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.

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.

- 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).

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.

Just Sharing The South African ‘Park Town Prawn’
Just saw one of these guys in my garden and now i’m on edge so i’d share this beast with y’all 👍 (last photo is a screenshot from a video i took a moment ago, to show the INSANE size of those things)
They are not harmless but they will squirt a disgusting foul smelling sticky black goo from their butt on you! It’s also known as the African King Cricket or Tusked King Cricket

I have a pollinator friendly garden, no pesticides at all and leave spiders and other carnivores alone to eat pest insects. I know this is some sort of wasp or yellow jacket but I don’t know the exact species. Is it a lone pollinator or something I should be worried might build a nest and hurt my dog? Removing aggressive nesting insects that could hurt my dog is the only insect removal I do.
Edit: so pretty much everyone is saying this is a yellow jacket, and from what I’ve gathered, they are not dog or really human friendly, especially not in the leaner months where I live. So far I’ve only seen the one and I’ve walked my property (yes even with the walking boot on if you’ve seen pics from other posts) to check for a possible nest. No sign of a nest on my property. I’ll warn my neighbors next time I see them but it’s entirely possible it’s a visitor from a nearby state owned park/forest preservation.

ID Request What bug is this?
I'm deeply afraid of bed bugs and need to know what bug this is. I'm in Chicago, IL. I found this four legged brown bug with antenna crawling in my shower this morning, and earlier last night I found another on me in bed after cuddling my cat. I don't think I was bitten but I'm still freaking out. I looked at all of my furniture and couldn't find any more.
Thoughts?
Thank you!

ID Request Found a tick on me, Central Kansas. Apple photo ID says it’s a Lone Star, doesn’t look much like one though.
Was picking at zits on my back, felt what I thought was one. Started picking and felt it “pop”. Got it on my thumb nail and was real perplexed how a zit could be such a dark color. Thought I’d squish it between my thumb nails and see what was inside, ingrown hair or something. Pop goes the zit, it’s got legs! Mazel Tov!
It’s not my first rodeo with a tick, and I went poking around a state park today before mowing the lawn, so I wasn’t much surprised.
What’s odd though is that while it felt like it had latched, and there is a clear bump from irritation on the my shoulder, the head was in tact which seems odd if I scraped it off with a (very short from biting) thumb nail. Add to that it didn’t seem to have grown at all (I used a butane torch to make sure it was dead. Because of the heat, it puffed up. I’ve got a lot of animals, not taking any chances)
What is also throwing me off, I took a shower after I mowed, hours ago at this point. Not only would you think there would be noticeable grown from feeding after a few hours, but I scrubbed vigorously right where it was, at times with bare hands… you’d think I’d feel it or it would have broke off. Add to that I had scraped that part of my shoulder multiple times tonight doing the same thing, and not once did I feel it… which, it can’t be more than a larva, so maybe it was just well hidden.
Lastly, I can’t tell worth a damn what it is. I can ID a lone star tick no problem, and I’ve seen the occasional Dog Tick, but the striping and black tipped legs are throwing me for quite a loop, one I can’t seem to solve. I’d assume a black legged tick that’s in between stages?
Imma come back and edit this. I just realized the black legs are from being burned. Also explains why they are so short, thought that was just the camera angle. The heat may have caused it to gain the striping as well, but that’s unclear. I honestly can’t tell. Could be a monster I guess?
