Notes

The butterfly is locally not rare in montane forests at low to moderate elevations (Alt. 50 - 800m) and is crepuscular. Males frequently come to the banks of streams and puddles to suck water.
The area from the northern part of peninsular Thailand to central Vietnam seems to be a transition zone between ssp.sena and ssp.uniformis. Both taxa are sympatric, and intermediate individuals are often found together.
