Western Leaf-Footed Bug
Western Leaf-Footed Bug, Leptoglossus clypealis, family Coreidae (the leaf-footed bugs), suborder Heteroptera.
□ The scientific species name of clypealis refers to the small needle-like structure on the front of the head, which is visible in this photo — that is, if you look closely! That structure is actually an extension of a plate, called a clypeus, on the insect’s “face”.
Photographed by: Pam Meintzer. Identified by: KnowYourInsects.org. Location: Johnstown, Colorado, USA. Date: 12 October, 2016.
Pam says, “Ahhhhhhhhh!!!! It is huge and creepy looking. I don’t know what it is; hope you know!”
Western Leaf-Footed Bug
Western Leaf-Footed Bug, Leptoglossus clypealis, family Coreidae (the leaf-footed bugs), suborder Heteroptera.
□ Note the wide flair on the hind legs. It almost looks like a leaf, and that is the origin of the name “leaf-footed”.
Photographed and identified by: Chris McClelland. Location: Albuquerque, New Mexico, USA. Date: 13 October, 2017.
Chris photographed this bug on a bench in her backyard.
Leaf-footed Pine Seed Bug (Leptoglossus corculus)
Leaf-Footed Pine Seed Bug, Leptoglossus corculus, family Coreidae (the leaf-footed bugs), suborder Heteroptera.
□ This species has three small white dots, as well as an often-faint and blurred white zigzag on its back. The three white dots are visible in this photo, but not the zigzag pattern. Another feature of this species is the series of light-colored lines that run along each side of its abdomen. If you zoom in, you can see them (especially along the lower part of the abdomen in this photo).
Photographed by: Anonymous. Identified by: KnowYourInsects.org. Location: Dutchess County, New York, USA. Date: 15 September, 2017.
Western Conifer Seed Bug
Western Conifer Seed Bug, Leptoglossus occidentalis, family Coreidae (the leaf-footed bugs), suborder Heteroptera.
□ A good (but technical) description of the different but similar-looking species in this genus is available in a 1990 article that appeared in the Great Lakes Entomologist journal. To see the article, “Eastern Range Extension of Leptoglossus occidentalis With a Key to Leptoglossus Species of America North of Mexico (Heteroptera: Coreidae)”, click here.
Photographed and identified to genus by: Tia and Scott Levinson. Location: Putnam Valley, Putnam County, New York, USA. Date: 6 February, 2018.
Tia says, “This guy joined us for dinner.”
Western Conifer Seed Bug
Western Conifer Seed Bug, Leptoglossus occidentalis, family Coreidae (the leaf-footed bugs), suborder Heteroptera.
□ This insect is actually native to the western United States, which is why it is called the Western Conifer Seed Bug. It started to march east around the middle of the 20th century, and is now found in the northeastern United States too.
Photographed and identified by: Karen Dillon. Location: Berlin, Vermont, USA. Date: 10 March, 2017.
Karen says, “Climbing on my indoor window in the first week of March! Maybe escaped from some potting soil. I love the little ‘alien face’ on his upper back.”
Western Conifer Seed Bug
Western Conifer Seed Bug, Leptoglossus occidentalis, family Coreidae (the leaf-footed bugs), suborder Heteroptera.
□ When cooler weather sets in, these insects will sometimes seek shelter indoors. They don’t bite, but if they feel threatened (e.g., if you try to pick one up), they may emit a pungent odor. That’s their defense mechanism!
Photographed by: Cindy Karch. Identified by: KnowYourInsects.org. Location: Macungie, Pennsylvania, USA. Date: 8 August, 2017.
Cindy says, “So cool! ... It’s really beautiful.”
Leaf-footed bug

 Wheel bug
Wheel Bug, Arilus cristatus, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This is a newly metamorphosed Wheel Bug, so it has just molted from a nymph (immature or juvenile) into an adult. The pink color will soon darken to browns and grays.
Photographed by: Jessica Claypool. Identified by: KnowYourInsects.org. Location: Unknown. Date: 19 September, 2016.
Wheel bug larva
Wheel Bug, nymph (immature), Arilus cristatus, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This is a great photo of the nymph of the Wheel Bug. Compare it to the photos of adults posted just before this one.
Photographed by: Jeremiah and Caitriona Kane. Identified by: KnowYourInsects.org. Location: East Bradford, Pennsylvania. Date: 16 July, 2017.
“My wife, daughter and I were having a lot of fun trying to figure out what it was, so you responding so quickly made our night.” KnowYourInsects.org says, “This photo was a family affair: Louise found it, and her husband Jere and daughter Caitriona snapped the photo! Nice group effort, Kane family!”

Santhosh says, “I found it on my neck.”
Sundew Assassin Bug
Sundew Assassin Bug, also known as a Pale Green Assassin Bug Zelus luridus, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This species secretes a sticky substance, called sundew, that helps their front legs grab onto prey. (Most other assassin bugs don’t secrete a sticky substance.)
Photographed by: Marian Williams. Identified by: KnowYourInsects.org. Location: near Waco, Carroll County, Georgia, USA. Date: 27 August, 2017.
Marian says, “I’m sure I’ve seen similar bugs before but never looked so close. I found him/her to be very interesting.”
Sundew Assassin Bug
Sundew Assassin Bug, also known as a Pale Green Assassin Bug, Zelus luridus, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
Photographed by: Marian Williams. Identified by: KnowYourInsects.org.
□ A key characteristic of the Sundew Assassin Bug is the pair of thorn-like projections on the thorax, as shown here. Note: Although they are sometimes called Pale Green Assassin Bugs, this species is not always pale green.
Location: near Waco, Carroll County, Georgia, USA. Date: 27 August, 2017.
Sundew Assassin Bug
Sundew Assassin Bug, also known as a Pale Green Assassin Bug, nymph (immature), Zelus luridus, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This is a nymph, or an immature Sundew Assassin Bug. And it is exhibiting its predatory behavior — this is why they are called Assassin Bugs! (See Erik’s comment below.)
Photographed by: Arthur Ferruzzi. Submitted by: Erik Paschke. Identified by KnowYourInsects.org. Location: Michigan. Date: 26 April, 2018.
Erik says, “This bug was sucking the head of an ant.”
Sundew Assassin Bug/Pale Green Assassin Bug
Sundew Assassin Bug, also known as a Pale Green Assassin Bug, nymph (immature), Zelus luridus, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ The photographer reports this insect as about 3/8 inch (about 0.9 cm) in body length, and less than 3/4 inch (1.9 cm) in total length, including antenna.
Photographed by: Don Leith. Identified by KnowYourInsects.org. Location: Lyon Township, Michigan. Date: 10 November, 2018.
Don says, “My boys are regularly spotting new creatures and we enjoy the online hunt of identifying and understanding their place in our ecosystem.” KnowYourInsects.org applauds this family effort!
Spiny Assassin Bug (Sinea)
Spiny Assassin Bug, nymph (immature), genus Sinea, subfamily Harpactorinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ Now that is one prickly insect! Adult Spiny Assassin Bugs still have spines, but they are much less pronounced than they are on the nymphs (like this one).
Photographed by: Heather Bond. Identified by: KnowYourInsects.org. Location: Tucker, Georgia, USA. Date: 30 June, 2017.
Heather says, “It was found in my kitchen on the counter.”
Spiny Assassin Bug (Sinea)

Jagged Ambush Bug
Jagged Ambush Bug in the genus Phymata, nymph, subfamily Phymatinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ When an unwary prey insect comes near, the Jagged Ambush Bug lashes out with its large and strong forelegs. Its forelegs not only grab the prey, but also hold onto it as the Jagged Ambush Bug stabs the prey with its long beak. Check out the photographer’s comment about the tiny size (below).
Photographed and identified to family by: Gail Rowley, Ozark Stream Photography. Identified to genus by: KnowYourInsects.org. Location: Texas County, Missouri, USA. Date: 14 April, 2018.
Gail describes this as looking like “a speck of dust on my husband’s shirt after he was pulling invasive Spotted Knapweed in our field. The speck of ‘fluff’ moved, so I put it in a jar with a piece of house plant and captured a shot with all my extension tubes on my macro lens.”
Jagged Ambush Bug
Jagged Ambush Bug in the genus Phymata, subfamily Phymatinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This photograph of an adult Jagged Ambush Bug gives a good view of its large forelegs. Unlike the nymph shown previously, this one has a wider thorax, so it is an older individual. The photographer gives a description below.
Photographed and identified to family by: Gail Rowley, Ozark Stream Photography. Identified to genus by: KnowYourInsects.org. Location: Texas County, Missouri, USA. Date: 14 April, 2018.
Gail says this was on a butterfly weed plant (Asclepias tuberosa) in her field. She says, “I was aiming for a flower’s insides with all my tubes and macro lens when this tiny guy became visible. My naked eye didn’t see it. It seems to be holding onto something in its ‘claws.’”
Jagged Ambush Bug
Jagged Ambush Bug, Phymata pennsylvanica, subfamily Phymatinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ The Jagged Ambush Bug earns the name “ambush,” because it sits still in flowers and waits for an unwary insect to happen by. When an insect comes close, the Jagged Ambush Bug lashes out with its large and strong forelegs, and grabs the prey. Prey may include all sorts of insects, including flies and bees that may be much larger than the ambush bug. Although the adult has wings (as shown), it is not a good flier (and rarely flies).
Photographed by: Dave Brigham. Identified by: KnowYourInsects.org. Location: Lansing, Michigan, USA. Date: sometime in the 1970s.
Dave says he took this photo “with a 100 mm bellows, so it’s pretty small — guessing about 4mm.”
Ambush Bug, genus Phymata
Ambush Bug, nymph, probably in the genus Phymata, subfamily Phymatinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This Ambush Bug nymph (immature) is showing off its piercing mouthparts, called the rostrum. Notice the large forelegs, which are characteristic among species within this genus.
Photographed by: Jessica Milko. Identified to family by: entomologist J. E. McPherson. (Thank you, Dr. McPherson!) Identified to genus by: KnowYourInsects.org. Location: Washington Township, Michigan, USA. Date: 28 July, 2018.
Western Corsair Bug
Western Corsair Bug, Rasahus thoracicus, subfamily Peiratinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ This Western Corsair Bug looks quite similar to the Corsair Assassin Bug shown elsewhere on this page, especially with the large spot on the rear of their wings. The Western Corsair Bug, however, also has orange flanking on the forward half of its wings, and the Corsair Assassin Bug does not.
Photographed by: LC. Identified by: KnowYourInsects.org. Location: north of San Francisco, California, USA. Date: 28 August, 2016.
Western Corsair Bug
Western Corsair Bug, Rasahus thoracicus, subfamily Peiratinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ Western Corsair Bugs usually go about their business of killing and eating other insects, and have no interaction with humans. If a person picks one up or otherwise harrasses it, however, the Western Corsair Bug can give a painful poke with their spear-like beak.
Photographed by: Anthony Romero. Identified by: KnowYourInsects.org. Location: Ventura, California, USA. Date: 12 July, 2018.
Anthony says, “Well, I think this is very cool. We had not seen such an interesting species before and I really had a difficult time tracking information down online not knowing the name, but you came through like a champ. Thank you for the insights and help.” KnowYourInsects.org says, “You’re welcome, Anthony!”
Corsair Assassin Bug
Corsair Assassin Bug, Rasahus hamatus, subfamily Peiratinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
Photographed by: Heather Hazlett. Identified to order by KnowYourInsects.org. Location: central Texas, USA. Date: 2 June, 2017.
Reduviid
Blood-Sucking Conenose, a species in the Triatoma genus, subfamily Triatominae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ See the note below about this insect, which is associated with serious disease. It is sometimes erroneously called a “masked hunter,” but the real Masked Hunter is a separate species and not even in the same genus as the Conenose. To read more about the Conenose, click here.
Photographed and identified to order by: Robert Lewis. Identified to genus by Thi Nhi Pham, Institute of Ecology and Biological Resources, Vietnam Academy of Science and Technology. Location: Ho Chi Minh City, Vietnam. Date: 17 March, 2017.
Thi Nhi Pham notes that all members of the subfamily Triatominae “are blood-sucking insects that can transmit serious diseases.”
Masked Hunter (Reduvius personatus)
Assassin Bug, possibly a Masked Hunter, Reduvius personatus, subfamily Reduviinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ The Masked Hunter is sometimes called the Masked Bed Bug Hunter because it attacks and eats bed bugs, among assorted other invertebrates. It is a nocturnal hunter, and usually stays out of sight during the day. Note: The Blood-Sucking Conenose (shown elsewhere on this page) is sometimes erroneously called a “masked hunter,” because it looks similar, but it is a separate species and not even in the same genus as the Masked Hunter. To read more about the Conenose, which can transmit serious disease, click here.
Photographed by: Anonymous. Identified by: KnowYourInsects.org. Location: Toronto, Canada. Date: 9 July, 2018.
Masked Hunter (Reduvius personatus)
Masked Hunter, nymph (immature), Reduvius personatus, subfamily Reduviinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ According to Dr. Duke Elsner, “The nymphs are coated with sticky hairs, and they get covered with whatever small particulate material they come in contact with. The adults are shining deep-brown to black, and do not have the sticky hairs.” To see the adults, click here.
Photographed by: Denise Rulason. Identified by: entomologist Duke Elsner. Thank you, Dr. Elsner! Location: Mayville, Michigan, USA. Date: 18 September, 2017.
Denise says, “It was “VERY small. Possibly (the size of the) eraser on a pencil for circumference with legs.”
Thread-Legged Bugs
A mating pair of Assassin Bugs, likely Thread-Legged Bugs in the genus Emesaya, subfamily Emesinae, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ It is difficult to see, but this is a mating pair of assassin bugs, connected hind end to hind end. Both the male and female are very skinny insects, four legs of each one is pointing forward and the hind pair extending out to the rear.
Photographed by: Meem Sarkar. Identified by: KnowYourInsects.org (with a nudge in the right direction from entomologist Thies Büscher). Location: Bengaluru, Karnataka, India. Date: 15 October 2015.
Reduviid
Assassin Bug, family Reduviidae (the assassin bugs), suborder Heteroptera.
□ Notice the beak that extends backward from the head. Assassin bugs use the beak to stab prey insects and suck out their body fluids.
Photographed by: Mark Smith. Identified to order by KnowYourInsects.org. Location: Huntington Woods, Michigan, USA. Date: 2 July, 2013.

Pentatomidae (the stink bugs)

White Stink Bug nymph (Degonetus serratus)
White Stink Bug, nymph (immature), Degonetus serratus, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ This stunning White Stink Bug nymph looks much more subdued as an adult — as an adult, it is ochre-colored. It feeds on teak (Tectona grandis, a tropical tree that produces much-appreciated hard wood, and the photographer found this nymph on a teak tree.
Photographed and identified to order by: Surabhika Panda. Identified to species by: KnowYourInsects.org. Location: Navsari, Gujarat, India. Date: 10 December, 2018.

Southern Green Stink Bug (<i>Nezara viridula</i>)
Southern Stink Bug, nymph (immature), Nezara viridula, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ Insects go through stages as they grow, and the stages are called instars. This appears to be a fourth instar nymph of the Southern Green Stink Bug, so it only needs to molt twice more before becoming an adult. The adult is a shamrock green.
Photographed and identified by: Damian Duron. Location: Watsonville, California, USA. Date: 19 October, 2017.
Damian says, “I am afraid these guys are not too good for my garden. (They) infested my green beans this year.” KnowYourInsects.org replies, “We are gardeners, soo, so we share your pain!”

Southern Green Stink Bug (Nezara viridula)
Southern Green Stink Bug, Nezara viridula, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ This series of photographs provides the view from the top, bottom and head-on. The bottom view shows the scent glands, which are the two gray shapes at the center of thorax and right behind the front legs. These glands are what produces the foul-smelling substance these insects are known for. In other words, they put the “stink” in stink bugs! The head-on view shows the two big compound eyes, plus two much smaller eyes (called ocelli) that look like orange-and-black droplets. The compound eyes help insects to see full images, while the ocelli are light-sensing receptors that pick up motion only — great for spotting and eluding approaching predators.

Angela says, “Found this beetle on a window in our house. In December!” KnowYourInsects.org says, “While it is often assumed to be a beetle, it is actually a stink bug, which is in an entirely different insect order. Such a cool bug!”
Stink bug nymph
Stink Bug, nymph (immature), possibly a Two-Spotted Stink Bug, Perillus bioculatus, family Pentatomatidae (the stink bugs), suborder Heteroptera.
□ This is a nymph of one of the stink bugs, but even after checking with four stink bug experts, we cannot be sure of the species. Because it was found on potato plants, however, one of the experts said it was likely a Two-Spotted Stink Bug, which prey on Potato Beetles.
Photographed by: Jenny Hotz. Identification assistance provided by: entomologist Robert Koch of the University of Minnesota, and Tom Coudron of the U.S. Department of Agriculture’s Agricultural Research Service, who also consulted two other stink bug experts. Thank you all for your help! Location: Unknown. Date: 26 July, 2017.

Man-faced stink bug
Man-Faced Stink Bug, also known as Man-Faced Shield Bug, Catacanthus incarnatus, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ This is the red version, or morph, of the Man-Faced Stink Bug. Other color morphs are orange, yellow, and a yellowish-white. They all have the same black markings. As with many other red insects, it is believed that the color advertises to predators that it is noxious, so they should look elsewhere for a meal.

Green shield bug
Green Shield Bugs, mating pair, Palomena prasina, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ Depending on the lighting that triangular section of tan wings may appear dark brown. That section is actually where the back half of the forewings overlap. The back half is membranous, while the front half is much thicker and green.
Photographed and identified by: Bryan Wenham-Baker (@BryanPhotos). Location: Near Ivybridge, South Hams, South Devon, England, UK. Date: 3 May, 2018.
Bryan says, “Sun came out this morning, nice walk, but when I returned home, found these two Green Shield Bugs mating. Can’t turn one's back for a minute!!”
Rough Stink Bug (genus Brochymena)
Rough Stink Bug (sometimes called the Predatory Stink Bug), in the genus Brochymena, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ The number of Rough Stink Bugs has been declining in North America ever since the non-native and invasive stink bug called the Brown Marmorated Stink Bug (shown elsewhere on this page) arrived and began taking over territory where the Rough Stink Bug is found.
Photographed by: Karen Skowron. Identified by: KnowYourInsects.org. Location: Victoria, British Columbia, Canada. Date: 28 January, 2018.
Karen describes, “Having found this insect on floor of my suite and watched its unusual behaviour of twirling around and how it calmed down when I put down a piece of paper and took its photo.”
Rough Stink Bug (genus Brochymena)
Rough Stink Bug (sometimes called the Predatory Stink Bug), in the genus Brochymena, family Pentatomidae (the stink bugs), suborder Heteroptera.
□ The photographer asked if this was the invasive stink bug (the Brown Marmorated Stink Bug that has spread throughout much of the United States). A close look at this photo, however, shows a row of little teeth on the leading edge of the thorax (in the “shoulder” area right next to the eyes. Brown Marmorated Stink Bugs do not have these teeth, but Rough Stink Bugs do. So this is a Rough Stink Bug, which is native to the United States.
Photographed by: Tara Castleberry. Identified by: KnowYourInsects.org. Location: Boise, Idaho, USA. Date: 29 September, 2018.
Tara says it came to her mountain home with the cooler weather. She is “thrilled it isn’t the invasive stinker :). ”

Gerridae (the water striders)

Water strider
Water Strider, family Gerridae (the water striders), suborder Heteroptera.
□ Water Striders skate along the surface of the water, which is why they are sometimes called pond skaters. They can also tap down with their legs on the water surface to make ripples, and scientists believe they use these ripples to communicate with one another. Note: This insect holds its foremost pair of legs out front, so they look almost like antennae.
Photographed and identified by: Bryan Wenham-Baker (@BryanPhotos). Location: Near Ivybridge, South Hams, South Devon, England, UK. Date: 4 September, 2017.
Bryan provided the list of common names this insect goes by: “Water Skater; Pond Skater; Water Skipper; Skimmer; Water Strider; and Jesus bug.” He adds that it took him a minute to get the Jesus bug reference — after all, this insect does walk on water!

□ The Grouse-Winged Backswimmer and other backswimmer species actually swim upside down, often lying on their backs at the surface of the water and propelling themselves with a kick of their long hind legs (held out sideways in the photo here). They are often seen flying up (or leaping up) out of the water, which traps some air under their wings. The insect then uses that trapped air to breathe. The Grouse-Winged Backswimmer is a species of the western United States, but this individual was discovered in New York, so an unusual find!
Photographed by: Daniel Lewis. Identified by: KnowYourInsects.org. Location: Bethpage, Long Island, New York, USA. Date: 2 July, 2018.
Daniel says he found this one in his pool.

Backswimmer, Notonecta irrorata
Backswimmer, Notonecta irrorata, family Notonectidae (the backswimmers), suborder Heteroptera.
□ This species of Backswimmer gives off a chemical that repels mosquitos, so sharing a swimming pool with one can keep mosquitos from laying eggs there. On the other hand, backswimmers do bite and it can be painful, so it’s best not to come into direct contact with one. See the photographer’s comment below about backswimmers in a pool.
Photographed and identified to order by: Steven M. Nassor. Identified to species by: KnowYourInsects.org. Location: Massachusetts, USA. Date: 16 October, 2018.
Steven says he found several of these backswimmers when he was closing the swimming pool for the year. He says, “Just noticed them after the weather changed. We didn’t close the pool right away and left it with no maintenance. A few weeks later when topping the pool off, we were vacumming some leaves and began to notice several of them.”

Lygaeidae (the milkweed bugs and seed bugs)

Milkweed bugs (<i>Oncopeltus fasciatus</i>)
Milkweed Bugs, nymphs (immatures), Oncopeltus fasciatus, family Lycaeidae, (the milkweed bugs and seed bugs), suborder Heteroptera.
□ These are immature milkweed bugs, or milkweed bug nymphs. The bright orange-red color helps potential predators to know that they taste bad, and therefore helps to protect them from being eaten.
Photographed by: Susan Barron. Identified by: KnowYourInsects.org. Location: Frenchtown, New Jersey, USA. Date: 18 September 2016.
Susan found these nymphs on butterfly weed, which is a kind of milkweed plant with beautiful orange flowers.
Seed Bug the genus <i>Nysius</i>
Seed Bug possibly in the genus Nysius, family Lygaeidae (the milkweed bugs and seed bugs).
□ The large eyes, the antennae, and the swollen nature of the forelegs led Dr. H.M. Yeshwanth, an entomologist at the University of Agricultural Sciences in Bangalore, India, to tentatively identify this as a member of the genus Nysius. Without a clearer photo, however, he cannot rule out a different genus in this family, or possibly a species in the Geocoridae family (known as the big-eyed bugs) or maybe even the Coreidae family (the leaf-footed bugs).
Photographed by: Siddanth Sanil. Identified by: entomologist Dr. H.M. Yeshwanth of the University of Agricultural Sciences in Bangalore, India. Thank you, Dr. Yeshwanth! Location: Bangalore, India. Date: 9 December, 2017.
Siddanth says, “I found this insect in my hostel room in Bangalore, India. It’s grey in colour and is tiny and calm.”

Soldier Bug (Spilostethus pandurus)
Soldier Bug, adult and nymph (immature), Spilostethus pandurus, family Lygaeidae (the milkweed bugs and seed bugs), subfamily Lygaeinae.
□ The photographer was diligent, because he not only photographed the nymph (right), but later went back to find the adult. The nymph of the Solider Bug has two noticeably white-ringed black spots on its abdomen. The adult is distinguished by the pattern on its thorax, as well as the white spots on the black section of its wings.
Photographed by: Hussain Alsalem. Identified by: entomologist Bertrand Horne, research fellow, Kutch Ecological Research Centre, a unit of The Corbett Foundation, Kutch, Gujarat, India. Thank you, Dr. Horne! Location: Najran City, Saudi Arabia. Date: 30, April 2018 (for the nymph), and 18 May, 2018 (for the adult).
Hussain says neither he (nor his mother) had ever seen these insects before, but found hundreds of the nymphs near home.

Monica says, “I am not sure if they fly or just jump, (but) when I am in the garage or close to where they are, I always get a few on myself.”
Red-shouldered bug
Red-Shouldered Bug, also known as a Jadera Bug, nymph (immature), Jadera haematoloma, family Rhopalidae, (the scentless plant bugs), suborder Heteroptera.
□ The nymphs of red and black milkweed bugs look similar, but have rows of black dots down the abdomen. When the nymph of the Red-Shouldered Bug becomes an adult, black wings will cover the abdomen.
Photographed by: Shelley. Identified by: KnowYourInsects.org. Location: Los Angeles, California. Date: 8 November, 2016.
Shelley says, “And they are in massive numbers — hundreds of them. All different stages!”

Box elder bug
Box Elder Bug, Boisea trivittata, family Rhopalidae, (the scentless plant bugs), suborder Heteroptera.
□ Check out that handsome red and black pattern! The box elder bug is not tasty to predators, and the red color helps to let predators know that they should find a meal elsewhere. A side note: When the weather turns cold, groups of box elder bugs will congregate someplace warm, occasionally in houses.

Box elder bug
Box Elder Bug, nymph (immature), Boisea trivittata, family Rhopalidae, (the scentless plant bugs), suborder Heteroptera.
□ Immature Box Elder Bugs, like this nymph, are often found in large groups. Nymphs go through five stages, or instars, becoming darker and darker red with each passing instar. The black wing buds (too undeveloped for flight) become longer at each stage. This nymph is probably a fifth instar, and with the next molt, it will become an adult (as shown in the previous photo).

Rhyparochromidae (the dirt-colored seed bugs)

Long-Necked Seed Bug (<i>Myodocha serripes</i>)
Long-Necked Seed Bug, Myodocha serripes, family Rhyparochromidae, (the dirt-colored seed bugs), suborder Heteroptera.
□ The long neck is very distinctive for this genus. Another characteristic of the Long-Necked Seed Bug is the enlarged femur (its “thigh”). One of its favorite seeds are those of strawberries, so they can occasionally be a pest of these fruits. This insect only grows to about 1 cm (3/8 inch) long.

Tarnished Plant Bug (Lygus lineolaris)
Tarnished Plant Bug, Lygus lineolaris, fifth instar nymph, family Miridae (the plant bugs, leaf bugs, and grass bugs), suborder Heteroptera.
□ As the nymphs of the Tarnished Plant Bug grow older — from first instar nymphs to fifth instar nymphs (the last stage before becoming an adult) — they gain more spots and also develop wing buds. This fifth instar nymph has four spots on its thorax, one more in the center of its abdomen, and wing buds. For more information about this species, click here.

Coccidae

Calico scale insect
Calico Scale Insect, Eulecanium cerasorum, family Coccidae, Suborder Sternorrhyncha.
□ Calico Scale Insects are usually seen on the sides of certain trees, including maples, elms, dogwoods, and a variety of stone fruits (e.g., plums, cherries, peaches, and nectarines). They produce a sticky substance, called honeydew, which is a breeding ground for a black fungus. For more information about these insects, click here.

□ Calico Scale Insects were introduced into San Francisco, California, about a century ago, and have spread through the western United States. More recently, they’ve also moved into a few eastern states, with the first reports in Michigan (where this photo was taken) coming from the far southern part of the state in around 2007.

Barnacle scale insect
Barnacle Scale Insects, Ceroplastes cirripediformis, family Coccidae, Suborder Sternorrhyncha.
□ Barnacle Scale Insects live in aggregations on stems, as shown in the bottom photo. They often become infested with parasitoid wasps — the wasps lay eggs in the soft bodies of the Barnacle Scale Insects, the eggs hatch inside and when they mature, tiny wasps fly out of the scale insects.
Photographed by: K J Westman. Identified by: KnowYourInsects.org. Location: Sri Landa. Date: 25 August, 2018.
K J says, “They are very symmetric and will in some places totally cover the stem they are living on.”
