Natural Habitat

Deciduous forests, woodlands, and gardens, often resting on tree trunks or wooden structures during the day.

Diet & Feeding

Adults feed on tree sap, rotting fruit, and nectar; larvae (caterpillars) feed on the leaves of specific host trees like oak, willow, or hickory.

Behavior Patterns

Nocturnal; they utilize crypsis (camouflage) to blend in with tree bark during the day. When disturbed, they flash brightly colored hindwings (often orange, pink, or red) to startle predators.

Risks & Benefits

Harmless to humans. They serve as essential prey for bats and birds, and the adults contribute to pollination in their ecosystem.
