Diagnosis
The distal margins of the forewings are straighter than in other species, and the hindwing discal spot is more regular, square or rhomboidal rather than shaped like an ‘N’ or ‘M’. The postmedials have large, almost entirely white elements, but these are present only in the places described for laesaria.
Geographical range
Korea and adjacent parts of Siberia, Japan, N.E. Himalaya, S. China; Borneo, Sumatra (ssp. vapida).
Habitat preference
The species was common from 1200m to 1930m on G. Kinabalu, and two specimens were taken at 1200m on the limestone G. Api, all in upper montane forest.
Biology
The larva in Japan was illustrated by Sugi (1987). It is relatively robust, tapering from the prolegs anteriorly, and is leaf-green in colour.
The host-plants in Japan are Malus (Rosaceae), Eurya (Theaceae) and Viburnum (Caprifoliaceae).
