Zemeros flegyas   Adrian Hoskins

This very attractive little butterfly, and its relative emesoides are the only 2 species in the genus Zemeros.
Zemeros flegyas is found in India, Myanmar, Thailand, West Malaysia, Sumatra, Borneo, Java, Sulawesi and Bali.
This species is found in forest edge habitats at elevations between 0-1800m but is most abundant between about 500-1200m.
The egg is white, smooth, and laid singly on the underside of leaves of the foodplants Maesa chisia and M. montana ( Myrsinaceae ).
The caterpillar is ovoid and very flattened. Each body segment is rounded, giving it a corrugated appearance. It is pale green in all instars, and covered in short setae.
The chrysalis is smooth and light green in colour, marked with small suffused dark green spots and dashes. It is attached by a silken girdle to the underside of a leaf.
Adult behaviour
Both sexes are invariably encountered singly, usually in open forest edge habitats, including in quarries, regenerating forest clearings, along roadsides and in village gardens. They often visit flowers, either at ground level or on bushes.
Males sometimes imbibe moisture from the ground, but are usually seen when perched on foliage in their characteristic posture, with wings held half open and the forewings canted forward.
