Fruit Fly (Mediterranean)
A small but strikingly patterned fly with mottled, banded wings held out to the sides in a fan and a body dotted with silvery spots, best known for larvae that tunnel through ripening fruit.

Funnel Weaver Spider
Nearly invisible until dew or morning frost outlines it in silver, the funnel weaver's sheet-and-tunnel web is a familiar sight across lawns and gardens, with its owner watching from the safety of a silken tube.

A tiny, pale golden moth that avoids light and flutters weakly from dark closets, more often noticed by the damage its larvae leave in stored fabrics than by the moth itself.
moth
Dung Fly
A hairy, often golden-hued fly commonly seen perched on fresh manure in pastures, where it hunts smaller insects as an adult while its larvae develop within the dung itself.
fly
American Carrion Beetle
A broad, flattened black beetle with a striking pale yellow shield behind its head, commonly found on and around small animal carcasses where it feeds alongside fly larvae.
beetle
Common Clothes Moth
A tiny, plain golden-buff moth that rarely flies far into open light, best known not for its adult form but for its silk-spinning larvae that chew holes in wool, fur, and feathers.
moth
Gall Midge
A delicate, mosquito-like fly whose larvae trigger plants to grow strange, often colorful swellings called galls, each species usually tied to one particular host plant.
fly
Burying Beetle
A black beetle marked with bold orange-red bands, notable for locating small dead animals, burying them underground, and cooperatively raising larvae with a partner over the buried carcass.
beetle
