A very common species that is distributed throughout the whole region. It is instantly recognisable because of the row of white rings or 'studs' across the hindwings. This separates it from all the look-alike members of the Athyma genus and the smaller sized Neptis. There is no visual difference between the sexes and the only way of separating them in the field is that the females usually hang around the host plants while the males are usually found puddling. However, this is not a definitive rule and cannot be relied on.
It is a fast flier and usually found in the vicinity of streams. Males exhibit terrirorial behaviour, chasing off any butterflies that intrude on their territory. The species flies all year round and is multivoltine with several broods per annum.
NOTE: There is a difference of opinion as to which genus this butterfly belongs. Some place it in the Athyma genus and others in the Limenitis. Until there is a consensus this sheet has been created under both genera.

Life History: egg 4 days instar 1 3 days instar 2 2-3 days instar 3 2-3 days instar 4 4 days instar 5 6-7 days pupa 8-9 days Total egg to adult 30-33 days. All times are approximate.
Larval Hosts: Ixora congesta, Diospyros lanceifolia (Ebenaceae), Ilex asprella, Ilex cymosa, Ilex micrococca (Aquifoliaceae), Aidia canthioides, Pitardella sikkimensis (Rubiaceae). Actual host plant used depends upon location and availabilty of plant species.
