Notes
The butterfly is locally not rare in montane forest at moderate to high elevations (alt.1000m - 1600m) and is frequently found on the hilltops. Male makes a territory on the trees.
Very similar to Prosotas nora and almost indistinguishable from the underside. The color and markings on the upperside or the male genitalia need to be examined.
