Notes

The butterfly is locally not rare in montane forests at low to moderate elevations (Alt. 300 - 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.
