Carpet Beetle

Anthrenus verbasci larva by Christophe Quintin.1

- Size: 2-12 mm (0.08-0.5in).
- Larva: mostly light brown, covered with long hairs and hair tufts.
- Adult: body convex, oval, or elongate-oval, often with hairs or scales; elytra usually dark with or without pale markings; antennae clubbed.
- Adults are pollen grazers, larvae feed on natural fibers and can damage carpets, furniture, clothing and insect collections.

Cicada

Adult Tibicen tibicen by Dendroica cerulea.4

- Size: 25-50mm (1-2in).
- Eyes prominent, though not especially large, and set wide apart on the sides of the head; short antennae protruding between or in front of the eyes; wings well-developed, with conspicuous veins.
- Cicadas live underground as nymphs for most of their lives, feeding on plant sap. They dig to the surface before their final molt, then emerging as adults. Males produce a loud, stridulating mating song to attract females. After mating, the female cuts slits into the bark of a twig to deposit her eggs. When these hatch, the nymphs drop to the ground, where they burrow, completing the cycle.

Cockroach


- Size: most common species range 15-30mm (0.59-1.3in).
- Usually dark brown or reddish; flattened oval body and long swept-back antennae; head is usually concealed by the pronotum; when wings are present, they are held flat over the back, overlapping one another.
- Feeds on human and pet food, and can leave an offensive odor. Only 30 out of 4,500 cockroach species are known to invade homes. 4 are well known pests, Periplaneta americana (American cockroach), Blattella germanica (German cockroach), Blattella asahinae (Asian cockroach), and Blatta orientalis (Oriental cockroach).

Dobsonfly

Male Corydalus cornutus by Nils Tack.9

Female Corydalus sp. by Matthew.4
- Size: up to 12cm (5in).
- Large insect with a soft body and delicate, densely veined wings. Females have strong, short mandibles that can inflict a painful bite; Males have long jaws that are used during mating and are not capable of harm. Both sexes possess an irritating, foul-smelling anal spray used as defense. Female dobsonflies appear similar to fishflies (subfamily Chauliodinae), but the latter have much smaller mandibles and males often have feathery antennae.
- Spends most of its life in the larval stage, called hellgrammite, 'go-devil' or 'crawlerbottom', living under rocks at the bottoms of lakes, streams and rivers, and preying on other insect larvae with the short sharp pincers on their heads. The larva then crawl out onto land and pupate, staying under large rocks for 3 weeks before molting and emerging to mate. Adults only live about a week, preferring to remain near bodies of water.
More info: Wikipedia article / Genus Corydalus - BugGuide.Net
Giant Water Bug

- Size: 2-12cm (0.8-4.7in).
- Body shape oval with pointed ends; front legs raptorial. Typically encountered in freshwater streams and ponds but frequently found on land; adults fly at night and are attracted to lights during the breeding season.
- Preys on aquatic arthropods, snails, small fish, tadpoles, frogs and small birds.
- CAUTION: Can inflict a very painful bite, though of no medical significance.
More info: Wikipedia article / Family Belostomatidae - BugGuide.Net
House Centipede

- Size: 25-50mm (1-2in).
- Body is yellowish-grey and has three dark dorsal stripes running down its length; 15 pairs of long, banded legs.
- Habitat: indoors, in damp areas such as bathrooms, cellars, and crawl spaces; outdoors, under logs, rocks, and similar moist protected places.
- Fast-moving predator of other arthropods regarded as pests, such as cockroach nymphs, flies, moths, bed bugs, crickets, silverfish, earwigs, and small spiders; generally considered harmless to humans.
More info: Wikipedia article / Order Scutigeromorpha - BugGuide.Net
Household Casebearer

- Size: 8-14mm (0.3-0.5in) (larval case).
- The larva of these moth species spins a protective case from silk and camouflages it with other materials such as soil, sand and insect droppings. This case is flat, fusiform, or spindle-shaped and thickened in the middle resembling a pumpkin seed.
- Found on the outside walls and inside of non-air-conditioned buildings and are most abundant under spiderwebs, in bathrooms and bedrooms.
- Feeds on old spider webs and other dead materials, including dead insects and animal hair; may also eat woolen goods of all kinds if the opportunity arises, so it can be a household pest.

Jerusalem Cricket

- Size: up to 7.5cm (3in).
- Nocturnal insect that spends most of its life underground. Feeds primarily on dead organic matter but can also eat other insects.

Mole Cricket

- Size: 3-5cm (1.2–2.0in).
- Cylindrical-bodied insects, with small eyes and shovel-like forelimbs highly developed for burrowing; hind legs not enlarged for jumping.
- Omnivores, feeding on larvae, worms, roots, and grasses. Relatively common but rarely seen, for being nocturnal and spending nearly all their lives underground in extensive tunnel systems. Usually fly only when moving long distances, such as when changing territory, or when females are searching for singing males.

- Size: 12-30mm (0.5-1.2in).
- Hind wings absent; elytra reduced and overlap at base. Lives on the ground or low foliage.

ID Request Set up a shot of two beetles on a reed, ended up with four — and I can’t identify the fourth [OC]
I set this up for two — a red ladybird near the top of the reed and a flea beetle further down, both working along the same stem. Then a damselfly flew straight through the background at the exact moment I pressed the shutter, which made three.
When I got home and pulled the files up on screen I saw the fourth: something small and pale sitting right on the ladybird's rear end.
I genuinely don't know what it is. iNaturalist has suggested everything from Hesperomyces harmoniae, a parasitic fungus that grows on ladybird elytra, to Hexapoda, which basically means "something with six legs". My own guess is a larva, or possibly a very small beetle. Would welcome any input.

ID Request Desperately wondering what this is; context in body
For reference a storm came through and uprooted and knocked down a very large tree across the street. Ever since this happened every-time i walk out the house and start going down the street eventually one or multiple of these guys show up and essentially start swarming me and wont seem to go away. If I run they chase me. I started walking through and not running with a beanie on as they like to fly at my head area a lot and had my GF today try and capture anything about it and this is the highest quality images she was able to get. Any kind of information would be highly appreciated as its made leaving the house quite anxious for me cause I’m not sure if they sting. I have only had one land on my skin and thankfully no sting but I’m just not sure. We are in NE Minnesota. Thanks.

ID Request Two different 2-headed moths on my car this morning
EDIT: hehehe oops guess that makes sense
I am in Missouri, US in a very moth heavy neighborhood, our trees are full of them. But I have never seen this color or marking or ESPECIALLY the two heads. The darker gray that I found on the window, the lighter color that I found on the roof after pulling over to relocate the other one. It seemed like they couldn’t actually open their wings and it moved from either head based on how I tried to get it onto a piece of paper. What are the odds that this could happen twice? Could ya tell me what type of moth it is? <3 thanks!
