The butterfly is locally common in montane forest at low to moderate elevations (Alt.450m - 600m).
Inoué & Kawazoé,1965b recorded ssp.bornea from S.Vietnam, and the illustrated genitalia is consistent with this. Pinratana,1985 recorded ssp.minuscula at Ranong, P.Thailand, but this is uncertain. Male genitalia must be examined for reliable identification. Further taxonomic study is needed.
