Vine Weevil
A slow, flightless, matte-black beetle that hides by day and emerges at night to notch neat semicircular bites from the edges of leaves.

Old House Borer
A grayish-brown to nearly black longhorn beetle whose larvae bore extensively through structural softwood, capable of causing large galleries hidden beneath the wood surface.
beetle
Stag Beetle
A large, glossy beetle whose males wield oversized, antler-like mandibles resembling a stag's rack of horns, used for wrestling rival males rather than for feeding.
beetle
Squash Beetle
A large, coppery-orange, spotted beetle that resembles an oversized ladybird but, unlike most of its relatives, feeds on squash and pumpkin leaves rather than aphids.
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
Longhorn Beetle
A beetle instantly recognizable by antennae often longer than its own body, ranging from small woodland species to large, dramatically patterned tropical and temperate forms.

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
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.
true-bug
Pine Sawyer Beetle
A large, long-antennaed longhorn beetle of pine and spruce forests, mottled gray-brown to black, that produces a rasping sound when handled and whose larvae tunnel deep into dead or dying conifer wood.
beetle
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
Spined Soldier Bug
A predatory stink bug identified by the sharp, pointed spines projecting from its shoulders, valued in gardens and farm fields for hunting caterpillars, beetle larvae, and other pest insects.
true-bug
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.
