Necrophila americana Linnaeus, 1758. The common name for this species is American carrion beetle. Adults arrive at a carcass shortly after the first flies arrive (just after the animal has died) and lay eggs. Larvae feed on on the decaying carcass as well (and oftern consume other larvae). The larva burrows into the soil, and forms a pupa. Adults overwinter in central Illinois. This specimen was collected by Mark DuBois in Marshall Co., Illinois.
