Leptidea amurensis

Leptidea amurensis is a butterfly of the family Pieridae. It is found from western Siberia to the Ussuri region and in North Korea, China, Mongolia and Japan.

Description in Seitz
amurensis L. amurensis Men. (27 g) from the Amur, North China and Japan, is especially characterised by the elongate forewing. The upperside is white, the male having a larger blackish subapical patch, which is absent from the female or is much smaller and less well marked; the underside is white, with a yellowish apical spot on the forewing and grey shadowv markings on the hindwing. — The spring-form vernalis Graes. is smaller, being darker beneath. — vibilia Janson[ now L. sinapis ssp. vibilia Janson, 1878], from North Japan, has more pointed wings than amurensis being similar to duponcheli in markings and colour. — morsei Fenton is apparently an aberration in which the subapical spot of the forewing above is less developed.

Biology
The larvae feed on Hedysarum ussuriense, Lupinus species and Vicia amoena.
