MORPHOLOGY
External characteristics
Male
Female
The females generally have a different underside wing surface than the males, by being darker with broader margins on both wings (D'Abrera, 1982).
Subspecies and variation
Two subspecies are described. Ssp. homeyo has a more cream or pale yellow colouration on the hindwing underside, instead of the vivid yellow colouration (Pequin, 2021).
