The butterfly is locally common in montane dense forest mixed with bamboo at moderate elevations (alt.300m - 600m) and often comes to rotten fruits that has fallen to the ground. It occurs with S. cambodia, however the species prefer to higher elevations.
For a long time, ssp.siamensis was thought to be S.E.Thailand population. However, an examination of the type specimen in the NHML, I realized that the spear-shaped black markings on the UpF is not as well developed as in the S.E.Thailand population, and that the N.Thailand population corresponds to this taxon because of its shape. Thus I treat ssp.siamensis as taxon of N.Thailand. And taxon from S.E.Thailand is unnamed provisionally.
