Leptidea amurensis
Introduction '''''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''.
