The Pipevine Swallowtail is a swallowtail butterfly found in North and Central America. The butterflies are black with iridescent blue hind wings. They are found in many different habitats, but are most commonly found in forests. The black or red caterpillars feed on Aristolochia species, making them poisonous as both larvae and adults, while the adults feed on the nectar of a variety of flowers.
