The butterfly is locally common in forests at moderate to high elevations (700–1,600 m a.s.l.). Males are territorial on undergrowth at forest edges.
This species has both individual and seasonal variations, and females in particular are very variable.

Ek-Amnuay ([2007]) described a new ssp.sukhumalindi from Koh Chang, Trat ; Koh Tarutao, Satun and Than To, Yala from specimens in P. Sukkit collection, however this is an unavailable name. Moreover I examined all specimens in the Sukkit collection and no specimen had identical location and date as the original description. All drumila specimens came from North Thailand (Mae Hong Son; Chiang Mai; Nan). Therefore I compared them with illustrated specimens in Ek-Amnuay ([2007], 2012) and a male and a female specimen matched them. The data is mentioned above. I consider the data in the original description is incorrect.
