The common birdwing is amongst the largest and most beautiful butterflies in Asia. The dramatic contrast of golden yellow hindwings and glossy black forewings gives this species a striking appearance, and serves as a protection mechanism by warning potential predators that it is distasteful. The upper surface of the golden hindwings features black borders and veins, with females additionally possessing a row of large, triangular black spots. A prominent pink saddle distinguishes the caterpillar of this species, and the pupa has a leafy appearance that helps to camouflage it from predators.
