The Ceylon birdwing is one of the largest butterflies of Sri Lanka. Like most other Troides birdwings, the male is adorned with bright golden-yellow markings on the hindwings, which contrast starkly with the velvety black forewings and interjecting black veins. The female is larger than the male, and has a different arrangement of yellow markings on the hindwing, and pale stripes on the forewing. |
