This Caterpillar is initially just pale greenish-yellow. As it develops, it gets pairs of black warts along its back and sides. In later instars these are joined by black lines running along the body. The caterpillar feeds on:
The pupa is often yellow with black-edged spikes. It has a upcurved spike on the head, a pair of sideways spikes on the thorax. There are a pair of black warts along the body on each segment. The pupa is held by cremaster and girdle on the top or underneath a leaf.
The upper surfaces of the forewings of the adult butterflies are grey fading to white toward the margins, with a black apex containing white spots. The hindwings have irregular black margins fading to white at the bases.
The undersides of the forewings are grey, black, white and yellow. The undersides of the hindwings are dark grey-brown, each with a dark band. The butterflies have a wingspan of about 5 cms.
The adult male butterflies are keen on "mud puddling": collecting around puddles of mud and drinking the liquid.
The pale yellow eggs are ellipsoidal, ribbed, and laid singly, standing on one end, on a foodplant leaf
