Volga Region

The casebearer`s fauna of the South-East of European Russia in its forest-steppe and steppe landscape zones on the territory of the Volga region in 1990–2016 was studied. The high species richness and the heterogeneity of the taxonomic structure of the casebearer moths on the border of forest and steppe cenoses on the border with the steppe were observed. It was established dwelling 172 species of casebearers of the 49 genera and their biotopical distribution in the studied landscapes.

In the article results of use of Malaise trap for the study of the beetles local fauna (Insecta: Coleoptera) in the territory of National Park «Khvalynsky» is given. Compiled a list of 95 species from 32 families Coleoptera. Antherophagus pallens (Linnaeus, 1758) and Saperda octopunctata (Scopoli, 1772) are recorded for Saratov region in first time.

In the flora of the Chuvash Republic, 40 species of the genus are revealed. 11 of these (A. altaica, А. argutiserrata, A. barbulata, A. cheirochlora, A. exilis, A. gibberulosa, A. hebescens, A. oxyodonta, A. plicata, A. sibirica, A. vorotnikovii) are registered in the Republic for the first time. Earlier, two species (A. pustynensis Czkalov and A. obtusa auct. non Buser) were noted here erroneously. Species are revealed whose richness corresponds to the level seen in neighbouring regions and approaches the maximum possible.
