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 in Seki et al. (1991) pointed out, Deudorix diara and Deudorix epijarbas have the same genitalia and diara is considered to be a form of epijarbas.
