• Battus

  Pipevine Swallowtails and Allies

  Battus is a New World genus of swallowtail butterflies in the family Papilionidae. The genus comprises approximately 9 species distributed across the Americas, with the most well-known North American representatives being Battus philenor (pipevine swallowtail) and Battus polydamas (Polydamas swallowtail). All members share a specialized ecological relationship with pipevine plants (Aristolochia), which serve as their exclusive larval host plants. The genus is notable for its aposematic coloration and chemical defense system derived from sequestered toxins.
