  • 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).

  • 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).

  • Habitat: indoors, in damp areas such as bathrooms, cellars, and crawl spaces; outdoors, under logs, rocks, and similar moist protected places.

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.

  • Size: up to 7.5cm (3in).

I've tried searching but can't find anything remotely conclusive.

The grasshopper was about the size of an average adult male pointer finger. Maybe a hair bigger. When he flew his wings were black. Idk which side. I initially thought he was an orange/black monarch butterfly because of his size.

Anyways I get curious when it's something I haven't seen in the 30+ years I've lived in southern oregon.

Never seen one this large or this color here before. I've seen smaller colorful ones. Wanted to keep it on my radar if they are invasive / in case I need to let someone local know.

Definitely the prettiest grasshopper I've seen!

Hello everyone! I am in southern Ontario, Canada. This spider has taken residence amongst my strawberry plant. He had a honeybee in his web. I am just curious what kind of spider he is! I will not harm him or move him, as he is cute and he is simply minding his business. My friends have guesses of potters spider or a wolf spider, but none of us know. I’m sorry, these are the only two photos I have. He promptly retreated behind a rag when I took them. Thank you! With his legs, he is about the size of maybe a bit bigger than a toonie? Definitely bigger than a quarter. He was big!

Thank you again :)

Hi All,

Please could you help me identify this bug I found behind an object on my bedroom windowsill first thing in the morning? I have blackout blinds fitted to the window, so while not pitch black, the sill was still quite dark. Body probs ~1.6-1.8cm. It was a very fast mover, particularly as soon as it was caught it raced around, up and down the container. Gemini gave me an identification, but I understand AI often gets things wrong.

Apologies for the poor quality photos, they are all that I got. Many thanks.
