Long-Term Changes in the Fauna of Diurnal Lepidopterans (Lepidoptera,Diurna) in the Northern Taiga Subzone of the Western Russian Plain

In the diurnal lepidopteran fauna of the northern taiga subzone in the western Russian Plain, the species inhabiting primary biotopic complexes typical of this subzone currently account for slightly more than 60% of the total species richness and abundance. A large part of the fauna is represented by the species of more southern origin, whose expansion to the northern taiga was caused by anthropogenic transformation of landscapes between the 12th and 20th centuries and recent climate warming.
