Buru opalescent birdwing  (Troides prattorum)

Description

Confined to the island of Buru, Indonesia (4), this huge and spectacular black and yellow butterfly is named for the unusual, opalescent gloss of the male’s hindwing (4) (5) (6). The hindwings are golden yellow and display a striking iridescent blue-green sheen when viewed at an angle (2) (4). The hindwing of the female Buru opalescent birdwing is mostly suffused with black, but an iridescent sheen may be present on the restricted yellow areas (7).
