Natural Habitat

Found in meadows, woodland edges, gardens, and leaf litter across much of North America.

Diet & Feeding

Caterpillars feed on many herbaceous plants, including grasses, asters, clover, and garden plants; adults do not feed extensively.

Behavior Patterns

The densely hairy larva often wanders openly while searching for food or a pupation site, especially in autumn. It overwinters as a larva or pupa and later emerges as a white moth with dark spots.

Risks & Benefits

Its hairs are generally non-venomous but may cause mild skin or eye irritation in sensitive people. It is harmless to people, supports insect-eating wildlife, and contributes to plant decomposition and food webs.
