The sexes are similar, but the white sub-apical marking on the upper side 

 of the forewing is larger in the female, than in the male." (Kershaw.) 

 "Common all over Japan and Korea. It is a variable species in the 

 contour of the wings, width of the blue submarginal bands, and the size 

 and colour of the costal spots, which may be either blue (canace), or white 

 (glauconia), the blue submarginal band of the forewing, which usually 

 ceases at its junction with the larger costal spot, is in some specimens 

 carried up as far as the apical spot, noticeably so in specimens taken in 

 the mountain districts of central Japan in October. * * * So far as 

 I know the var. glauconia appears to be confined to Japan and the Loochoo 

 Islands. * * *." (Leech.) 



The adult is very partial to the gummy exudations of wild 

 cherry and other trees and to the sap issuing from Cossus bur- 

 rows in oak trees. As Kershaw observes, it is occasionally very 

 bold. Individuals of this species have settled on my butterfly 

 net while I held it and on my white helmet. It is fond of sitting 

 on wet places on the roads and of flying about late in the after- 

 noon just before dusk, when it is more than usually audacious. 



Matsumura records Vanessa glauconia Motsch. (= no-japonica 

 Sieb.) from the Japanese islands of Hokkaido (Yezo) , Honshu, 

 Shikoku, and Kyushu, and I have taken it in Honshu and Kyushu 

 in various localities on the mountains and plains from May to 

 October. It undoubtedly hibernates in the imago state, as I have 

 taken specimens flying in the months of March and April at 

 Tokyo. I have observed it in Japan as high as from 1,300 to 

 1,700 meters (4,000 to 5,000 feet) . There are probably two if 

 not three broods in the year according to its geographical range. 

 In Hokkaido there is probably only one brood, as the summer is 

 very short.
