The butterfly is locally common in montane forest at moderate to high elevations (Alt. 800 - 2000m). Males are territorial on trees at hilltops. In some places, it occurs sympatrically with Pratapa icetoides.
The records of Pratapa contractus by Nakamura et al.,2010 and Nakamura & Wakahara,2012 from Laos are considered to be this species.
