The butterfly is locally not rare in montane forests at low elevations (Alt. 30 - 400m).
Previously, the populations of SE. Thailand and Cambodia were treated as ssp.spenda. However, there are no differences between these and ssp.distanti. I therefore treat these populations as the nominotypical subspecies as well.
