The butterfly is rare in lowland forests (150 - 350 m a.s.l.).
The populations from S.E. Thailand to Cambodia seem to be a distinct subspecies of falcipennis or a separate species. Ek-Amnuay ([2007], 2012) recorded it from 'Ranong', but the locality is rather doubtful. Further taxonomic and distributional studies are needed.
