The butterfly is common in montane forest at low to high elevations (Alt.300m - 1600m) and is found around small stream.
Both ssp.dhyana and ssp.fabia occur together from central to north Thailand. It seems to be a transition zone of both subspecies. In some localities of Chiang Mai and Lampang, N.Thailand, ssp.fabia, ssp.dhyana and Pseudocoladenia fatua are found sympatrically. In addition, the species is found to occur sympatrically with Pseudocoladenia fatih festa in Nan, N.Thailand.
