Notes

The butterfly is locally common in montane forests at low to moderate elevations (Alt. 50 - 1300m). Both sexes visit flowers and males frequently come to the banks of streams and puddles to suck water. Males are territorial on trees and often settle on the underside of leaves with their wings spread.
