Subboreal geographical elements of the macrolepidoptera fauna of the European northeast of Russia

Based on the material of Macrolepidoptera, high percentage of in the taiga and tundra biota of subboreal geographical elements - one of the main biogeographic features of the European North-East of Russia - is considered. It is shown that over 50 species of Lepidoptera from 11 families have peripheral area covers in various extent taiga zone and the southern parts of Hypoarctic zone, and the area of their ecological optimum situated in the subboreal forest and steppe zones. In consideration of peculiarities of the natural process, the analysis of the landscape-zonal distribution of Lepidoptera species suggests that the penetration of subboreal species was began and gradually took place during the warm periods of Holocene. A few groups of Holocene climatic relicts have been preserved in various areas of the taiga and the forest-tundra zones. At the present time the most of subboreal species of Lepidoptera in the European NorthEast of Russia are new and actively distributing in anthropogenic habitats.
