Volume 14 in this series is dedicated to butterflies of the Russian Far East (Khabarovskiy and Primorskiy Kray, Jewish Autonomous and Amur Regions), and the Sakhalin and Kuril Islands. Unlike the thirteenth volume, Butterflies of Afghanistan, the territory of the Far East has a long history of study and is quite well known, especially in the southern parts. Here are typical representatives of both the Chinese and Japanese fauna, and the northern parts of Asia, including the arctic species. Such diversity was the reason for numerous expeditions, research in the Far East, as well as a large number of publications. This book differs from all previously published ones not only by its rich illustrative material but also by the fact that during the preparation all historical collections and almost all type material were investigated, and all original descriptions and available literary sources were studied. The distribution of species based on point maps is published for the first time. This book covers 308 species of Rhopalocera belonging to 5 families.
