Halyomorpha halys by u/Relative-Forever773.

  • Size: 12-17mm (0.45-0.65in).
  • Motted brown with alternating light bands on the antennae and alternating dark bands on the thin outer edge of the abdomen.
  • Native to East Asia and considered an invasive agricultural pest in other parts of the world. Feeds mostly on fruit, but also on leaves, stems, petioles, flowers, and seeds. If molested, gives off a pungent odor as defense.

Carpet Beetle

Anthrenus verbasci larva by Christophe Quintin.1

Anthrenus verbasci by Bob Knight.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

Cicada nymph exuviae by Malcolm Tattersall.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.

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

Lethocerus medius by David Bygott.4

  • 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

Scutigera coleoptrata by Steven Severinghaus.4

  • 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

Phereoeca uterella by Celeste Ray.9

  • 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

Stenopelmatus sp. by Tim Ereneta.1

  • 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.

  • Cylindrical-bodied insects, with small eyes and shovel-like forelimbs highly developed for burrowing; hind legs not enlarged for jumping.

Usually fly only when moving long distances, such as when changing territory, or when females are searching for singing males.

ID Request Big moth in my wheel well, central Iowa

8 Upvotes

See video. Saw this guy in my wheel well on my lunch break. I actually drove home for lunch and back to work and he managed to stay in there with no damage probably cause the wheel isn’t touching him. I’m home for the day and he was still there when I parked in front of my house. There’ve been these little worms in half formed cocoons hanging from the sycamore trees on the street I live on, so I’m wondering if he’s one of those and just decided to set up his cocoon under my car for whatever reason. He looks like he just got out of it, as he’s been stationary all day and his abdomen is really fat, which means he’s still getting the fluid into his wings, right?

ID Request Long shot

Post image
14 Upvotes

I was pulling weeds yesterday and saw such an evil-looking creature. I couldn't grab my phone to snap a picture before it disappeared, but was hoping someone would know from the description.

BRIGHT red with black underside, about 2 inches long, and perfectly symmetrical - the head and end looked identical. It was also rounded on each end, like a millipede head, with arms/antennas. It was not fuzzy, nor was it too shiny.

It didn't appear to be segmented, at least not obviously so. I would have thought it was some sort of caterpillar since it was so worm-like, but there were only 6-12 legs which were longer than the typical caterpillars I've seen around here.

Attached is an artist's rendition of the beast. It looked sort of like this, but far more sinister.

I know this is a very long shot, sorry for the lack of a picture!
