The tile-horned prionus, Prionus imbricornis Drury (22-50 mm) has a dark brown and shiny body. There are 18 to 20 overlapping segments found in the antennae in males with 16 to 18 serrated segments in females. The elytra is coarsely pitted. Females lay eggs at the base of deciduous trees and shrubs. The larvae bore into the roots of the trees and can cause extensive damage; their feeding activities lead to the hollowing out of larger roots. The larva takes 3-5  years to adulthood. The nocturnal adults are attracted to light and hide under loose bark during the day. This species is widespread in Virginia and is found in the central and eastern United States, as well as southern Canada.
