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
Three or four subspecies are described; Delias of the World (Pequin, 2021) is uncertain about the status of ssp. adelma. There is a form ssp boyalea in which the markings are not yellow coloured, but brick-red (Pequin, 2021).
