The butterfly is common in montane and secondary forests at low to moderate elevations (Alt.30 - 1200m). 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 dhyana and Pseudocoladenia fabia occur together from central to northern Thailand. In some localities of Chiang Mai and Lampang, N.Thailand, dhyana, Pseudocoladenia fabia and Pseudocoladenia fatua are found sympatrically.
