The Common Posy is a relatively common forest butterfly, usually found individually in localised areas. It can usually be found along jungle paths near sunlit spots. It returns to a same leaf to rest, time and again. The males have bright blue hindwings above whilst the females are greyish white on the hindwings above. The underside of the forewing is orange, and the distinctive black-barred hindwings distinguish it from the Branded Imperial. The butterfly has 3 tails, of which the middle one is the longest.
