Trogonoptera trojana

The Palawan birdwing or triangle birdwing (Trogonoptera trojana) is a birdwing butterfly of the family Papilionidae. It is endemic to Palawan in the Philippines. It is one of only two species in its genus, the other being the more widespread Rajah Brooke's birdwing, where the male has larger green markings on the hindwings. This species is included in CITES Appendix II,[1] restricting international export to those who have been granted a permit. The wingspan is approximately 18–19 cm (7.1–7.5 in).[1] The species may be observed flying at any point during the year. The larvae feed on Aristolochia.[1]
