Necrophila americana

American carrion beetle

This beetle's yellow-and-black pronotum makes it look like a bumblebee in flight, though it heads for compost piles and carcasses instead of flowers.

The American carrion beetle has an oval, flattened body with a pale yellow pronotum marked by a large black spot in the center, over black wing covers. Its larvae are dark, teardrop-shaped grubs that look something like sowbugs.

Adults and larvae gather at carrion and rotting matter, where they feed on fly maggots as well as decaying tissue, and mites that ride along on the beetles get an early start on the same fly eggs and larvae once they arrive at a carcass. Females lay their eggs directly on a dead animal after it has begun to dry out.
