The butterfly is very common in montane forests at low to high elevations (Alt. 20 - 1800m).
Both male and female are polymorphic and very variable. The populations in the continental Indo-china region are highly variable and individual and seasonal variation seems to be more pronounced than geographic variation. I tentatively treat all populations to this taxon, further taxonomic study is needed. Some specimens from Tak province, W. Thailand are very similar to ssp.crepax, and the area seems to be a transition zone.
