The butterfly is locally very common in primary forests, especially mixed with bamboo, at moderate elevations (600–900 m a.s.l.). Both sexes come to rotten fruits that has fallen to the ground or tree sap. Males are occasionally observed mud-puddling along stream banks and at puddles.
Ek-Amnuay ([2007], 2012) recorded from 'Omkoi, Chiang Mai', but I have never seen any specimens from there. Thus It is considered an incorrect locality.
