The butterfly is very common in montane forest especially bamboo forests at low to moderate elevations (Alt. 300 - 1200m).
According to Pinratana,1983, Okamoto et al.,2013 and Kimura et al.,2016, both ssp.zal and ssp.despoliata occur sympatrically from Kanchanaburi, W.Thailand to Prachuap Khiri Khan, northern part of P.Thailand. It seems a transition zone of both subspecies.
