Species of butterfly
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).[4][5] The butterfly was named by the naturalist Alfred Russel Wallace in 1855, after James Brooke, the Rajah of Sarawak.[5] The larval host plants are Aristolochia acuminata and A. foveolata.[6] Adults sip flower nectar from plants such as Bauhinia.[5] Rajah Brooke's birdwing is a protected species, listed under Appendix II of CITES,[6][7] meaning that international export is restricted to those who have been granted a permit. It is the national butterfly of Malaysia.[8]
