Insects, as the most diverse group of invertebrates, are often unfairly underrepresented in Red Lists of threatened taxa. Despite the significant biodiversity and ecosystem functionality of this group, regional Red lists of taxa often ignore truly threatened species and, conversely, include species that are quite common in adjacent regions. The paper presents the results of long-term monitoring of rare insect species in 14 regions of European Russia (Vladimir Region, Volgograd Region, Voronezh Region, Lipetsk Region, Moscow Region, Nizhny Novgorod Region, Penza Region, Ryazan Region, Republic of Mordovia, Republic of Tatarstan, Samara Region, Saratov Region, Tambov Region, Ulyanovsk Region). The aim of the study was to summarise the results of long-term research of rare species listed in regional Red Data Books and the Red Data Book of the Russian Federation. A wide variety of insect collection and census methods were used. To characterise regional Red Data Books during the research, the taxonomic lists, which were actual at the time of the research, were used. The information resulted in 96 insect species from eight orders (one from Odonata, three from Orthoptera, seven from Hemiptera, 64 from Coleoptera, two from Neuroptera, one from Raphidioptera, 13 from Lepidoptera, 5 from Hymenoptera), included in the Red Data Books of the studied regions; of these, 18 species are also included or were included in the recent (2021) or previous (2001) edition of the Red Data Book of the Russian Federation, respectively. Between one and three species listed in the Red Data Book of the Russian Federation were recorded for the first time in seven regions. The number of species included in the regional Red Data Books ranges from 47 species in the Volgograd Region to 261 species in the Voronezh Region. It is assumed that 30 species from the studied taxa do not require special protection measures and should be excluded from protected lists of regional Red Data Books. Justification for such recommendations is provided in each specific case. Leptura aurulenta is proposed to be included on the list of the Red Data Book of the Russian Federation.
