Papilio bianor, the Chinese peacock black swallowtail emerald[1] or Chinese peacock, is a species of butterfly in the family Papilionidae, the swallowtails.[2] It is native to Asia and Australia.[3]


This species is variable in size. Individuals emerged in the spring reach 4 to 8 centimeters wide, while those emerged in the summer can reach 12 centimeters.[1] The forewings are black with dark veining and green scales. The undersides are brown, turning white distally with dark veining. The hindwings are tailed and have ridged edges containing reddish eyespots. The body is black with green scales.[3]

The male has black hair on the forewings, which the female lacks.[1]
