False Barred Sulphur
Eurema elathea

f7.1 @ 1/1250s, ISO:640, Nikon D3S w 500mm

The upperside forewings of male Eurema elathea are yellowish, with a broad blackish-brown apex, and a broad straight blackish bar along the inner margin ( dorsum ). The hindwings of the male are white, with a broad dark brown border. This species can easily be confused with daira, but the latter has a slightly curved bar on the forewings, rather than the straight bar of elathea. Females of both species lack the bar. They have white forewings and hindwings, both with broad dark borders.
