The butterfly is uncommon in montane fields at high elevations (Alt. 2000 - 2200m).
Ek-Amnuay,[2007],2012 recorded it from Doi Pha Hom Pok, Chiang Mai, however it is an erroneous locality; Doi Lang, a mountain on the border between Thailand and Myanmar, is correct. A few records from the area are known until now, most likely a vagrant from Myanmar.
