The subspecies is not very constant and at the edge of its range merges into ssp. 

 sappho and ssp. astola ; this is to be expected in a secondary growth insect which, 

 throughout much of its range, has few natural barriers to its wandering (though not 

 strictly migrant) tendencies. Examples from Eastern China are typical. The 

 few examples from Korea in BMNH are similar. The two Korean males from which 

 Matsumura described curvata had an elongated streak beyond cell and a small 

 postdiscal spot in space 4 on the fore wing ; such examples occur frequently in 

 ssp. sappho, but very rarely in ssp. intermedia. Examples from Japan generally 

 resemble East Chinese examples, but there is a tendency for the hind wing postdiscal 

 band to be reduced and sullied, especially in Shikoku. A single female from Ishigaki 

 (Ryu Kyu Is.) shows only a slight approach to ssp. formosana. Examples from 

 Szechwan and N.W. Yunnan usually have smaller markings than Eastern Chinese 

 examples, and often closely resemble examples of ssp. astola from the Eastern 

 Himalayas and N. Burma. A pair labelled ' Fort Naryne ' (Eastern Turkestan) 

 do not differ from Szechwan examples.
