A tiny, teardrop-shaped tick with dark legs and a reddish-brown abdomen that lurks in leaf litter along woodland trails.

Small and delicate, bluet damselflies flash brilliant blue and black along the vegetated edges of ponds and lakes, forming mating pairs that fly in tandem while laying eggs directly into plant stems underwater.

A pinhead-sized wasp that spends nearly its entire life inside a fig, forming one of the most tightly co-evolved partnerships in nature as it pollinates the tree in exchange for a place to lay its eggs.

wasp
Ichneumon Wasp

Ichneumon Wasp

A slender, long-antennaed parasitoid wasp, often mistaken for a giant mosquito or a stinging insect, that is best known for the extraordinarily long ovipositor some species use to drill into wood and lay eggs on hidden larvae.

wasp
Western Honey Bee

Western Honey Bee

The familiar golden-brown, fuzzy-banded honey bee kept worldwide for honey production and crop pollination, living in large perennial colonies built around wax comb and a single egg-laying queen.

A small, flat, reddish-brown, wingless insect shaped like an apple seed that hides in mattress seams and bed frames by day and emerges at night to feed.

true-bug

The largest centipede on the planet, a formidable dark reddish-brown predator from South American rainforests capable of capturing prey as large as bats and small reptiles.

myriapod
Clover Mite

A speck-sized reddish mite that streaks a rust-colored stain if crushed and invades homes by the hundreds when lawns dry out or turn cold.

arachnid
Woodlouse Spider

Woodlouse Spider

A reddish-brown spider with oversized forward-pointing jaws specialized for piercing the armored shells of woodlice, often found lurking under damp stones and mulch.

arachnid
Ruby Tiger Moth

A plain tan to reddish-brown moth whose caterpillars are famous for marching in large groups across fields, stripping grasses and grain crops as they move.

moth
Warble Fly

Warble Fly

A furry, bee-mimicking fly that never lands on flowers or feeds as an adult, spending its brief life darting around grazing cattle to lay eggs on their legs and lower body. Herds sometimes react with sudden panicked runs, known as gadding, whenever a warble fly approaches.
