ANALYSIS OF THE DISTRIBUTION AND STRUCTURE OF DIURNAL LEPIDOPTERA (LEPIDOPTERA: HESPERIOIDEA, PAPILIONOIDEA) RANGES IN UDMURTIA

Abstract

The article analyzes the zonal landscape distribution and the structure of the diurnal lepidoptera ranges on the territory of the Udmurt Republic. The zonal indicators of the dynamics of the species richness of lepidoptera in the region have the following form: the southern taiga - 100 species, the subtaiga as a whole-122 species, including the northern band of the subtaiga-107 species, the southern band of the subtaiga-119 species. The zonal trend is based on the significant participation of the regional fauna of the regional representatives. The general indicators of the numerical participation of structural and arealographic groups in the fauna are as follows: 46 species are located within the generalized part of the area in the region; 22 species are located near the periphery of the area; 42 species are located on the border of the area; 13 species are located on the periphery of the area. The main share of lepidoptera located in the marginal parts of their ranges is made up of southern subboreal (steppe and non-morale) and subboreal-subtropical representatives (72 species). The proportion of such species among the northern geographical groups - the Hypo-Arctic and boreal (16 species) is significantly lower. The most important biochorological units that determine the conditions for the distribution and localization of bulavous are uplands, forest landscapes on the sands, as well as the valleys of large and medium-sized rivers in the southern part of the region.
