The butterfly is locally common in forests at moderate elevations (500–1,000 m a.s.l.) 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.
