The Common Jay (Graphium doson) is a black, tropical papilionid butterfly with pale blue semi-transparent central wing bands that are formed by large spots. There is a marginal series of smaller spots. The underside of wings is brown with markings similar to upperside but whitish in color. The sexes look alike.
It is widespread and common throughout Southeast Asia, including lower elevations in Sri Lanka and Southern India, Eastern Ghats, Satpuras, Bengal Assam and Bangladesh, and the Himalayan foothills. The species is however scarce in southern Honshū, Japan.
Common in thick, riparian, moist, deciduous, semi-evergreen and evergreen forests.
The Common Jay is active throughout the day and constantly on the move; it rarely settles down. Its flight is swift and straight.When feeding from flowers, it never settles down, and keeps its wings vibrating. The males are seen mud-puddling, often in tight groups.
