Notes

The butterfly is uncommon in montane forests at low elevations (Alt.50m - 450m).
This species can only be distinguished by examination of the male genitalia. Ek-Amnuay ([2007],2012) recorded Caltoris confusa from Thailand, however, it is considered to be this taxon. Further distributional research is needed.
