Pipevine Swallowtail (Battus philenor) life cycle
Larval hosts: Aristolochiaceae - pipevine family
Texas Swanflower (Aristolochia erecta)
White-Veined Dutchman's Pipe (Aristolochia fimbriata)
Marsh's Dutchman's Pipe (Aristlochia pendrata aka Aristolochia marshii)
Am assuming there are other pipevine species used by the Pipevine Swallowtail but those are the only one's I am familiar with that they use down here.
This is a male Pipevine Swallowtail - note the iridescent blue on the hind wings
