Notes
The species is highly variable even in the same locality and individual variation seems to be more pronounced than geographic variation. I consider ssp.thalimar from Malay Peninsula is hardly separable from ssp.ethion. Therefore I treat it as a synonym of nominotypical subspecies. Individuals in dry season tend have wider white band on the upperside.
The butterfly is not rare in montane forest at low to moderate elevations (alt.100m - 700m) and is often found along forest paths or forest edges.
