Crane Fly Larva
Thick-skinned and worm-like, the crane fly larva, often called a leatherjacket, burrows through wet mud and decaying vegetation at the edges of ponds and streams, breaking down plant material as it grows.

Isabella Tiger Moth (Woolly Bear)
Famous chiefly in its larval stage as the banded woolly bear caterpillar, this tiger moth's fuzzy black-and-rust-colored caterpillar is a familiar autumn sight, while the adult is a soft, tawny-orange moth with a stout, furry body.

Fireflies Larvae Glowworm
The larval form of fireflies, often called glowworms, are flattened, segmented crawlers that glow with a steady greenish light. These little predators hunt slugs, snails, and worms in damp ground.
beetle
Furniture Beetle
A tiny, reddish-brown to dark brown cylindrical beetle whose larvae, commonly called 'woodworm,' bore small round tunnels through seasoned furniture and timber.
beetle
Asian Lady Beetle
A highly variable orange-to-red ladybird beetle, often bearing many black spots or none at all, famous for swarming into homes in large numbers during autumn.
beetle
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.

Rootworm
Working unseen below ground, rootworm larvae chew tunnels through the root systems of corn and other crops, the underground counterpart to the small, often striped or spotted beetles seen on leaves and flowers above.
beetle
Mexican Bean Beetle
A copper-colored, spotted beetle resembling an overgrown ladybird that feeds on bean plant leaves along with its spiny yellow larvae.
beetle
Tachinid Fly
A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.

Predatory Stink Bug
Unlike its plant-feeding relatives, the predatory stink bug is a hunter that spears caterpillars and beetle larvae with a stout beak. The spined soldier bug is a familiar shield-shaped garden ally.
true-bug
Cottonwood Borer
A large, boldly patterned longhorn beetle in black and chalky white checkerboard markings, often found clinging to the trunks of cottonwood and poplar trees near its larvae's root tunnels.
