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
Bordered Plant Bug

Bordered Plant Bug

A dark, oval-bodied true bug with a distinct pale margin around its wing edges, often mistaken for a large ant or beetle when its nymphs cluster together in tight groups.

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
Tachinid Fly

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.
