The Common Birdwing Butterfly (Troides helena) is a large insect in the Papillionidae family of butterflies.
The male and female Common Birdwing Butterfly look slightly different. The male has black wings, with yellow on its hind-wings and one or more black spots. It has a black body with a yellow belly. The female has more obvious veins in her wings. Her hind-wings have a series of large, oval black spots. Her belly is dark-brown.
Its wingspan measures 13-16 centimetres (5-6.5 inches).
The Common Birdwing Butterfly is native to Asia, in countries such as Nepal, India, Bangladesh, Myanmar, Malaysia, Singapore, Indonesia, Laos, Cambodia, Thailand, Vietnam, and southern China. The photograph of the Common Birdwing Buttefly was taken in Siem Reap in Cambodia.
It prefers tropical and sub-tropical forests, and is also found in parks and gardens.
The female lays eggs on the leaves of plants, which hatch into caterpillars after 6 days. The caterpillars eat leaves and metamorphose into a green or brown-coloured chrysalis, which is a casing. The metamorphosis takes 3-4 weeks. After about 20 days, an adult butterfly emerges from the chrysalis.
The adult Common Birdwing Butterfly lives, on average, for 6 weeks.
