Common Emigrant
Catopsilia pomona
The Common Emigrant, is a medium-sized butterfly found in Asia and parts of Australia. The upperside of the male is chalky-white, sometimes with a more or less broad and clearly defined basal sulphur-yellow area on both fore and hind wings; this sulphur-yellow colour is at times diffused over the whole surface of the wings, though generally it becomes paler towards the terminal margins.
