The butterfly is locally not rare in montane forest at moderate elevation (alt.700m - 1300m) and is occasionally found on the hilltops.
The individuals that having dark markings in space 4 and 5 on the UnH occur frequently. The ordinary form is indistinguishable from allied species by underside markings. The color on the upperside or the male genitalia need to be examined.
