Notes

The butterfly is locally not rare in montane forests at moderate to high elevations (Alt. 900 - 1700m). Both sexes visit flowers. They often fly out from bushes along the trail and rest on the underside of leaves with their wings spread.
The male genitalia is slightly different from Celaenorrhinus dhanada, and this species is sympatric with Celaenorrhinus dhanada in some parts of Chiang Mai province, N.Thailand. Therefore, I treat it as a distinct species.
