The Spicebush Swallowtail is a common black swallowtail butterfly found in eastern North America. Also known as the Green-Clouded butterfly, it derives its name from its most common host plant, the spicebush.

The Spicebush Swallowtail belongs to the Papilionidae family of butterflies, which include the largest butterflies in the world. The swallowtails are unique in that even while feeding, they continue to flutter their wings. Unlike other swallowtail butterflies, Spicebushes fly low to the ground instead of at great heights.

The spicebush caterpillars look like small snakes, complete with large eyespots. They hide in folded leaves during the day and come out to feed in the evenings.
