The butterfly is common in montane forests at low to high elevations (Alt. 300 - 1600m) and is found around small streams. Both sexes visit flowers and males frequently come to the banks of streams and puddles to suck water. They often rest on the underside of leaves with their wings spread.
Both ssp.dhyana and ssp.fabia occur together from central to northern Thailand. In some localities of Chiang Mai and Lampang, N.Thailand, fabia, Pseudocoladenia eacus dhyana and Pseudocoladenia festa or Pseudocoladenia fatua are found sympatrically. In addition, the species also occurs sympatrically with Pseudocoladenia fatih in Nan, N.Thailand.
