Red-bodied swallowtails are butterflies in the Swallowtail family, that belong to the genera Atrophaneura, Byasa, Losaria, or Pachliopta. They are generally found in Asia (Indomalaya ecozone).Collectors have found the red-bodied swallowtails difficult to kill. Pinching the thorax, a method which kills most butterflies, is withstood and apparently only stuns the butterfly temporarily.
