Silphidae, the carrion beetles

Burying Beetle (<i>Nicrophorus sayi</i>)
Burying Beetle (also called a carrion beetle), Nicrophorus sayi, family Silphidae (the carrion beetles).
□ These 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.
Burying Beetle (<i>Nicrophorus sayi</i>)
Burying Beetle (also called a carrion beetle), Nicrophorus sayi, family Silphidae (the carrion beetles).
□ Look for the tiny red mites on this beetle. They 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 8 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 (<i>Nicrophorus investigator</i>)
Red and Black Banded Sexton Burying Beetle (also called a Sexton Beetle), Nicrophorus investigator, family Silphidae (the carrion beetles).
□ These 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.

Dermestidae, the dermestid or skin beetles

Larder beetle (Dermestes lardarius)
Larder Beetle, Dermestes lardarius, family Dermestidae (the dermestid or skin beetles).

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, family Dermestidae (the dermestid or skin beetles).
□ One way to distinguish the larva of a Varied Carpet Beetle from the similar Furniture Carpet Beetle (Anthrenus flavipes or Black Carpet 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, family Dermestidae (the dermestid or skin beetles).
□ 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.
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.”

Phengodidae, the glowworm beetles

Glowworm beetle
Glowworm Beetle, male, Phengodes plumosa, family Phengodidae (the glowworm beetles).
□ The males are impressive with those plume-like antennae. The females, on the other hand, look like grubs and they are bioluminescent ... so they glow!
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’!”

Bumble Flower Beetle (<i>Euphoria inda</i>)
Bumble Flower Beetles, Euphoria inda, family Scarabaeidae (the scarab beetles).
□ A row of these cute 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.
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.”
Grapevine Beetle (<i>Pelidnota punctata</i>)
Grapevine Beetle, Pelidnota punctata, family Scarabaeidae (the scarab beetles).
□ 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.

Green Fruit Beetle (Cotinis mutabilis)
Green Fruit Beetle (aka Figeater), Cotinis mutabilis, family Scarabaeidae (the scarab beetles).
□ The metallic green of this attractive beetle is set off by the gold stripe down the sides. 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 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)!
Rose chafers, <i>Macrodactylus subspinosus</i>
Rose Chafers, Macrodactylus subspinosus, family Scarabaeidae (the scarab beetles).
□ 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!”
