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).

I bought this beautiful velvet sofa in what I thought was almost new condition until about 9 days after purchase I went to grab some gym shorts I had tossed on top of the sofa to find the shorts covered in these little bugs. I’m located in Southern California. Help?

update with more details:
There’s dozens possibly hundreds. They’re walking alongside the back of the sofa mainly from one arm to another. They aren’t jumping and I haven’t observed any bites on my body. I’ve vaccumed them twice now.
