The butterfly is common in secondary and montane forests at low to moderate elevations (Alt. 300 - 1000m). Both sexes visit flowers, and males occasionally come to the banks of streams and puddles to suck water.
The whitish discal spots on the UpF of females are highly variable and in some individuals are very small and indistinct.
Records from Phu Quoc and Cuc Phuong are doubtful. Further distribution research is needed.
