Whitefringed Beetle
A stout gray-brown weevil named for the pale, fringe-like stripe along the outer edge of its wing covers, whose root-feeding larvae are a recognized issue in pastures and row crops.
beetle
Pleasing Fungus Beetle
A shiny, smooth-bodied beetle marked with bold red or orange bands on a glossy black background, commonly found feeding on bracket fungi growing on dead or dying hardwood trees.
beetle
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
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
Convergent Ladybird Beetle
A common orange-red ladybird with black spots and two distinctive converging white lines on its thorax, widely valued as a natural aphid predator.
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
Oriental Cockroach
A dark, matte blackish-brown cockroach with short wings that do not cover the abdomen, especially in females, and a preference for cooler, damper hiding spots than most other common cockroaches.

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
Ladybug
A small, round, brightly colored beetle with a domed, shiny shell typically red or orange with black spots, one of the most recognizable and beloved beetles found in gardens worldwide.
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
Emerald Ash Borer
A slender, bullet-shaped beetle with brilliant metallic-green coloring, whose bark-tunneling larvae feed almost exclusively within ash trees.
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
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
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
Carrot Rust Fly
A slender, shiny black fly barely a few millimeters long whose slim yellowish larvae tunnel rust-colored trails through carrot and parsnip roots.
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.
fly
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.
