[Butterflies (Lepidoptera, Diurna) in boreal forests of southeastern Russia: 1. Light coniferous forests].

Species groups formed in light coniferous forests prevailing in southeastern Russia are considered using the example of butterflies. Problems concerning the formation of species composition and its originality in some insects groups are discussed. A classification analysis of species checklists for twelve local faunas of Transbaikalia and the southern Russian Far East is performed. It is shown that the faunas of areas occupied by light coniferous forests have a common background.
