This is a quite localized species, however it is not rare in its habitats. The butterfly is found in montane forests at moderate elevations (Alt. 500m). Males frequently come to the banks of streams and puddles to suck water.
The population from northern Thailand has rather large black spots and obscure submarginal markings on the UnF compared to other taxa. Further taxonomic and distributional studies are needed.
