Pipevine Swallowtail

The Pipevine Swallowtail Butterfly (Battus philenor) is a swallowtail butterfly which is found in North and Central America.

The butterfly ranges from southern Canada southwards across USA to Mexico, Tres Marias islands and onto Guatemala and Costa Rica.

In the United States, the butterfly is found in New England down to Florida, from Southern Ontario (Canada) to Nebraska, Texas, Arizona, California, Oregon and New Mexico.

The upper surface of the hind wings of the male butterfly has an iridescent metallic blue sheen. The hindwings also have a series of pale, arrow-head markings above and a single row of seven round orange spots, which never touch, set in an iridescent blue field below.

The forewings are dull blackish-brown.

After mating, females lay batches of eggs on the underside of the leaves of a host plant. The caterpillars feed in small groups when young, but become solitary when older. Chrysalis overwinters.
