The butterfly is locally common in montane forests at moderate elevations (Alt. 20 - 700m). Males are territorial on trees at hilltops and occur sympatrically with Horaga onyx sardonyx. Time of male activity is different between the two species. In syrinx from about 11:00 to 14:30 while in onyx from about 15:00 to 16:00.
Cowan,1966 treated the record from Ranong by Godfrey,1930 as ssp.moulmeina. However, the possibility of ssp.maenala is also considered and needs to be confirmed by reliable specimens.
