A large dark swallowtail washed with blue-green on the hindwings, the spicebush swallowtail is a butterfly of eastern woodlands and their edges.
Adults nectar on Joe-Pye weed, thistles, and honeysuckle, and like the pipevine swallowtail they gain protection from a dark, warning-colored pattern.
Its caterpillar is famous: green with large false eyespots that make it resemble a small snake, it feeds on spicebush and sassafras and shelters in a folded leaf.
