Pipevine swallowtail butterfly
Found throughout North and Central America, this beautiful butterfly (Battus philenor) boasts black-brown wings and body with iridescent blue coloration and white dots along the hind wings. The underside of the wings has the same metallic blue quality with a half circle of seven orange spots. Males tend to have brighter iridescence than females.
As caterpillars, the species feeds on the pipevine plant (Aristolochia), which makes them poisonous in both their larval and adult or imago state. And if you hadn't guessed, it's also the reason why they're called pipevine swallowtails!
Pipevine swallowtails are often confused with mimic species such as the spicebush swallowtail, black swallowtail or the dark-morph of the Eastern tiger swallowtail.
