The Banded Grass Yellow, Eurema nicevillei (Butler)

Of all the species of the genus Eurema, this is one the least commonly encountered species. Occasionally, a lone or two specimen may be seen puddling en masse with the other members of the same genus. They can be easily distinguished once they take to the wings as this is the only species with a black distal border of the forewing that is continued along the dorsum to the base.

From this year's observation (2013), they seem to be commonest in the month of December, right after a period of heavy downpour followed by a break in the weather.
