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).
