Papilio epiphorbas (female)
 
Papilio epiphorbas, the teardrop swallowtail, is a swallowtail butterfly that is endemic to the island of Madagascar. Because of their obscure and endemic  nature, they are not commonly bred or reared. While literature is lacking, they are rumoured to feed on Vepris (Rutaceae – unconfirmed). In captivity they will accept Citrus or Choisya, though one may experience significant losses when rearing them on these host plants – some individuals will still survive. Perhaps, by selecting these individuals, one may produce a F2 generation that has adapted better to Choisya or Citrus, making them easier to breed
