The butterfly is locally not rare in montane forests at low to moderate elevations (Alt. 450 - 1000m). Males occasionally come to the banks of streams and puddles to suck water.
The records from Chonburi and Bangkok by Godfrey (1930) are somewhat doubtful. These are on hold until a reliable specimen is confirmed.
