Trogonoptera brookiana, Rajah Brooke's birdwing, is a birdwing butterfly from the rainforests of the Thai-Malay Peninsula, Borneo, Natuna, Sumatra, and various small islands west of Sumatra (Banyak, Simeulue, Batu and Mentawai). The butterfly was named by the naturalist Alfred Russel Wallace in 1855, after James Brooke, the Rajah of Sarawak. The larval host plants are Aristolochia acuminata and A. foveolata. Adults sip flower nectar from plants such as Bauhinia. Rajah Brooke's birdwing is a protected species, listed under Appendix II of CITES, meaning that international export is restricted to those who have been granted a permit. It is the national butterfly of Malaysia.
