Adults feed on the foliage of trees and shrubs at night. Larvae (grubs) live in the soil and feed on the roots of grasses and ornamental plants.

Behavior Patterns

Nocturnal insects that are strongly attracted to bright lights. They typically emerge in late spring or early summer to mate before females return to the soil to lay eggs.

Risks & Benefits
