Description

[edit]

Wet-season form: Male. Upper-side somewhat paler yellow. Fore-wing with the outer marginal black band; the apical edge of costa and the cilia rosy-red. Hind-wing with the black outer band somewhat narrower, macular, the decreasing portions each with a more prolonged inner-tooth, and the yellow ground-colour between each extending to the outer edge. Underside pale yellow, the fore-wing also having a very slightly defined sub-apical inwardly-oblique squamous streak. Fore-wing with the entire costal edge and outer marginal cilia, and also the outer marginal cilia of the hind-wing, rosy-red. Female. Upper-side. Apical edge between the subcostals of fore-wing, and cilia of both wings paler rosy-red. Underside with the markings on hind-wing slightly visible. Fore-wing above with the black outer band broken beneath the lower median veinlet. Hind-wing with the outer band similar to male, its portions slightly broader. Underside similar to male, the markings being slightly more defined.

Intermediate form: Male. Upper-side. Fore-wing with the outer band slightly narrower than in wet form; cilia paler red. Hind-wing with the marginal macular band narrower, and composed of smaller portions. Underside similar to wet form. Female. Upperside. Fore-wing with the outer band less broken at its posterior end than in wet form. Hind-wing with the marginal macular band less distinct and narrower. Underside similar to the male.

Dry-season form: Both sexes much smaller than in intermediate form. Cilia paler. Male. Fore-wing above with the inner-edge of the marginal band less sinuated than in intermediate form, its posterior end indistinctly broken. Hind-wing with the lower portions of the macular band somewhat larger and less dentate. Underside. Both wings with less defined markings than in intermediate form. Female. Upper-side. Fore-wing with the band slightly broken at posterior end. Hind-wing with the lower portions of band somewhat wider. Underside with the markings indistinct.

The wingspan is 30–35 mm. Adults are on the wing year-round.[6]
