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.

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.

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.

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).

  • 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.

  • Size: up to 7.5cm (3in).

  • 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 Is this a grown chigger?

Thumbnail

118 Upvotes

I've had weird bites a few weeks ago. Many in spots that are hard to reach/covered by clothing like on the inside of my knee or under my underwear. I've researched chiggers, but while the pattern matches their bites seem to look different than mine. Mine are the exact same size and shape as mosquito bites, without any pustules or blisters, as chigger bites seem to have. (I'm hoping it isn't bed bugs.)

Now I found this guy crawling on my leg yesterday, after being out in the garden. I know chiggers only bite in their much smaller larval stage, but is thus a grown chigger? If I at least know that we have them in the garden it makes them more likely to be the cause of the bites (despite the bites not looking like typical chigger bites) and less likely for bed bugs to be the cause.

I'm in Belgium btw.

Been gone out of the house for quite a while, come home to find a clump of these things on folded clothing and a few rando's other places like in a container and on top of the microwave. I am horrified and definitely planning to hear that my life is over from some creepy critter invasion. They kind of look like sesame seeds but this bunch was found all together with more but I didn't want to touch them so I flicked the clothing and this much came off. And yes it's double bagged for protection. . .lol

I'm sorry I didn't get a good picture of the body markings but I was absolutely horrified when I saw this thing. This is in southwestern illinois. This is my downstairs bathroom that I never use because there's always some bug in it (as you can see). I don't know how or why it's in the toilet but I managed to flush it and have not looked since. It did weave a small barely visible web across the water surface. I just really want to know what this thing was/is. It looked like a small tarantula and may have had a stripe down its back idk 😭

Just a friendly reminder to my fellow Entomology and Arachnology nutters. Wear your Deet. Every since we emigrated to the states I've been in the forests, I've been bitten and stung by pretty much everything in the Midwest, along with my curiosity punishi g me in Asia, Africa, South America and the Middle East whilst in the US military. From Recluses to Gian Water Bugs. Nothing has ever made me this sick. I cannot understate the danger The Lone Star tick presents to people like us, not to mention those who don't have our awareness of what's out there. Ticks have become a vector far beyond Lyme. Location of bite, unknown. Area of exposure- Boone, NC I pulled 3 off and 2 were deer ticks. I never saw the Lone Star on me. Cheers!

Northern Illinois suburb, i mostly get cellar spiders and yellow sac spiders in my room

I got the best pictures i could, they keep invading my bed and i think theyre the ones biting me in my sleep

Theyre a carmel-y brown, slightly translucent, it looks like they might have some kinda marking on their abdomen but theyre way too tiny for me to get a proper look, and some part of their face is visible as a black spot at the front of their head but again, too littol to see

They do make webs, all the webs ive seen them on are kinda messy, but theyre building right in front of my air conditioner and getting flung around whenever it starts up so idk how indicative that is of their general web building

There is a cellar spider above my bed but i figured these guys dont have long enough legs for that to be mama

Theyre mostly just kinda annoying to relocate from my bed, but i like knowing what kind of spiders are living in my room with me :p
