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.
