The butterfly is locally common on the montane hill-top and occurs sympatrically with Horaga syrinx maenala in Yala. 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.
Photo record from Koh Samui has not been confirmed which subspecies. I regard it as this subspecies provisionally, However, confirmation with specimen is needed in future.
