Natural Habitat

Found in coniferous and deciduous forests, woodlands, and suburban gardens across North America.

Diet & Feeding

Adults do not eat as they have vestigial mouthparts; larvae (caterpillars) feed on various trees including pine, oak, maple, and sweetgum.

Behavior Patterns

They are nocturnal and attraction to lights is common. Larvae go through five molts and can vary significantly in color; pupation occurs in an underground chamber rather than a cocoon.

Risks & Benefits

Harmless to humans; they serve as a food source for bats and birds and are a beautiful indicator of a healthy local ecosystem.
