Hind-wing with a moderately broad black outer band. Underside. Both wings with more or less defined ordinary markings of wet form. Fore-wing with three marks in the cell, in addition to the discocellular. No sub-apical patch. Female. Not seen.

Intermediate form: Male. Not seen. Female. Upper-side. Fore-wing with similar outer band to the wet form. Hind-wing with a broad black outer marginal band. Underside with slightly-defined ordinary brown markings as in wet form. Fore-wing with a brown sub-apical patch.

Dry form: Smaller than in wet form. Male. Upper-side. Fore-wing with narrower outer marginal band, its posterior end much smaller. Hind-wing with a slender outer band. Underside. Both wings with similar ordinary markings to the wet form. Fore-wing with a more or less defined sub-apical patch. Female. Upper-side. Fore-wing with a broader black outer band than in male. Hind-wing with a much broader outer band than in male. Underside. Both wings similar to male.

Extreme Dry form: Male not seen. Female. Upper-side. Fore-wing with a broad black outer band, its posterior portion angled obliquely outward from the lower median veinlet.

Life Cycle

Egg

Pupa

After 20 days from the hatching , the larva become pupa. Pupae are light green in color and , they become butterflies and emerged from the chrysails after a week.

Food plants

Caesalpinia mimosoides and Bauhinia purpurea.[5]
