Notes
The butterfly is locally common in montane forest at low to high elevations (alt.400m - 1700m).
Lang,2009 and Monastyrskii,2019 treated ssp.shan as synonym of nominotypical subspecies, however it is small in size, pure white markings on the upperside even in rainy season form. Thus I consider ssp.shan is a good subspecies. And I treat a taxon from N.Vietnam as this subspecies provisionally, however further taxonomic study is needed.
The relationship between orientalis is still unclear. Further study including DNA analysis is needed in the future.
