Natural Habitat

Found in hardwood forests, urban and suburban areas, and orchards across North America east of the Rocky Mountains.

Diet & Feeding

Larvae (caterpillars) feed on various trees and shrubs including maple, birch, cherry, and willow. Adults do not have functional mouthparts and do not eat; they live only to mate.

Behavior Patterns

They are nocturnal and predominantly active during the early morning hours. They exhibit a univoltine life cycle, producing one generation per year, and spend the winter in a silk cocoon attached to a twig.

Risks & Benefits

No risks to humans as they do not sting or bite. Benefits the ecosystem as a primary consumer in its larval stage and serves as a food source for bats and birds.
