The butterfly is common in semi-dried forests at low to moderate elevations (Alt. 30 - 1300m). Males are territorial on trees or shrubs and occasionally come to the banks of streams and puddles to suck water. Very rarely, males with orange patch on the UpF may appear.
Saito & Seki (2003) treated phama as a synonym of hewitsoni. However, the population from Omkoi, Chiang Mai seems to be different from tavoyana. In this area, the female like tavoyana was not been found. And females similar to Omkoi have not been found in other areas of Thailand. This is considered to be ssp.geta. However, in Lak Sao, Laos, both tavoyana and geta-like individuals occur together. The relationship between these will require further taxonomic review in the future.
