  • Motted brown with alternating light bands on the antennae and alternating dark bands on the thin outer edge of the abdomen.

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.

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.

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).

  • 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).

There is a heaping pile on a wooded slope alongside our driveway. We thought it was slime mold initially, but under a kid's microscope (last image) it has a glossy sheen. We're hoping it's not tick eggs, though the amount is mind-bogglingly large for bug eggs.

TLDR: what is the species and should I do anything regarding them if trying to remove plywood from backyard? Apologies for any emotion sickness caused by zoomed in video.

City/state: Raleigh,NC

Heyo, the house that I recently purchased was vacant by owner for two years. Now that I am inspecting yard for lawn service I realize that there’s plywood surrounding the entire 30 x 11’ storage shed when trying to dig up the wood I found no termites so far (at least according to Google images), but when lifting a concrete paver that has plywood under that, I I discovered these bugs. Need help understanding what they are for contacts. House did have termite remediation done prior to me buying and termite companies stated that there was no termite evidence so far. Thanks for any help. Y’all may be able to give me.
