See this bug in the Encyclopedia

Natural Habitat

Found in forests, thickets, and vineyards across North America.

Diet & Feeding

Adults feed on the leaves and fruit of wild and cultivated grapevines; larvae (grubs) eat decaying wood in old stumps or logs.

Behavior Patterns

Active during the summer months and attracted to lights at night. They are clumsy flyers and go through complete metamorphosis (egg, larva, pupa, adult).

Risks & Benefits

Generally harmless to humans; they do not bite or sting. While they feed on grapevines, they are rarely numerous enough to be considered a major agricultural pest. Larvae assist in decomposition of wood.
