The butterfly is locally common in montane forests at low to moderate elevations (Alt. 400 - 1300m) and is occasionally found at hilltops. Males are territorial on trees.
As Takanami,1991 pointed out, Deudorix diara and Deudorix epijarbas have the same genitalia and diara is considered to be a form of epijarbas.
