The butterfly is uncommon in montane forests at low to moderate elevations (Alt. 450 - 600m). Males frequently come to the banks of streams and puddles to suck water.
This species can only be distinguished from Coladenia tanya by examination of the male genitalia.
In Ranong Province, P. Thailand, both the nominotypical subspecies and ssp.sundae have been confirmed. de Jong & Treadaway (1992) recorded ssp.agni in Chanthaburi, S.E. Thailand. However, in our survey, only ssp.sundae has been found in the area so far, suggesting that this may be a misidentification. Further taxonomic and distributional studies are needed.
