Notes
The butterfly is locally not rare in montane forest at low elevations (alt.150m - 450m).
Moore,1859, in describing this taxon, gave the type locality as "China", however Distant,1886 illustrated a female specimen and expressed doubts about the type locality. Afterwards, Fruhstorfer,1906, 1913 assumed it from Malaysia, and Corbet,1945 considered it as Perak, Malaysia which I also followed. I treat all populations from P.Thailand to Singapore as the same taxon temporarily, however further taxonomic study is needed.
