The butterfly is locally common in montane forests at low to moderate elevations (250–550 m a.s.l.). Both sexes visit flowers. Males are frequently observed mud-puddling along stream banks and at puddles. Males are territorial on trees and often settle on the underside of leaves with their wings spread.
