Pipevine Swallowtail

Battus philenor

Also known as Blue Swallowtail

Pipevine Swallowtails flash iridescent blue across otherwise dark hindwings, with orange spots brightening the underside. Caterpillars feed on pipevines and retain defensive plant compounds that make them distasteful to many predators.
