed by: Chris G. Briggs Sr. Identified by: KnowYourInsects.org. Location: northern Muskegon County, Michigan, USA. Date: 5 October, 2015.
Craig says, “A lone one was cutting through a grass blade with short, strong mandibles.”
Oil Beetle (Meloe spp.)
Oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
□ When disturbed, oil beetles release fluid from their joints (as seen here). It is sometimes called “reflexive bleeding.” The fluid is distasteful to potential predators, so it serves a protective function. Another feature of oil beetles is that the thorax is considerably narrower than the abdomen, and also narrower than the head.
Photographed by: Pat (no last name given). Identified by: KnowYourInsects.org. Location: Belding, Michigan, USA. Date: 7 October, 2014.
Oil Beetle (Meloe spp.)
Oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
□ Although it may look from the top view of this oil beetle that the last pair of legs sprouts from the abdomen, all six of its legs arise from the thorax. (This is true of all adult insects.)
Photographed and identified by: Josh Bozarth. Location: Proud Lake Recreation Area, Wixom, Michigan, USA. Date: 31 October, 2018.
Oil Beetle (Meloe impressus)
Oil beetles, mating pair, in the genus Meloe, possibly Meloe impressus, subfamily Meloinae, family Meloidae.
□ The photographer described the larger oil beetle (the female) as being approximately 1.5 inches (3.8 cm) long, and the smaller one (the male) at about 1.25 inches (3.2 cm) long. The size along with the flared antennal segment about halfway down each of his antennae suggests they are the species Meloe impressus. See the photographer’s comments below.
Photographed and identified to genus by: Susan Anderson. Identified to tentative species by: KnowYourInsects.org. Location: Bethesda, Maryland, USA. Date: 25 November, 2018.
Susan found this pair in her garden. She says they “seemed green in sunlight.”
Oil Beetle (Meloe spp.)
Oil beetle, Meloe angusticollis, subfamily Meloinae, family Meloidae.
Photographed by: Alexandra Scheumann, WoodHeaven Photography. Identified by: KnowYourInsects.org. Location: Hurleyville, Sullivan County, New York, USA. Date: 20 October, 2017.
Oil beetle (Meloe proscarabaeus)
Oil Beetle, probably Meloe proscarabaeus, subfamily Meloinae, family Meloidae.
□ This oil beetle is indeed a bright blue color — lovely! Oil beetle experts Carolina Bravo and Mario García-París tentatively identified this oil beetle as the species Meloe proscarabaeus, but Dr. Bravo notes that without a good view of the mesonotum (the middle segment of the thorax), there is also a possibility that it could be the species Meloe violaceus.
Photographed and identified as an oil beetle by: Matthew Rodda. Identified to genus and tentative species by: Carolina Bravo of the Museo Nacional de Ciencias Naturales-CSIC (the National Museum of Natural History of Spain) and Mario García-París of the Spanish National Research Council. Thank you for the identification, Dr. Bravo and Dr. García-París!
Location: Adjara, country of Georgia (between Western Asia and Eastern Europe). Date: 4 March, 2018.
Matthew says, “Found on the ground in a rainforest in Adjara, (country of) Georgia.”
Oil Beetle (Meloe spp.)
Oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
□ The photographer described this oil beetle beautifully: “black with a dashing turquoise sheen and short elytra.” Its body is about 3/4 inches (1.9 cm) long.
□ Males release a noxious fluid from their joints, and that fluid contains cantharidin. Cantharidin had been used historically to make Spanish fly, an aphrodisiac.
Photographed and identified to order by: Victoria Meller. Identified to genus by: KnowYourInsects.org. Location: Kensington Metropark, Milford Township, Michigan, USA. Date: 27 September, 2020.
Blister Beetle (family Meloidae)
Blister beetle, species unknown, family Meloidae.
□ KnowYourInsects.org could determine the species of this striking blister beetle — if you know the genus or species, please let us know!
Photographed by: Ajay Antony. Identified by: KnowYourInsects.org. Location: Tamilnadu, India. Date: 24 May, 2017.
Orange Blister Beetle (Hycleus pustulata or Mylabris pustulata)
Orange blister beetle, Hycleus pustulata, subfamily Meloinae, family Meloidae.
□ The orange blister beetle — and other blister beetles in this family — actually do cause blistering if they are handled. Note: This species is sometimes listed as in the genus Mylabris.
Photographed by: Ajay Antony. Identified by: KnowYourInsects.org. Location: Tamilnadu, India. Date: 24 May, 2017.
Orange Blister Beetle (Hycleus pustulata or Mylabris pustulata)
Orange blister beetle, Hycleus pustulata, subfamily Meloinae, family Meloidae.
□ Notice the jaws and palps on this orange blister beetle. The palps are the small structures just below the jaws (they almost look like little antennae). The palps have sensory receptors on them, so they help the beetle to taste. Note: This species is sometimes listed as in the genus Mylabris.
Photographed by: Shefali Chaudhari. Identified by: KnowYourInsects.org. Location: Gujarat, India. Date: 13 July, 2020.

Oedemeridae, the false blister beetles

Wharf Borer (Nacerdes melanura)
Wharf borer, Nacerdes melanura, subfamily Oedemerinae, family Oedemeridae.
wharf borer larvae (grubs) bore long tunnels in moist, decaying wood, often in wharfs, but anywhere they can find moist wood. The adults only live a week, and they usually emerge all at once.
Photographed and identified to order by: Mattias Lindstedt. Identified to species by: KnowYourInsects.org. Location: southern Spain. Date: 9 June, 2018.
Mattias says, “Length without antennas approx. 2 cm.” That’s a bit less than an inch long.
Flower Beetle (Oedemera nobilis)
Swollen-thighed beetle, also known as a thick-legged flower beetle, female, Oedemera nobilis, subfamily Oedemerinae, family Oedemeridae.
□ One of the features of this swollen-thighed beetle — besides the beautiful metallic blue-green color — is that its elytra (hardened forewings) do not entirely cover the abdomen, as shown in this photo. A similar-looking beetle is the lesser thick-legged flower beetle (Ischnomera cyanea), but it does not have the gap between the elytra.
Photographed by: Bryan Wenham-Baker. Identified by: KnowYourInsects.org. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 1 August, 2018.
Flower Beetle (Oedemera nobilis)
Swollen-thighed beetle, also known as a thick-legged flower beetle, female, Oedemera nobilis, subfamily Oedemerinae, family Oedemeridae.
□ A similar species — Oedemera lurida — of flower beetle also makes its home in the UK. Oedemera lurida is gray-green in color, while the swollen-thighed beetle shown here is more of a brilliant green. As the photographer noted, the swollen-thighed beetle is also sometimes known as false oil beetle.
Photographed by: Bryan Wenham-Baker. Identified by: KnowYourInsects.org. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 17 May, 2020.
Swollen-Thighed Beetle (Oedemera nobilis)
Swollen-thighed beetle, also known as a thick-legged flower beetle, female, Oedemera nobilis, subfamily Oedemerinae, family Oedemeridae.
□ Both the male and female swollen-thighed beetles have metallic bodies, which are usually green, but sometimes blue or purple.
Photographed and identified by: Jean-Louis Metzger. Location: St. Pée-sur-Nivelle, France. Date: 21 May, 2018.
Jean-Louis photographed this beautiful beetle in the garden.
Swollen-Thighed Beetle (Oedemera nobilis)
Swollen-thighed beetles, also known as thick-legged flower beetles, Oedemera nobilis, subfamily Oedemerinae, family Oedemeridae.
□ The male and female swollen-thighed beetle can be distinguished. The male (left photo) has quite-enlarged and swollen-looking femora (femurs) on its hind legs, as well as beefed-up tibiae (the segment behind the femur). The female’s legs are slender, as seen in the right photo.
Photographed and identified by: Jean-Louis Metzger. Location: Oxford, England, UK. Date: 27 May, 2019, for the female; and 29 May, 2019, for the male.

Staphylinidae, the rove beetles

Rove Beetle (Staphylinus caesareus)
Imperial rove beetle, Staphylinus caesareus, subfamily Staphylininae, family Staphylinidae.
□ The imperial rove beetle has reddish-brown elytra, a black abdomen with white markings, and a black scutellum (the triangle at between the front of the elytra). A very similar-looking rove beetle is the species Staphylinus erythropterus. Photographed by: Yodfat. Identified by: KnowYourInsects.org. Location: West Swiss, Europe. Date: 29 March, 2017.
Yodfat says, “I actually saw him on my window, which is in full sun and (on the) second floor above a busy road.”
Rove Beetle (Staphylinus erythropterus)
Rove Beetle, likely Staphylinus erythropterus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ To distinguish two very similar rove beetles — Staphylinus caesarus (previous photo) from Staphylinus erythropterus (next photo), look at the triangle (called the scutellum) between the front of the reddish-brown forewings (which are called elytra). The arrow here shows the scutellum. Staphylinus caesarus has a black scutellum; Staphylinus erythropterus has a light-colored scutellum.
Photographed by: Oliver Davies. Identified by: KnowYourInsects.org. Location: South Wales, UK. Date: 27 August, 2017.
Rove Beetle (Staphylinus erythropterus)
Rove Beetle, likely Staphylinus erythropterus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ A good photo comparison between the two very similar species of rove beetleStaphylinus caesarus and Staphylinus erythropterus is available (the writing is in Italian), by clicking here.

Oliver found this beetle in his dog’s pen.
Devil’s Coach Horse Beetle (Ocypus spp.)
Devil’s coach horse beetle in the genus Ocypus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
Devil’s coach horse beetle: What a wild name! Note the small elytra (hard forewings) that extend a short way down its abdomen. Beneath the elytra are much-folded flight wings. Short elytra are common features of rove beetles.
Photographed and identified by: Neil Harris-Hutchins. Location: Bratton Fleming, North Devon, England. Date: 5 September, 2016.
KnowYourInsects.org says, “Great job on the ID, Neil!”
Devil’s coach horse beetle (Ocypus spp.)
Devil’s coach horse beetle in the genus Ocypus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
Devil’s coach horse beetles will often strut around with their abdomens curled up like this, something that is possible because of the short elytra (hard forewings).
Submitted by: Sandra Cole. Photographed by: Andrew Knight. Identified by: KnowYourInsects.org. Location: Portland, Oregon, USA. Date: 10 October, 2018.
Sandra says, “Large, black, six-legged thing found in waste-water plant.” KnowYourInsects.org says, “Thanks to Sandra Cole for sending in her son Andrew’s photo!
Hairy Rove Beetle (Creophilus maxillosus)
Hairy rove beetle, Creophilus maxillosus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ This hairy rove beetle is an inch (2.5 cm) long. Look closely to see the setae (the hairs) on its abdomen. The short elytra (hard forewings) are also covered with hair, and the membranous hind wings are poking out from beneath them.
Photographed by:Mary Beth Barenborg. Identified by: KnowYourInsects.org. Identification verified by entomologist Frank Carle of Rutgers University. Thank you, Dr. Carle! Location: Trenton, New Jersey, USA. Date: 21 August, 2017.
Mary Beth says she found two in her house — the first was in a clean, plastic mixing bowl sitting on the kitchen counter, and the second was a dinner guest that dropped from the ceiling light fixture “and landed on the center of the table!”
Brown Rove Beetle (Platydracus maculosus)
Brown rove beetle, Platydracus maculosus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ One of the especially interesting things about this photo of a brown rove beetle is that it shows the filmy hind wings peaking out from behind the short, hard forewings (called elytra). This cool beetle was found on the playground of a middle school — specifically Westfield Day School — by classmates Cole and Brian. Thanks to Mrs. De Silva and her whole class!
Photographed by: Shiromi De Silva. Identified by: Dr. Al Newton, curator emeritus, the Field Museum of Natural History in Chicago. Thank you, Dr. Newton! Location: Armonk, New York, USA. Date: 2 November, 2017.

Rove Beetle (Platydracus immaculatus)
Rove beetle, Platydracus immaculatus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ This pretty rove beetle is a mix of reddish-brown, dark brown, yellowish-tan and black. The light-colored spots on its abdomen, along with the red-brown head and elytra (the short wings) help to identify this species.
Photographed by: Shirley Faust. Identified by: KnowYourInsects.org. Location: Andreas, Pennsylvania, USA. Date: 26 September, 2018.
Rove Beetle (Platydracus spp.)
Rove beetle in the genus Platydracus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ This genus name of this rove beetle is Platydracus, which literally means “flat dragon,” and its body is quite flat. This specimen has a large head, short elytra (the pair of forewings that cover about a third of its abdomen), and a red tip on its abdomen.
Photographed by: Mateus Mureb de Mattos Fernandes. Identified by: KnowYourInsects.org. Location: Rio de Janeiro, Brazil. Date: 27 February, 2020.

Brown Rove Beetle (Platydracus maculosus) and Japanese Beetle (Popillia japonica)
Brown rove beetle, Platydracus maculosus, subfamily Staphylininae, family Staphylinidae (the rove beetles).
□ The photographer videotaped a battle between this brown rove beetle and Japanese beetle (Popillia japonica). These are screen grabs from the video. See her comment below.
Photographed and identified as a Japanese Beetle by: Sharon VanLoozenoord. Rove beetle identified by: KnowYourInsects.org. Location: Belmont, Michigan, USA. Date: 14 July, 2018.
Sharon witnessed the fight among some wood chips in her herb garden. On the following day, she reported, “I was in my herb garden again this morning and looked for another ‘fight,’ but I’ll probably never see that again.”
Tachyporus hypnorum
Staphylinid beetle (no common name), Tachyporus hypnorum, subfamily Tachyporinae, family Staphylinidae (the rove beetles).
□ This unusual-looking Staphylinid beetle only measured about 4 mm (0.16 inches) long. Compare that to the devil’s coach horse beetle and imperial rove beetle (pictured elsewhere on this page), which both grow to around 25 mm (1 inch) long.
Photographed by: Ben Dobson, aka The Microscope Man for his microscope-aided photography. Identified by: Mark Telfer. Thank you, Mark! Location: Cambridge, UK. Date: 4 August, 2017.
Ben says, “I found it in on an old log. I’ve used a microscope to photograph (this is a serious hobby).” KnowYourInsects.org says, “Cool hobby!”
Rove Beetle larva (family Staphylinidae)
Rove beetle, larva, family Staphylinidae (the rove beetles).
□ The two spiky, tail-like appendages (called urogomphi) identify this as a beetle larva. Two beetle families have larvae that look almost alike: the rove beetles (Staphylinidae); and the ground beetles (Carabidae). One of the differences between them is in the number of segments in the “shin” (tibia). If there is only one segment, it is a larva of a rove beetle.
Photographed by: Thomas Langhans. See Thomas’s full-size image here. Identified by: KnowYourInsects.org. Location: San Bruno, county of San Mateo, California, USA. Date: 7 February, 2018.
Thomas says, “It was about 22 mm long.”
Rove Beetle larva (subfamily Paederinae)

Photographed by: Stefan Toft Christensen. Identified by: Alexey Solodovnikov of the Biosystematics Department at the Natural History Museum of Denmark. Thank you, Dr. Solodovnikov! Location: Northjutland, Denmark. Date: 2 October, 2018.
Stefan says he found this creature in his house, and believes it came in when he brought his garden plants inside the previous day.

Scarabaeidae, the scarab beetles

Bumble Flower Beetle (Euphoria inda)
Bumble flower beetle,s also known as a bumble flower scarabs or brown fruit chafers, Euphoria inda, subfamily Cetoniinae, family Scarabaeidae.
□ A row of these cute bumble flower beetles! Each is about a half-inch long (1.25 cm). Bumble flower beetles get their common name from their lazy flight — similar to that of a bumble bee. Bumble flower beetles buzz around flowers and rotting fruit, looking for sweet nectar and fermenting fruit juices.
□ Check out this Bumble Flower Beetle’s amazing fur coat in the close-up photo.
Photographed by: Lucy Solar. Identified by: KnowYourInsects.org. Location: near Spokane, Washington, USA. Date: 4 September, 2017.
Lucy says, “Yesterday I discovered a couple of these insects on the outside of my compost tumbler. This afternoon I saw a few more, about eight. Most are not moving much, but a couple were flying around, seemingly finding a spot to rest. It has been very hot during the day — around the 90s (32-35°C) — and it’s been dry. It has also been very smoky, due to the forest fires around. I don’t know if these conditions have anything to do with the presence of these insects or not. I don’t remember having seen them before.”
Bumble Flower Beetle (Euphoria inda)
Bumble flower beetle, also known as a bumble flower scarab or brown fruit chafer, Euphoria inda, subfamily Cetoniinae, family Scarabaeidae.
□ Some bumble flower beetles, like this one, have more black patches on their backs compared to others (as seen elsewhere on this page. When they feel threatened, they give off a strong odor that is sometimes described as smelling like chlorine. The photographer described it as about 0.5 inches (1.25 cm) long.
Photographed and identified by: Gary W. Goodnight. Location: Littleton, Colorado, USA. Date: 20 August, 2020.
Hermit Flower Beetle (Osmoderma eremicola)
Hermit flower beetle, Osmoderma eremicola, subfamily Cetoniinae, family Scarabaeidae.
□ One of the largest beetles in the state of Iowa, where this photo was taken, the hermit flower beetle is more than an inch long. In fact, the photographer put its length at 3.5 cm (1.4 inches). These harmless, but large beetles will fly to lights at night.
Photographed and identified to order by: Violetta. Identified to species by: KnowYourInsects.org. Location: Cherokee, Iowa, USA. Date: 31 July, 2019.
Hermit Flower Beetle (Osmoderma eremicola)
Hermit flower beetle, Osmoderma eremicola, subfamily Cetoniinae, family Scarabaeidae.
□ The hermit flower beetle looks quite similar to the scarab beetle Osmoderma scabra, but the hermit flower beetle has much smoother elytra (the hardened wings covering its abdomen). Its genus name of Osmoderma means scented skin, which refers to the odor this beetle will release when it feels threatened. Some people think the odor smells like leather, so this beetle is sometimes called an odor-of-leather beetle or leather beetle.
Photographed and identified: Daniel DaSilva. Location: Québec, Canada. Date: 29 July, 2020.
Green June Beetle (Cotinis nitida)
Green June beetle, Cotinis nitida, subfamily Cetoniinae, family Scarabaeidae.
□ The green June beetle is very similar in appearance to the closely related green fruit beetle (Cotinis mutabilis), pictured elsewhere on this page. The green June beetle is a species of the eastern United States, whereas the green fruit beetle lives on the other side of the country: in the southwestern United States.
Photographed by: Sheldon L. Boyd. Identified by: Audrey Maran. Thank you, Audrey! Location: Hopewell, Virginia, USA. Date: 25 July, 2014.
Green June Beetle (Cotinis nitida)
Green June beetle, Cotinis nitida, subfamily Cetoniinae, family Scarabaeidae.
□ This is a nice photo of the ventral side (belly) of this green June beetle. Notice that all six legs extend from the thorax. This is true of all insects: the legs (and the wings) are attached to the thorax ... and not the abdomen.
Photographed by: Sheldon L. Boyd. Identified by: Audrey Maran. Thank you, Audrey! Location: Hopewell, Virginia, USA. Date: 25 July, 2014.
Green June Beetle (Cotinis nitida)
Green June beetle, Cotinis nitida, subfamily Cetoniinae, family Scarabaeidae.
□ This green June beetle shows off its lovely green-bronze sheen. Green June beetles are fans of ripe fruit, and can be found on everything from berries to tree fruit.
Photographed by: Mary Bonomo. Identified by: KnowYourInsects.org. Location: Export, near Pittsburgh, Pennsylvania, USA. Date: 6 July, 2018.
Mary says, “Seems like they get flipped on their backs, can’t turn over and die.”
Green Fruit Beetle (Cotinis mutabilis)
Green fruit beetle, also known as a figeater, Cotinis mutabilis, subfamily Cetoniinae, family Scarabaeidae.
Green fruit beetles are sometimes called figeaters because they have a taste for figs, although they’ll eat just about any soft fruit, along with tree sap. The similar-looking and closely related green June beetle (Cotinis nitida) is pictured elsewhere on this page.
□ The larvae are big white grubs that go by the wonderful common name of crawlybacks!
Photographed by: Pat Callahan. Identified by: KnowYourInsects.org. Location: near San Diego, California, USA. Date: 19 September, 2017.
Pat’s wife Peg sent in the photo with a note that this beetle is big! She’s right — Green Fruit Beetles grow to about 1.25 inches (3.2 cm)!
Harlequin Flower Beetle (Gymnetis caseyi)
Harlequin flower beetle, Gymnetis caseyi, subfamily Cetoniinae, family Scarabaeidae.
□ The pattern on this harlequin flower beetle looks like a Rorschach ink blot. This is a typical pattern for this species, but some individuals lack the big black blot and instead only have scattered black speckles.
Photographed by: Michael Toombs. Identified by: KnowYourInsects.org. Location: Fluvanna (southeast of Lubbock), Texas, USA. Date: 1 July, 2018.
Mike says the beetles were “drinking the tree sap from a recently pruned red oak tree” on his farm.
Green Rose Chafers (Cetonia aurata)
Green rose chafers, or simply rose chafers, mating pair, Cetonia aurata, subfamily Cetoniinae, family Scarabaeidae.
□ These beautiful green rose chafers actually come in different colors: metallic green (as shown here), bronze, violet, gray, and bluish-black. They are different from the rose chafers found in North America — they in a different genus (Macrodactylus subspinosus) — shown elsewhere on this page.
Photographed by: Jean-Louis Metzger. Identified by: KnowYourInsects.org. Location: Anduze, in the Languedoc, France. Date: 29 April, 2014.
Jean-Louis says, “ These two beetles — thanks to their striking luminescent green colour — caught my eye and my interest.”
Flower Chafer (Heterorrhina elegans)
Flower chafer, Heterorrhina elegans, subfamily Cetoniinae, family Scarabaeidae.
□ Like these two flower chafers, the males of many species in this family (the scarab beetles) will wrestle — sometimes for access to a female, sometimes over food. These photos clearly show the brilliant, shiny green color of most of the flower chafer’s body, as well as the characteristic red/orange coxa (the “hip”).
Photographed by: K J Westman. Identified by: KnowYourInsects.org. Location: Sri Lanka. Date: 4 October, 2018.
KnowYourInsects.org says, “Great job getting the top and bottom views of this pair, K J!”

Fiddler Beetle, also known as Rose Chafer (Eupoecila australasiae)
Fiddler beetle, also known as rose chafer, Eupoecila australasiae, subfamily Cetoniinae, family Scarabaeidae.
□ The green scroll pattern is reminiscent of a violin, which is what gives this beetle its common name of fiddler beetle. In some individuals, the markings are yellow instead of green.
Photographed by: Kerry Dear. Identified by: KnowYourInsects.org. Location: Northern Beaches, Sydney, Australia. Date: 4 January, 2020.
Kerry says, “With a name like rose chafer, I’m hoping he’s not intent on eating my rose!!” “KnowYourInsects.org says, “Luckilu, the adults actually prefer to munch on flowers of the myrtle family (Myrtaceae) and Eucalypts.”
Maculate Flower Beetle (Gnorimella maculosa)
Maculate flower beetle, Gnorimella maculosa, subfamily Cetoniinae, family Scarabaeidae.
□ This pretty maculate flower beetle is very rarely seen, so it is a wonderful find! The “maculate” part of its name refers to its spots: light-colored speckles on the dark thorax, and dark speckles on the light-colored elytra (the hard wings covering its abdomen). It is sometimes called a Maculated Scarab. Little is known about beetle, which is only a half-inch long.
Photographed by: Mark Shippy. Identified by: KnowYourInsects.org. Location: Okemos, Michigan, USA. Date: 9 March, 2020.
Mark found it on the rug of his family room, and he and his family let it go outside. Great job spotting it and then releasing it, Shippy family!
Garden Chafer (Phyllopertha horticola)
Garden chafer, Phyllopertha horticola, subfamily Rutelinae, family Scarabaeidae.
Garden chafers are often seen munching on flowers. This beetle, which grows to about 1.2 cm (half an inch), has hair-covered, brick-red elytra (forewings), and a pair of spines on the side of each foreleg.
Photographed by: Bryan Wenham-Baker. Identified by: KnowYourInsects.org. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 1 August, 2018.
Oriental beetle (Exomala orientalis)
Oriental beetle, Exomala orientalis, subfamily Rutelinae, family Scarabaeidae.
□ The Oriental beetle is native to Japan. It was first observed in the United States in 1920, when it was seen in Connecticut. It is now found from the northeastern United States to the Great Lakes region.
Photographed by: Elizabeth Boyle. Identified by: KnowYourInsects.org. Location: West Milford, New Jersey, USA. Date: 17 July, 2017.
Elizabeth says, “It’s unbelievable how many strange insects I can find in my neck of the woods.”
Oriental beetle (Exomala orientalis)
Oriental beetle, Exomala orientalis, subfamily Rutelinae, family Scarabaeidae.
□ The Oriental beetle has a pair of dark bars on its thorax. This one has its antennae splayed out (see the photographer’s comment below).
□ Its diet is plant roots, including the roots of lawn grass and vegetable crops.
Photographed by: Sarah McKay-Mertz. Identified by: KnowYourInsects.org. Location: Cape Cod, Massachusetts, USA. Date: 4 July, 2020.

Grapevine Beetle (Pelidnota punctata)
Grapevine beetle, Pelidnota punctata, subfamily Rutelinae, family Scarabaeidae.
□ Compare this individual grapevine beetle from Oklahoma to the other two in this row. This one has more reddish tones, and its legs are quite red. Those in the next two photos — both from the Great Lakes region — are more tan in color and have black legs. Nonetheless, they are the same species.
Photographed and identified by: Randy Sanders. Location: Grove, Oklahoma, USA. Date: 30 June, 2017.
Randy says, “Beetle is sitting on a wooden bench just after storm.”
Grapevine Beetle (Pelidnota punctata)
Grapevine beetle, Pelidnota punctata, subfamily Rutelinae, family Scarabaeidae.
Grapevine beetles are common in the eastern United States and in Ontario, although some extend farther west: to Texas and Oklahoma (as seen in the previous photo). Grapevine Beetles are also sometimes known as spotted tan beetles or spotted Junebugs.
Photographed and identified by: Kelly McKinne (@gonzonaturalist). Location: northern Ohio, USA. Date: July, 2016.
Grapevine Beetle (Pelidnota punctata)
Grapevine beetle, Pelidnota punctata, subfamily Rutelinae, family Scarabaeidae.
Grapevine beetles mate at night — under cover of darkness — and the females lay their eggs in the summertime. The eggs hatch into grubs that live underground until the following spring, when they emerge as adults.
Photographed and identified by: Judy Firestone. Location: Oak Park, Oakland County, Michigan, USA. Date: 13 July, 2013.
Grapevine Beetle (Pelidnota punctata)

□ These two photos show a grapevine beetle with its elytra (forewings) spread, and the dark-brown hind wings and abdomen visible; and the underside. Be sure to check out the photographer’s comments below :-).
Photographed and identified by: Kyle Lengerich. Location: Greenwood, Indiana, USA. Date: 26 July, 2019.
Kyle says, “So, I was out picking hops to make a sachet for the wife, and this thing fell out onto my bare foot. I won’t tell you what I yelled at the top of my lungs, but needless to say it startled me.”
Japanese beetle (Popillia japonica)
Japanese beetle, Popillia japonica, subfamily Rutelinae, family Scarabaeidae.
□ The Japanese beetle is native to Japan — surprise ;-) — and it was first identified in the northeastern United States, specifically New Jersey, in 1916. See the full story here. It has since spread far and wide, and is now considered a huge pest in the United States, where it eats all kinds of garden plants as well as the roots of grass.
Photographed and identified by: Leslie Mertz. Location: Otsego Township (near Gaylord), Michigan, USA. Date: 18 July, 2017.
Leslie says, “I never realized that the white spots along the sides and back were little tufts of hair.”
Japanese beetle (Popillia japonica)

Goldsmith Beetle (Cotalpa lanigera)
Goldsmith beetle, Cotalpa lanigera), subfamily Rutelinae, family Scarabaeidae.
□ Considered uncommon, goldsmith beetles have no markings on their backs, except for dozens of tiny punctures on their elytra. A close look reveals that the head and thorax are a greenish-yellow while the elytra are more of a gray-tan hue. Adults munch on the leaves of oaks and a variety of other trees, while the grubs favor rotting wood.
Photographed and identified by: Leslie Mertz. Location: Gaylord, Michigan, USA. Date: 30 May, 2018.
Leslie says, “I found this beetle next to a small wooded area. I had never seen this species there before and have never seen another since.”

Rose chafers (Macrodactylus subspinosus)
Rose chafers, Macrodactylus subspinosus, subfamily Melolonthinae, family Scarabaeidae.
□ Adult rose chafers eat a lot of things from flower blossoms to fruits (as seen here), and also tree leaves (as shown in the next photo). On leaves, they eat the tissue and leave behind the veins — damage that is known as skeletonizing. Fortunately the adults are only out for about 3 weeks or so in Michigan, which is where this photo was taken. Then the adults lay eggs and die. But they do reappear the following year.
Photographed by: Diane P. Kraus. Identified by: KnowYourInsects.org. Location: Glen Arbor, Michigan, USA. Date: 10 June, 2016.
Diane says, “Wild iris blooms covered with them!”

Rose chafers will frequently sit on flowers with one or more legs extended, as seen here.
Photographed and identified by: Leslie Mertz. Location: Markey Township, Roscommon County, Michigan, USA. Date: 4 August, 2019.
Leslie says, “There were probably a couple of dozen rose chafers visiting the oxeye daisies in a small garden, where I took these photos.”
Common Cockchafer (Melolontha melolontha)
Common cockchafer, also known as a Maybug or Doodlebug, Melolontha melolontha, subfamily Melolonthinae, family Scarabaeidae.
□ The common cockchafer has considerable tawny fuzz on its thorax and head, and reddish-brown elytra (the forewings covering its back). To tell a male from a female, count the number of plates on each antenna (see closeup at right): males have seven; females have six. One of its hind wings (the flight wings) is peeking out at the rear from beneath the elytra.
□ Common Cockchafers are rather clumsy beetles — slow-walking and when they fly, often plowing into windows.
Photographed by: James Youngson. Identified by: KnowYourInsects.org. Location: Wirral, England, UK. Date: 20 May, 2020.
Common Cockchafer (Melolontha melolontha)
Common cockchafer, also known as a Doodlebug or Maybug, Melolontha melolontha, subfamily Melolonthinae, family Scarabaeidae.

Lucanidae, the stag beetles

European Stag Beetle (Lucanas cervus)
European stag beetle, male, Lucanas cervus, subfamily Lucaninae, family Lucanidae.
□ The male European stag beetle (shown here) has gigantic jaws that look almost like a pair of antlers, and in fact, that is the origin of the “stag” portion of the name – they look like the antlers of a male deer, also known as a stag. The male’s jaws are big, but weak, and he cannot bite very hard at all. The female has much, much smaller jaws, but they are considerably stronger and she can deliver quite a painful bite.
□ The size of this species varies widely from one geographic region to another, and in some places it grows to be about 5 cm (2 inches) long!

Antelope Beetle (Dorcus parallelus)
Antelope beetle, female, Dorcus parallelus, subfamily Lucaninae, family Lucanidae.
Antelope beetles are drawn to lights in the evening. The rest of the time, they hang out in rotting wood, especially old tree stumps. Depending on the light, they may look very dark brown, dark purplish brown or even black. The jaws help distinguish the male from the female (the female is shown here). In the male, the jaws have an extra projection (called a horn) that points inward from each mandible.

Reddish Brown Stag Beetle (Lucanus capreolus)
Reddish brown stag beetle, Lucanus capreolus, subfamily Lucaninae, family Lucanidae.
□ Besides the overall body color and large jaws, one of the characteristics of the reddish brown stag beetle is its bicolored legs — the femur is orangish-tan and the rest of each leg is reddish-brown.
Photographed by: Tony L. Identified by: KnowYourInsects.org. Location: central New Jersey, USA. Date: 15 July, 2017.
Reddish Brown Stag Beetle (Lucanus capreolus)
Reddish brown stag beetle, female, Lucanus capreolus, subfamily Lucaninae, family Lucanidae.
□ Although they are sometimes spotted during the day, reddish brown stag beetles are mostly active at night, and are often seen on porches or decks where they are attracted to lights.
Photographed by: McKinley Sutterfield. Identified by: KnowYourInsects.org. Location: Craig Park, Greenwood, Indiana, USA. Date: 18 August, 2017.
Says 10-year-old McKinley, “It was being very lazy for being at the playground.”
Reddish Brown Stag Beetle (Lucanus capreolus)
Reddish brown stag beetle, male, Lucanus capreolus, subfamily Lucaninae, family Lucanidae.
□ The male reddish brown stag beetles have large jaws like this, and will fight one another for access to females for mating — but by wrestling rather than biting — until one gives up and leaves. Although the jaws look formidable, they are not aggressive and their bite (only delivered in defense) isn’t much more than a soft nip.
Photographed by: Jeff Andrade. Identified by: KnowYourInsects.org. Location: Portage Lakes, south of Akron Ohio. Date: 4 July, 2019.
Jeff says, “Found it on the floor of my covered back porch.”

Dytiscidae, the predaceous diving beetles

Predaceous Diving Beetle (Cybister fimbriolatus)
Predaceous diving beetle, also known as a Giant Diving Beetle, Cybister fimbriolatus, subfamily Dytiscinae, family Dytiscidae.
Predaceous diving beetles spend much of their lives in the water of ponds and lakes, but they can fly and will often head for streetlights or other lights on land. As noted by the photographer (see below), this one was indeed spotted on land.
Photographed by: Brianna Sutterfield. Identified to family by: Mark Stephens, 2016 Conservation Educator of the Year. Mark runs the wonderful Project F.I.S.H. program in Michigan. Identified to species by: KnowYourInsects.org. Location: Mount Pleasant, Michigan, USA. Date: 27 February, 2018.
Brianna says, “I found this big guy in a parking lot tonight! He was at least an inch and a half long and about an inch wide!”
Predaceous Diving Beetle (Cybister fimbriolatus)
Predaceous diving beetle, also known as a Giant Diving Beetle, Cybister fimbriolatus, subfamily Dytiscinae, family Dytiscidae.
Predaceous diving beetles are quite large: The photographer estimated it at about 1.5 inches (3.8 cm) long. The silhouette and the light-brown border help identify it.
Photographed by: Shawn McComb. Identified by: KnowYourInsects.org. Location: in Kalamazoo, Michigan, USA. Date: 6 April, 2020.

Add your photo here! Water Tiger (Dytiscus spp.)
Water Tiger, likely in the genus Dytiscus, subfamily Dytiscinae, family Dytiscidae.
□ The water tiger is the generic name for the larva of a predaceous diving beetle. It is a fierce predator with its sharp and strong jaws, which work well to attack and subdue prey. According to the photographer, the local people in Odisha, India, call them hardabhanga, which he said translates to “bone breaker,” so named because their bite is so painful (see the comments below).
Photographed and identified to common name by: Skrahim bakas. Identified to genus by: KnowYourInsects.org. Location: Odisha, India. Date: 31 July, 2018.
Skrahim says, “I found them in a muddy field where farmers are ready to plant paddy crops. Generally this insect has a shrimp-like body structure, and the mouth is like a centipede’s. And it is venomous, equal to scorpion.”

Mordellidae, the pintail beetles or tumbling flower beetles

Tumbling Flower Beetle, (Mordella spp.)
Tumbling flower beetle in the genus Mordella, subfamily Mordellinae, family Mordellidae.
□ This is a close-up of one of a pair of tumbling flower beetles the photographer found on a Queen Anne’s lace plant. Queen Anne’s lace is also known as wild carrot. See the comment below.
Photographed by: Ed Hendrickson. Identified to genus by: entomologist Enrico Ruzzier of the Natural History Museum in London, UK. Location: North Carolina, USA. Date: 5 May, 2018.

Elateridae, the click beetles

Eyed Click Beetle (Alaus oculatus)
Eyed click beetle, Alaus oculatus, subfamily Agrypninae, family Elateridae.
□ When the eyed click beetle has its legs pulled in and out of sight, this large beetle looks more like a fishing lure than a living insect.
Photographed and identified by: Keith Grix. Location: Hadley, Michigan, USA. Date: 1 June, 2014.
Eyed Click Beetle (Alaus oculatus)
Eyed click beetle, Alaus oculatus, subfamily Agrypninae, family Elateridae.
□ The “click” part of the eyed click beetle’s name refers to the ability of these beetles to jump due to the presence of a hinge mechanism on their ventral (belly) side. When this mechanism releases, the beetle pops off the ground. If you’re holding one when it clicks, it can be a little startling!
Photographed and identified by: Leslie Mertz. Location: Kalkaska County, Michigan, USA. Date: 12 July, 2011.
Eyed Click Beetle (Alaus oculatus)
Eyed click beetle, Alaus oculatus, subfamily Agrypninae, family Elateridae.
□ The “eyed” part of the eyed click beetle’s name refers to the two big black spots on the thorax. They may look like eyes — and the spots are even called “eyespots” but the spots are just colored spots. Their actual eyes are much smaller and located forward on the head.
Photographed by: Earl McKay. Location: Union, Michigan, USA. Date: 19 June, 2016.
Earl says, “Caught this insect, have never seen one like it in my area, ever!”
Eyed Click Beetle (Alaus oculatus)
Eyed click beetle, Alaus oculatus, subfamily Agrypninae, family Elateridae.

Add your photo here! Texas Click Beetle (Alaus lusciosus)
Texas click beetle, Alaus lusciosus, subfamily Agrypninae, family Elateridae.
□ This nice photo of a Texas click beetle shows the characteristic yellowish flush next to the false eyes on its pronotum. The photo also includes a second, smaller creature in the shot. It’s a Pillbug, which is a crustacean, so the Pillbug is more closely related to a lobster than it is to an insect. Seven-year-old Noah spotted this pair in a dead tree (great job, Noah!), and his mom took the photo.
Spotted by: Noah Louvat. Photographed and identified to genus by: Elizabeth Louvat. (Good work on the identification, Elizabeth!) Identified to species by: KnowYourInsects.org. Location: Central Texas, USA. Date: 21 April, 2019.
Western Eyed Click Beetle (Alaus melanops)
Western eyed click beetles, mating pair, Alaus melanops, subfamily Agrypninae, family Elateridae.
□ This photo shows a mating pair of western eyed click beetles. Some people call click beetles “skip jacks” or “snapping beetles” for the snapping noise they make as they leap or skip into the air to avoid predators.
Photographed and identified by: Nancy James. Location: Coeur d'Alene, Idaho (about 100 miles south of the Canadian border, USA. Date: 21 April, 2019.
Nancy found this pair in her driveway.
Flat Wireworm Beetle (Aeolus mellillus)
Flat wireworm beetle, Aeolus mellillus, subfamily Agrypninae, family Elateridae.
□ It’s called a flat wireworm beetle in reference to the larva, which looks like a flat, soft, yellowish grub. Its flatness separated the grub from similar grubs of related species.
Photographed by: Chris M. Identified by: KnowYourInsects.org. Location: Peoria Heights, Illinois, USA. Date: 29 August, 2016.
After learning it is a type of click beetle, Chris says, “It made an amazing jump off my hand, and I think I do recall hearing a click or pop sound.”
Flat Wireworm Beetle (Aeolus mellillus)
Flat wireworm beetle, Aeolus mellillus, subfamily Agrypninae, family Elateridae.
□ The flat wireworm beetle goes through its entire life cycle — egg to larva/grub to pupa to adult in one year. Related beetles typically take two to four years. It is considered an agricultural pest, especially in fields that have been recently plowed.
Photographed by: John Craig. Identified by: KnowYourInsects.org. Location: central Indiana, USA. Date: 19 May, 2020.
John says it was tiny. Indeed, adult Flat Wireworms only get to by about 8mm (less than 1/3 inch) in length.
Flat Wireworm Beetle (Aeolus mellillus)
Flat wireworm beetle, Aeolus mellillus, subfamily Agrypninae, family Elateridae.
□ Entomologist Goerge M. Stirrett named this the flat wireworm in a journal article back in 1936. Dr. Stirrett described the adult as “having four darker elytral spots (the elytra are the pair of hardened wings that cover its back) and a dark spot of the same color upon the thorax” and the larva/grub as flat, small and light yellow.
Photographed by: Brooke Keaton. Identified by: KnowYourInsects.org. Location: Charlotte, North Carolina, USA. Date: 10 June 2020.
Brooke says, “I woke up with it crawling on me this morning.”
Large Brown Click Beetle (Orthostethus spp.)
Click beetle in the genus Orthostethus, subfamily Elaterinae, family Elateridae.
□ One defensive mechanism of click beetles is to play dead, as the photographer describes below. Another is to fling themselves into the air, using the latch mechanism on their underside. A characteristic of this genus is the series of sharp points on the outside-rear edges of the pronotum (the shield-like covering on the thorax).
Photographed by: Debbie Miranda. Identified by: KnowYourInsects.org. Location: Warren, Rhode Island, USA. Date: 13 July, 2019.
Debbie says, “I saw it on my desk upside down. I moved it. I thought it was dead. I flipped it over to take a pic and after a couple minutes, it started walking.”
Glowing Click Beetle or Cocuyo (Ignelater havaniensis)
Glowing click beetle, also known as a cocuyo, Ignelater havaniensis, subfamily Agrypninae, family Elateridae.
□ The glowing click beetle is known for the two bioluminescent spots on its elytra (the forewings covering its back). The spots glow freen at night. Another species (Deilelater physoderus) is also called a glowing click beetle or gold spot click beetle. By comparison, Deilelater physoderus is a bit smaller at 0.6-0.7 inches (1.5–2.0 cm) long, compared to Ignelater havaniensis, which is 1-1.2 inches (2.5–3.0 cm) long; it has noticeable ridges on its elytra, compared to smoother elytra in Ignelater havaniensis; and lacks the tiny spines that Ignelater havaniensis has on the rear end of its elytra (barely visible in the photo at right.

Sri Lankan Weevil (Myllocerus undecimpustulatus undatus)
Sri Lankan weevil, Myllocerus undecimpustulatus undatus, subfamily Entiminae, family Curculionidae.
□ This Sri Lankan weevil made its way from Sri Lanka to Florida in 2000, and now it is in about half the counties in Florida, mostly the southern half of the state. It looks almost identical to another weevil called the Little Leaf Notcher (Artipus floridanus), which is native to Florida and the Caribbean. Two of the features that set the Sri Lankan Weevil apart are a slightly yellowish head (difficult to see here) and spines on its femur (noted with the yellow arrow).

Katherine says, “Your wonderful website helped me identity a bug that flew through my window today.” KnowYourInsects.org says, “Wonderful! And great job with the identification, Kath!”
Red Palm Weevil (Rhynchophorus ferrugineus)
Red palm weevil, Rhynchophorus ferrugineus, subfamily Dryophthorinae, family Curculionidae.
□ The red palm weevil is native to southern Asia and over to Papua New Guinea and nearby islands, but has spread to other warm climates as well. For instance, it was first reported in southern California in 2010, but after a concerted effort to find and get rid of it, it was declared eradicated in January 2015.
Photographed and identified by: Katherine Toumbourou. Location: Nicosia, Cyprus. Date: 16 May, 2018.
Katherine says, “They’re a real problem both here and in the Middle East, and are classified as pests.”
Red Palm Weevil (Rhynchophorus ferrugineus)
Red palm weevil, Rhynchophorus ferrugineus, subfamily Dryophthorinae, family Curculionidae.
□ These photos show the top and bottom views of this red palm weevil. Some individuals have fewer spots on the thorax, as shown in the other photos of this species on this page. Notice the tiny red balls up near the head in the bottom view — Those are phoretic mites (related to ticks and spiders) that use insects like buses: They climb aboard, take a ride, and hop off.
Photographed and identified to order by: Yanni Petropoulos. Location: On the mainland, Southwest Greece. Date: 19 April, 2020.
Yanni says, “Took a photo of this beautiful insect today (it visited our balcony). When I checked on it again after 5 minutes, it was upside down and pretending dead! I flipped it and after a while started moving again.”
Banana Stem Weevil (Odoiporus longicollis)
Banana stem weevil, Odoiporus longicollis, subfamily Dryophthorinae, family Curculionidae.
□ As adults, the banana stem weevil may be 2.3-3.9 cm (1-1.5 inches) long, so they have quite a size range. They are pests of bananas, as well as plantains.

Rice Weevil (Sitophilus oryzae)
Rice weevil, Sitophilus oryzae, subfamily Dryophthorinae, family Curculionidae.
Rice weevils infest rice as well as several other grains, such as wheat and corn, and is sometimes known by the name lesser grain weevil. And be sure to check out the photographer’s comment below.
Photographed by: Jim Coolbaugh, a retired U.S. Navy infectious disease research microbiologist. Identified by: KnowYourInsects.org. Location: in the sea near Malaysia. Date: 24 November, 2017.
Jim says, “We are on a sailboat in Malaysia, and have an infestation of these insects. They are about 2mm long, and they fly.” In an update, Jim says they found the source of the infestation: “They are coming from some stored, and thought-sealed pasta.... Out you weevils!”
Agave or Sisal Weevil (Scyphophorus acupunctatus)
Sisal weevil, sometimes called an agave weevil, Scyphophorus acupunctatus, subfamily Dryophthorinae, family Curculionidae.
□ This weevil is known as a sisal weevil because its host plant is a type of agave called sisal (Agave sisalana), which is often used to make twine or rope.
□ Note: This is now listed as part of the subfamily Dryophthorinae, which falls under the family Curculionidae. At one time, the Dryophthorinae was listed as its own family: Dryophthoridae.
Photographed by: Carlo Castoro. Identified by: KnowYourInsects.org. Location: St. Thomas, U.S. Virgin Islands. Date: 7 January, 2018.
Billbug (Sphenophorus latinasus)
Billbug in the genus Sphenophorus, possibly Sphenophorus latinasus, subfamily Dryophthorinae, family Curculionidae.
□ This weevil is known as a billbug, named for its long snout or “bill”. Little has been written about Sphenophorus latinasus, which suggests that it has not been found to be a major agricultural or landscaping pest (the squeaky wheel gets the grease!). More attention has been paid to a related species, called a bluegrass billbug (Sphenophorus parvulus) that is a pest in lawns.
Photographed and identified to family by: Marv Goldberg. Identified to species by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 25 May, 2020.
Snout Weevil (Neoerethistes spp.)
Snout weevil in the genus Neoerethistes, subfamily Molytinae, family Curculionidae.
□ Check out the curved snout on this handsome snout weevil. The tan-colored speckles on its back almost look like it was sprinkled with sticky sand.
Photographed by: Donna Sánchez. Identified to genus by: Macotulio Soto-Hernández, Instituto de Ecología, México. Location: Malinalco, México. Date: 9 July, 2017.
Snout Weevil (Conotrachelus posticatus)

Photographed by: Yanni Petropoulos. Identified by: KnowYourInsects.org. Location: mainland of southwestern Greece. Date: 30 April, 2020.

Brentidae, the primitive weevils

Brentid weevil (Arrhenodes minutus)
Brentid weevil, also known as an oak timberworm weevil, male, Arrhenodes minutus, subfamily Brentinae, family Brentidae.
□ To tell male from female in brentid weevils, look at the mouthparts. This male has a rather robust pair of jaws, whereas the female has an elongate, tube-shaped beak.
Photographed by: Ray Chin. Identified by: KnowYourInsects.org. Location: Toronto, Canada. Date: 7 January, 2018.
Brentid weevil (Arrhenodes minutus)
Brentid weevil, also known as an Oak Timberworm Weevil, male, Arrhenodes minutus, subfamily Brentinae, family Brentidae.
□ The brentid weevil is sometimes called an oak timberworm weevil because its larvae look rather like worms and will bore into wood, especially oak.
Photographed by: Mary Freelove. Identified by: entomologist E. Richard Hoebeke with the University of Georgia Extension. Thank you, Rick! Location: northern Georgia, USA. Date: 30 April, 2016.
Brentid weevil (Arrhenodes minutus)
Brentid weevil, also known as an oak timberworm weevil, male, Arrhenodes minutus, subfamily Brentinae, family Brentidae.
□ This brentid weevil has a little less of the yellow markings on its elytra (the hardened wings covering its abdomen) than is typical of this species.
Photographed and identified to order by: Jaymie Miller. Identified to species by: KnowYourInsects.org. Location: middle Tennessee, USA. Date: 19 May, 2019.

Attelabidae, the leaf-rolling weevils

Hazel Leaf-Roller (Apoderus coryli)
Hazel leaf-roller, Apoderus coryli, subfamily Attelabinae, family Attelabidae.
□ The hazel leaf-roller/b> is so named because the young live inside rolled-up leaves of hazel trees and shrubs.
Photographed and identified by: Bryan Wenham-Baker. See his full-size image here. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 29 July, 2018.
Leaf-rolling weevil (Homoeolabus analis)
Leaf-rolling weevil, Homoeolabus analis, subfamily Attelabinae, family Attelabidae.
□ The female of this leaf-rolling weevil and other species in this family lay their eggs on a leaf, and roll up the leaf (like rolling up a rug) with the eggs inside. This protects the eggs as well as the larvae that later hatch from the eggs.
Photographed by: Joan Smith. Identified by: KnowYourInsects.org. Location: Tampa, Florida, USA. Date: 9 June, 2017.

Lycidae, the net-winged beetles

End band net-wing beetle (Calopteron terminale)
End band net-wing beetle, Calopteron terminale, subfamily Lycinae, family Lycidae.
□ With its forewings up and out of the way, the hind wings of this end band net-wing beetle become visible.
Photographed by: Claire M.Montgomery. Identified by: KnowYourInsects.org. Location: southern Louisiana, USA. Date: 1 September, 2014.
End Band Net-Wing Beetle (Calopteron terminale)
End band net-wing beetle, Calopteron terminale, subfamily Lycinae, family Lycidae.
□ The end band net-wing beetle usually only has one band on the end of the elytra (the forewings covering the abdomen), as shown here. Similar-looking species include Calopteron discrepans and Calopteron reticulatum — both known as banded net-wing beetles — that typically (although not always, as shown elsewhere on this page) have an additional black band running through the center of their elytra.
Photographed by: Claire M.Montgomery. Identified by: KnowYourInsects.org. Location: southern Louisiana, USA. Date: 1 September, 2014.

Banded Net-Wing Beetle (Calopteron reticulatum)
Banded net-wing beetle, Calopteron reticulatum, subfamily Lycinae, family Lycidae.
□ There are two species of banded net-wing beetleCalopteron discrepans and Calopteron reticulatum — both of which have a black band across the middle of each of the two forewings (called elytra). The difference between the two is that Calopteron discrepans has a band that is the same width all the way across the wing, while Calopteron reticulatum has a band that is wider where the two elytra meet and tapers off toward the outer sides. This photo seems to show the band tapering, so it is identified as Calopteron reticulatum.
Photographed by: Jim Hartzel. Identified by: KnowYourInsects.org. Location: Burke, Virginia, USA. Date: 11 July, 2018.
Banded Net-Wing Beetle (Calopteron reticulatum)
Banded net-wing beetle, Calopteron reticulatum, subfamily Lycinae, family Lycidae.
□ This banded net-wing beetle lacks the second black band, which occurs in some individuals. This makes it look like the end-band net-wing beetle pictured elsewhere on this page, but the banded net-wing beetle can be distinguished by the smooth edge on its forewings (elytra) and the varying heights to the ridges on the elytra, which can be seen in this photo.
Photographed by: J. Graham. Identified by: KnowYourInsects.org. Location: Noble County, Indiana, USA. Date: 12 August, 2019.
Net-Winged Beetle (Thonalmus chevrolati)
Net-wing beetle, Thonalmus chevrolati, subfamily Lycinae, family Lycidae.
□ These two photos show both pairs of wings on this net-wing beetle. The forewings (called elytra) are stiffer and bicolored, with the rear half of each forewing having a blue or green metallic sheen depending on how the light strikes them. The hindwings, which are used for flight, are membranous.
Photographed by: Juraj Bajgar. Submitted by: Clara Bajgar. Identified by: KnowYourInsects.org. Location: San Juan, Puerto Rico. Date: 30 November, 2018.
Clara says that Juraj caught this pretty beetle, which was 1.3 cm (a half inch) long in flight. She adds, “The bug posed for the picture and flew away.”

Zopheridae, the ironclad beetles and the cylindrical bark beetles

Southwestern Ironclad Beetle (Zopherus nodulosus)
Southwestern ironclad beetle, Zopherus nodulosus, subfamily Zopherinae, family Zopheridae.
□ If they are touched or feel threatened, southwestern ironclad beetles will draw in their legs and play dead. They are quite impressive beetles in color and size, and can reach about 2 inches (5 cm) long.
Photographed by: Cedia Miller. Identified by: KnowYourInsects.org. Location: Unknown. Date: 2 May, 2016.

Flat-Headed Pine Borer (Chalcophora mariana)
Flat-headed pine borer, Chalcophora massiliensis, subfamily Chrysochroinae, family Buprestidae.
□ One of the metallic wood-boring beetles (also called jewel beetles), the flat-headed pine borer is shiny with a pinkish or copper-colored tint, and has somewhat parallel, black striping down its back. It mainly eats rotting wood.
□ This species has gone through some changes in its scientific name, so it is sometimes listed by its former name of Chalcophora mariana or Chalcophora mariana massiliensis.
Photographed by: Julie Lathan. Identified by: KnowYourInsects.org. Location: central Italy. Date: 1 July, 2019.
Pink-Faced Buprestis (Buprestis lyrata)
Jewel beetle, sometimes called a pink-faced jewel beetle, Buprestis lyrata, subfamily Buprestinae, family Buprestidae.
□ This jewel beetle is sometimes called a pink-faced jewel beetle because of the pinkish or orangish blush shown here. Usually, however, the face is not seen. It is typically found on a dead or dying Douglas fir or other pine trees, so it helps with forest regeneration.
Photographed by: Linda Evans Thörnqvist. Identified by: KnowYourInsects.org. Location: Crystal Lake, Oregon, USA. Date: 16 August, 2019.
Linda says, “We saw numerous of these beetles on a tree trunk,” which she later identified as a pine tree trunk.
Red-Legged Buprestis (Buprestis rufipes)
Red-legged buprestis, Buprestis rufipes, subfamily Buprestinae, family Buprestidae.
□The red-legged buprestis has characteristic yellow markings and, of course, red legs! The photo at right shows the beetle with its forewings partially open, displaying the membranous hind wings beneath them. The larvae (grubs) of this species tunnel under the bark in dead or dying hardwood trees.
Photographed and identified to order by: April Christie. Identified to species by: KnowYourInsects.org. Location: Chalfont, Pennsylvania, USA. Date: 11 April, 2019.

Ladybug (Exochomus childreni)
“Minilady” ladybug, Exochomus childreni, subfamily Chilocorinae, family Coccinellidae.
□ This species of ladybug has no official common name, so the photographer named it the “minilady”. He described it as “small enough to be on an aphid’s dinner plate” (see his comment below). It has a black head and thorax, and dark orange to brown elytra (the hardened forewings covering its back) with black blotches on the ends and often black blotches toward the front of its elytra, as seen here.
Photographed and identified to family by: Marv Goldberg. Identified to species by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 25 May, 2020.
Marv says, “This huge beast was about 1/8 inch (3 mm). I wasn’t even sure it was an insect, so I had to photograph it.”
Subvittate Ladybug (Myzia subvittata)
Subvittate ladybug, Myzia subvittata, subfamily Coccinellinae, family Coccinellidae (the ladybugs or ladybird beetles)
□ Some subvittate ladybugs tend to be more yellow (like this one) and others are more orange, and the amount of black streaking also varies quite a bit, but they all have two white blotches on the thorax, and most have the two white smears in the center of the back just behind the thorax. 
Photographed by: Carole Martens. Identified by: KnowYourInsects.org. Location: Whistler, British Columbia, Canada. Date: 28 July, 2020.
Eastern 10-Spotted Ladybird Beetle (Bothrocalvia pupillata)
Eastern 10-Spotted ladybird beetle, larva, Bothrocalvia pupillata, subfamily Coccinellinae, family Coccinellidae.
□ The eastern 10-spotted ladybird beetle is a different species from the 10-spot ladybird beetle (Adalia decempunctata) pictured elsewhere on this page. This larva of an eastern 10-spotted ladybird beetle has a distinctive pattern of large and small black spots on a lighter-colored background. The background may be white (as seen here), orange, yellow or a combination of white, orange and/or yellow.
□ The eastern 10-spotted ladybird beetle is a native of Hong Kong, but has been intentionally introduced to Hawaii, where this photo was taken, to combat plant lice.
Photographed by: Christian Moratin. Identified by: KnowYourInsects.org. Location: Heeia, Oahu, Hawaii, USA. Date: 26 May, 2020.
Seven-Spot Ladybird Beetle (Coccinella septempunctata)
Seven-spot ladybird beetle/ladybug, larva Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ The seven-spot ladybird beetle does indeed have seven spots: three smaller spots on each of the two forewings (or elytra) and one larger one that spreads onto the front of both elytra (between the two white spots). This is quite a common species in Europe.
Photographed and identified by: Bryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: unknown.
Seven-Spot Ladybird Beetle (Coccinella septempunctata)
Seven-spot ladybird beetle/ladybug, Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ This head-on view of the seven-spot ladybug (called a ladybird beetle in the UK) shows the pair of small white dots on its head, the larger white spots on either side of its pronotum (the shield that covers the thorax), and the pair of white spots just behind the pronotum.
Photographed by: Thomas Langhans. See Thomas’s full-size image here Location: San Bruno, county of San Mateo, California, USA. Date: 4 November, 2018.
Seven-Spot Ladybird Beetle (Coccinella septempunctata)
Seven-spot ladybird beetle/ladybug, larva, Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ The larva of the seven-spot ladybug can be distinguished from other ladybug larvae by the red markings on its abdomen. It has no red markings past the fourth abdominal segment (abdominal segments are noted as A1, A2, A3, etc.; the three segments of the thorax are labeled as T1, T2 and T3).
□ The seven-spot ladybug has such a hunger for aphids that it has been introduced multiple times in the United States (where this photo was taken).
Photographed by: Thomas Langhans. See Thomas’s original, full-size image here Location: San Bruno, county of San Mateo, California, USA. Date: 12 March, 2018.
Seven-Spot Ladybird Beetle (Coccinella septempunctata)
Seven-spot ladybird beetle/ladybug, larva, Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.

□ Often, three-banded ladybugs are orange with black bands that are outlined in yellow, but sometimes (as in this one) they are yellow with black bands.
Photographed and identified by: Leslie Mertz. Location: Houghton Lake, Roscommon County, Michigan, USA. Date: 7 July, 2017.
Leslie says, “Such a pretty little ladybug!”
15-spotted ladybug (Anatis labiculata)
15-spotted ladybug/ladybird beetle), Anatis labiculata, family Coccinellidae.
□ This is the typical color and pattern of the 15-spotted ladybug: 15 black spots on a light-gray (sometimes orangish) background with the orange line down the middle of the back. The following photos show how the coloration darkens with age.
Photographed by: Denise Rulason. Identified by: KnowYourInsects.org. Location: Interlochen, Michigan, USA. Date: 23 June, 2018.
15-spotted ladybug (Anatis labiculata)
15-spotted ladybug/ladybird beetle), Anatis labiculata, family Coccinellidae.
□ Typically, the 15-spotted ladybug indeed has 15 black spots on a light-gray to orange background. As they age, however, they sometimes become quite dark, like this one, although the black spots are still visible.

□ This is another older 15-spotted ladybug with even darker coloration than the previous photo.
Photographed and identified by: Leslie Mertz. Location: Houghton Lake, Roscommon County, Michigan, USA. Date: 7 July, 2017.
Leslie says, “I met a woman who told me she was seeing ticks all over the place, and it turned out to be these brownish-black ladybugs!”
Eye-Spotted Ladybug (Anatis mali)
Eye-spotted ladybug, pupa, Anatis mali, family Coccinellidae.
□ Beetles go through four phases: egg, larva, pupa, adult. This is the pupa, likely from an eye-spotted ladybug. As seen in the photo at left, the pupa will often attach one end to a surface, usually a leaf or stem, but in this case man-made material. To see a great time-lapse video of a ladybug going through its four stages here.
□ The adult eye-spotted ladybug is orange with white-outlined black spots.
Photographed by: Amanda Russell. Identified by: KnowYourInsects.org. Location: Camillus, New York, USA. Date: 3 July, 2020.
Amanda says, “I’ve never seen a ladybug pupa before, but it looked really cool.”
10-Spot Ladybird Beetle (Adalia decempunctata)
10-spot ladybird beetle, Adalia decempunctata, family Coccinellidae.
□ The 10-spot ladybird beetle is quite a variable species. This specimen has 10 spots, but not all of them do. To see the considerable variation within this species, click here (on naturespot.org.uk).
Photographed and identified by: Bryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 2 January, 2018.
Bryan says, “Looks like a tortoise, but it’s only 4mm long! Two shots of it, one with wings partly unfurled.”
14-Spot Ladybird Beetle (Propylea quattuordecimpunctata)
14-spot ladybird beetle, Propylea quattuordecimpunctata, family Coccinellidae.
□ The spots on the back of a 14-spot ladybird beetle often run together, as they do on the beetle in this photo. To see the variation within this species, click here (on naturespot.org.uk).
Photographed and identified to family by: BBryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 11 May, 2019.
20-Spotted Ladybird Beetle (Psyllobora vigintimaculata)
20-spotted ladybug/ladybird beetle, Psyllobora vigintimaculata, family Coccinellidae.
□ Depending on which spots you count on this 20-spotted ladybug, you might end up with more than 20. Nonetheless, there are a lot of spots on this beetle!
Photographed and identified by: Damian Duron. Location: Watsonville, California, USA. Date: 19 October, 2017.
Damian says, “This guy is itty bitty, it’s around 5 mm (?). That was taken on my very old formica counter.” KnowYourInsects.org replies, “Nice estimation on size, Damian! This beetle is indeed tiny, growing to about 3 mm long.”
Spotless Lady Beetle (Cycloneda sanguinea)
Spotless lady beetle, Cycloneda sanguinea, family Coccinellidae.
□ Not surprisingly, the spotless lady beetle lacks spots on the elytra (hardened forewings). To tell the female from the male, look at the pattern on the pronotum. In the male, the white outline continues around the front of the pronotum and he has a white line partially down the center of the pronotum (photo here on bugguide.net). In the female, the white outline is broken and she has no central white line (photo here).
Photographed by: Marv Goldberg. Identified by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 5 April, 2019.
Marv says, “I don’t believe I ever saw a no-spotted ladybug before (I swear, I didn’t paint it).”
Ladybug larva (Harmonia eucharis)
Predaceous ladybird beetle, larva, Harmonia eucharis, family Coccinellidae.
□ The larvae of this species of predaceous ladybird beetle all have these lovely cream-colored markings on the abdomen — almost like embroidery looped stitches. The adults of this species, however, come in a wide color and pattern variation, as shown here.
Photographed by: Syed Gazanfar. Identified by: KnowYourInsects.org. Location: Kashmir, India. Date: 23 April, 2018.
Harlequin ladybird beetle (Harmonia axyridis)
Harlequin ladybird beetle, also known as an Asian multicolored ladybug, Harmonia axyridis, family Coccinellidae.
Harlequin ladybird beetles come in a wide range of color patterns, but this is one of the most common. This species is native to eastern Asia, and was purposely introduced to Europe as well as North America to control pests, such as aphids. It is now common in its new environs.
Photographed and identified by: Leslie Mertz. Location: Houghton Lake, Roscommon County, Michigan, USA. Date: 7 July, 2017.

Photographed by: Dick Ford. Identified by: KnowYourInsects.org. Location: Marsolan, Midi-Pyrénées, southwest France. Date: 28 May, 2017.
Dick says, “I live in southwest France, where we have been devastated by the box tree moth caterpillar (Cydalima perspectalis) which is gobbling up box hedges throughout the countryside. Searching for the beastly thing in my box hedge I came across this chap.”
Ladybug larva (Harmonia axyridis)
Ladybug, larva, likely the Harlequin ladybird beetle, also known as an Asian multicolored ladybug, Harmonia axyridis, family Coccinellidae.
□ This larva was about the size of a large grain of rice. It is likely a harlequin ladybird beetle.
Photographed by: Rhonda Baxter. Identified by: KnowYourInsects.org. Location: Dearborn, Michigan, USA. Date: 8 June, 2016.
Rhonda says, “The larva survived and grew! I put it out on my rosebush. I was wondering if it made it through to an adult today, and as I was eating my dinner, this ladybug landed on my window screen across from me. It is the only one I have seen around my house at all this year. I am hoping it was the one I saved. I guess I am a crazy bug lady. LOL.”

Lampyridae, the fireflies or lightningbugs

Winter Firefly (Ellychnia corrusca)
Winter firefly, also known as diurnal or day-flying firefly, Ellychnia corrusca, subfamily Lampyrinae, family Lampyridae.
□ The winter firefly is distinguished from the black firefly (Lucidota atra), which occupies a somewhat similar range, by being larger, lighter in coloration, and having thinner antennae. The black firefly is shown elsewhere on this page.
Photographed by: Leslie Mertz. Identified by: Jackie Lucier. Location: Kalkaska County, Michigan, USA. Date: 28 May, 2012.
Winter Firefly (Ellychnia corrusca)
Winter firefly, also known as diurnal or day-flying firefly, Ellychnia corrusca, subfamily Lampyrinae, family Lampyridae.
Winter fireflies are not only diurnal, but as adults age they no longer light up (bioluminesce). Larvae and pupae both bioluminesce, as do newly metamorphosed adult fireflies.
Photographed and identified by: Leslie Mertz. Location: Gaylord, Otsego County, Michigan, USA. Date: 27 May, 2017.
Black Firefly (Lucidota atra)
Black firefly, Lucidota atra, subfamily Lampyrinae, family Lampyridae.
□ This black firefly has a colorful yellow, red and black pronotum (the shield covering its thorax). When it flies, its black elytra (the hard forewings) spread to the sides, revealing its membranous flight wings. The flight wings unfold to take it into the air. The adult female of this species flashes, but the adult male only flashes for a short time immediately after he transforms from a pupa to and adult.
Photographed by: Debby Wright. Identified by: KnowYourInsects.org. Location: Waterford, Michigan, USA. Date: 9 June, 2020. Debby says, “Oh my goodness. I love fireflies.”
Big Dipper Firefly (Photinus pyralis)
Big dipper firefly, Photinus pyralis, subfamily Lampyrinae, family Lampyridae.
Big dipper fireflies have black elytra (the forewings that cover most of their backs) with cream-colored outlines around each. The thorax has a large pink blotch with a black center. See the underside of this insect in the next photo.

Firefly larva (family Lampyridae) or net-winged beetle larva (Lycidae)
Either a larva of a firefly, family Lampyridae (the fireflies or lightningbugs) OR of a net-winged beetle, family Lycidae.
□ Even though fireflies and net-winged beetles are in two separate families, their larvae are essentially indistinguishable. Either way, this a a cool larva ... and check out that retractable head!
Photographed by: Eric Smith. Identified by: KnowYourInsects.org. Location: Hoover, Alabama, USA. Date: 8 February, 2017.
Firefly larva (family Lampyridae) or net-winged beetle larva (Lycidae)
Either a larva of a firefly, family Lampyridae (the fireflies or lightningbugs) OR of a net-winged beetle, family Lycidae.
□ With the plates on the back, the weird retractable head, and the long body, it is hard to believe that this could be a larva (immature) of a firefly or a net-winged beetle!
Photographed by: Maiya Patrick. Identified by: KnowYourInsects.org. Location: Southwest Michigan, USA. Date: 26 April, 2018.
Maiya says, “I did get to see the head pop out! It was really cool.”
Firefly larva (family Lampyridae) or net-winged beetle larva (Lycidae)
Either a larva of a firefly, family Lampyridae (the fireflies or lightningbugs) OR of a net-winged beetle, family Lycidae.
Photographed by: Cheryl Hennessy. Identified by: KnowYourInsects.org. Location: Prince’s Grant estate in KwaZulu-Natal, South Africa. Date: 13 January, 2018.
Cheryl says, “Could be a firefly larva as we have observed one in a similar location. I have never seen this little one before, which is why I am so curious. It also uses its abdomen in locomotion, and the end of its abdomen has small appendages which it can use to grip.”
Lampyrid larva (Nyctophila caucasica)
Larva of a firefly, possibly Nyctophila caucasica, subfamily Lampyrinae, family Lampyridae.
□ This larva is shown curled up. Such a posture helps to protect the softer underside of the insect from predators.
