The butterfly is locally not rare in montane forests at low to high elevations (Alt. 400 - 2000m) and is frequently found at forest edges.
Some examples from Laos show transition to ssp.margala. The relationship between the two subspecies is still not clear. Further taxonomic study is needed.
The markings of females are rather variable. Ek-Amnuay,[2007] described taxon sutthai from N.Thailand, however this name is unavailable and it is considered to be an extreme dry season form.
