Mealworm
A tan, segmented larva with a shiny hard exoskeleton that tunnels through stored grain and flour before transforming into a darkling beetle.
caterpillar-larva
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
Soil Mite
A microscopic, heavily armored mite found by the millions in a single handful of soil, quietly breaking down leaf litter and helping build the fertile ground beneath forests and fields.
arachnid
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
Grub Worm
A plump, C-shaped, creamy-white larva with a distinct brown head, living underground where it feeds on grass and plant roots before eventually maturing into a scarab beetle.
beetle
White Grub
A pale, C-shaped larva with a brown head capsule and six stubby legs, spending its entire early life hidden underground feeding on roots before emerging as a stout May or June beetle.
beetle
Jewel Bug
A living gemstone of the insect world, the jewel bug shimmers in dazzling metallic greens, blues, reds, and golds. Its enlarged shield-like back covers the entire body, making it look like a polished piece of enamelware.
true-bug
Metallic Wood-boring Beetle
The North American common name for jewel beetles, emphasizing the wood-tunneling habits of their larvae, which leave telltale flattened, D-shaped exit holes in bark of stressed or dying trees.
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.
fly
Potato Bug
A rounded, boldly striped beetle in cream and black that feeds on potato and other nightshade foliage, easily recognized by the ten black stripes running down its wing covers.
beetle
Colorado Potato Beetle
A rounded, boldly striped yellow-and-black beetle that is one of the most notorious defoliators of potato plants, easily spotted marching across leaves in gardens and fields.
beetle
Two-Spotted Stink Bug
A boldly patterned black-and-orange predatory stink bug named for the pair of dark spots on its back, best known for hunting Colorado potato beetle larvae in gardens and fields.
true-bug
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
Black Vine Weevil
A flightless, all-black snout beetle notorious for notching the edges of leaves at night while its underground larvae feed on plant roots and crowns.
beetle
Bess Beetle
A large, glossy jet-black beetle that lives in family groups inside rotting logs, communicating with fellow beetles through squeaks and cooperating to raise larvae, an unusually social lifestyle for an insect of its kind.
beetle
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
Carpet Beetle
A tiny, rounded beetle with a mottled scale pattern of white, brown, and yellow, whose bristly larvae are known for feeding on wool, fur, and other dried animal fibers indoors.
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
Emerald Ash Borer
A slender, bullet-shaped beetle with brilliant metallic-green coloring, whose bark-tunneling larvae feed almost exclusively within ash trees.
beetle
Powderpost Beetle
A small, slender reddish-brown to dark brown beetle whose larvae tunnel through seasoned hardwood, reducing it internally to a fine, powdery frass.
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
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
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
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.
