The butterfly is locally common in montane forest at moderate elevations (Alt.500m - 1000m) and frequently comes to rotten fruits that has fallen to the ground.
The records of Godfrey,1916,1930 from 'Prae [Phrae]' are doubtful. I have not seen any specimens from this area, therefore I have excluded it from the distribution map.
I treat the populations of Mae Hong Son and Phetchabun-Chaiyaphum as the same taxon. However, the distribution pattern is somewhat strange. It has isolated distribution in northwestern and central-northern part of the country. Further taxonomic and distributional studies are needed.
