Caterpillar Identification Guide

American Lady (Vanessa virginiensis) caterpillar

Common Name: Acadian Hairstreak

Genus-Species: Satyrium acadica

Host Plants: Various willow species including black willow (Salix nigra) and silk willow (Salix sericea).

Habitat: Wetland areas, especially marshes, with an abundance of willow, the host plant of this species.

Comments: The Acadian Hairstreak often perches on the tops of vegetation, usually near a good patch of willows, its host plant. This makes fresh, light gray Acadian Hairstreaks often easy to spot.
