Notes

The butterfly is locally not rare in montane semi-dried forest at moderate elevations (alt.700m - 1000m) and is found in darker places than other species.
This species is characterized by a darker ground color on the upper side of both wings than Ypthima similis, however both species are quite similar, and identification requires examination of the male genitalia.
