These Caterpillars are green fading to yellow at each end, and have pale yellow lines along the body. They are thought to feed on various species of Elm (ULMACEAE) including :
They feed particularly on young shoots of the foodplant. When not feeding, they rest with the thorax lifted and the head curled underneath.
The pupa is green or brown with a yellow line along each side. Its length is about 1.5 cms. It is formed hanging obliquely, head downward, from the underside of a foodplant leaf.
The wings of the male and female adult butterflies are different.
The males are purple with brown veins and dark wingtips. The forewings have several white spots. The hindwings each have an indistinct orange band.
The females are brown, shading to orange at the base of each wing, and with white spots on the forewings. There is an orange band across each hindwing.
The undersides are similar to the upper surfaces but suffused with white . The wingspan of the butterflies is about 5 cms.
The eggs are pale cream, and elongate. Their height is about 0.7 mm. They are laid singly in a crevice, such as a leaf axil, of a foodplant.
The species is found as several subspecies throughout south-east Asia, including:
and in Australia, where it is confined to the northern tropics, with two subspecies:
