Natural Habitat

Diet & Feeding

Adults feed on tree sap, rotting fruit, and plant juices; larvae (grubs) consume decaying wood and plant matter.

Behavior Patterns

Nocturnal insects attracted to artificial light sources. Males use large mandibles to wrestle rivals for mates. Complete metamorphosis (egg, larva, pupa, adult).
