| Summary: | Grass meadows are one of the main habitats of Lepidoptera in the taiga zone of the northeast of the Russian Plain. These plant communities are a convenient platform for the observation of Rhopalocera long-term population dynamics and species diversity. The article presents results of the study of long-term dynamics of the Lepidoptera population structure and species diversity in two grass meadows in the neighborhood of Ukhta city, Komi Republic. 47 species from six fami-lies were registered. During the 13-year observation period we did not notice any significant changes in the Rhopalocera population structure in the floodplain meadow. The Lepidoptera spe-cies group of the grass meadow formed on the site of forest felling was transformed towards de-pletion and decomposition during the spruce forest self-restoration. Succession changes in plant communities lead to the transformation of topical Rhopalocera groups, both towards increasing the species diversity and towards their degradation and complete decomposition. As a whole, the researches carried out confirm the conclusion about the stability of the structure of the population of Lepidoptera in conditions of preservation of the composition and structure of phytocenoses for a long time period. Within the boundaries of one particular fauna in similar plant communities, including secondary origin, a similar population of Lepidoptera is formed. This causes the possibility of typological descriptions and extrapolations in characterizing the spatio-temporal organization of the population of Rhopalocera and provides the basis for the development of a syntaxonomical direction in lepidopterology. |
