The butterfly is common in montane semi-dried forests at low to moderate elevations (Alt. 100 - 1100m). Males are territorial on shrubs or trees. This species is sympatric with A.abnormis, A.echerius and A.latifasciata, depending on its habitat.
The individuals and seasonal variation are very conspicuous. We consider ssp.angustilineata from S.Vietnam is a synonym of ssp.angulata.
