The butterfly is rare in montane forests at low elevations (Alt. 30 - 150m).
There is a tendency for the male red patch on the UpF to get smaller and smaller from north to south. The record from Phang Nga by Küppers & Janikorn,2020 identified as Drupadia rufotaenia rufotaenia is possibly this taxon based on their description. However, this cannot be confirmed due to the lack of specimens or photos. Further taxonomic and distributional studies are needed.
