The butterfly is locally not rare in montane forests at low to moderate elevations (Alt. 30 - 700m). They often fly out from bushes along the trail and rest on the underside of leaves.
According to the records of Tsukiyama,1992, Chiba,2009 and Kimura et al.,2011, both ssp.stigmatus and ssp.caudatus were found sympatrically in Chiang Mai province, N.Thailand. Further taxonomic and distributional studies, including DNA analysis, are needed.
