“Off the recorded Appias
species, 10 species occurs in Indian Subcontinent i.e. albina, libythea,
paulina, lyncida, nero, indra, melania, lalage, wardii and olferna. Apart
from A.nero i.e bright orange coloured, all the Appias species found in India
are white on the upper wing surface, with the apex and outer margins of the
forewings marked to a greater or lesser extent with black, according to
species. Females of the "white" species have a dull brownish-white
ground colour, heavily suffused with dark brown around the margins and in the
fw discal cell. The undersides vary considerably - e.g. albina is pure white;
indra is greyish, heavily mottled with brown; and the underside hindwings of
lyncida are bright yellow with broad chocolate margins”. (learnaboutbutterflies.com)
