Papilio hospiton (Guenee, 1839)

No data. (presumed Corsica or Sardinia) Photo from Japanese web site no English text. female

    Endangered and known only from the islands of Corsica and Sardinia in the Mediterranean; It prefers mountain pastures over 600 meters elevation, and is under threat as farming destroys its hostplant (which is apparently poisonous to sheep). Extremely local. Phylogenetically it may be more closely related to the N American P polyxenes then to P machaon (based on RFLP DNA studies). Its closest relative is actually the North African Papilio saharae. It is listed as Appendix I of CITES, but some illegal trade undoubtedly still occurs (though this alone is unlikely to pose any threat).
