The larva is usually light green, but sometimes whitish green too, with a backbone-like mark in varied combinations of light maroon, dark green and yellow, from the head to the end of its body. The creature, like most other species, consumes the leaves of its host plant, as well as the flowers.

The chrysalis is light brown with random dark spots all over its body. The combination of colors and the texture of its body cover give it the look of a dead or dry leaf. This adaptation helps them stay camouflaged throughout this stage.

Adult Butterfly

Sexual Dimorphism: Prominently present

Color and Appearance: When the wings are open, the dorsal surface in a male looks pale blue along with a fine dusting of white scales all over the four wings. Some females have white in place of blue. In such cases, there is a hint of blue at the bases of the wings. The forewings of most females, however, have a wide dark grey band on the costa and the outer third. When the wings are closed, the ventral side is somewhat chalky white to dull grey accompanied by very small grey spots along with a submarginal line on the hindwing.
