Occurrence of butterflies and moths (Insecta, Lepidoptera) in Mordovia State Nature Reserve.

BACKGROUND: Faunistic research in protected areas is of greatest interest since these are the most unique places in the region. Many of these are islands of minimal anthropogenic impact, such as the Mordovia State Nature Reserve (Russian Federation), founded in 1936. The purpose of the publication of the basis of faunistic research - occurrences of species, is availability of factual information to a broad range of researchers and its implication in research on a wider scale. NEW INFORMATION: For the first time, a total of 7,606 records of Lepidoptera occurrences from the Mordovia State Nature Reserve with coordinates have been published as a dataset. It is necessary to embed them in the Global Biodiversity Information Facility (GBIF) in order to make them accessible to everyone. As a result of research from 2007 to 2021, more than 600 taxa were identified for the first time for the territory of Mordovia State Nature Reserve, including more than 450 species for the Republic of Mordovia, four species for the Middle Volga Region and eight species for the Middle and Lower Volga Region.

Present day bio-invasions in the Volga-Ural Region: from the South to the North or from the East to the West? Cameraria ohridella (Lepidoptera: Gracillariidae) in the Lower and Middle Volga.

The occurrence of the invasive horse-chestnut leaf miner, Cameraria ohridella, in the cities of Saratov and Samara in the Volga Region was recorded for the first time in 2018. Possible pathways of species penetration from the southern parts of European Russia are discussed.
