The nature conservation depends on the completeness of the knowledge about the biodiversity in the study area. Today, data on distribution and diversity of Diptera taxa remain fragmentary. This paper supplements data on the diversity of Diptera species in Europe, Russia, and the Republic of Mordovia. We have studied 1321 specimens of 241 species collected in 2013–2022. Among them, there are species, which are new for Russia (Neoempheria brevilineata, Desmometopa discipalpis) and for both Russia and Europe (Neophyllomyza flavescensis, Phyllomyza auriculatusa, P. luteipalpis, P. orbita, P. piceus, P. striolatum). We have found for the first time 231 Diptera species for the fauna of the Republic of Mordovia; the families of Bolitophilidae, Keroplatidae, Scatopsidae, Platypezidae, Micropezidae, Opomyzidae, Asteiidae, and Milichiidae have been found for the first time in this region. Anthrax incomptus (Bombyliidae), being previously reported for the Republic of Mordovia, has been excluded now from the fauna of this region. Nine Diptera species have been previously indicated for the Republic of Mordovia without reliable confirmation by collected specimens. In this study, we have confirmed their presence in the Republic of Mordovia. Taking into account the results of the present paper, the Diptera fauna of the Republic of Mordovia includes currently 1187 species belonging to 71 families. Data on collecting methods have been presented for the found species. We provide a comparison of collecting methods and suggestions for an effective inventory of the regional Diptera fauna. We are of the view that the number of the used collecting methods affects positively the results of the fauna inventory.

The suborder Heteroptera (order Hemiptera) is one of the most interesting groups of Rynchota. It is found in various ecosystems around the world and belongs to predators, parasitous (in particu-lar hematophagous), mycetophagous and herbivorous types. Species with mixed nutrition are common. The study is aimed to describe the fauna and distribution of hemipteran insect species in the Republic of Mordovia (the central part of the European part of Russia). The study was conducted from 2004 to 2022. Specimens were collected using traditional hemipteran insect col-lecting methods (manual collecting, light trap, entomological net, Malaise trap, Merike plates, window and soil traps). We examined 4895 specimens of Hemiptera. Species diversity of Heter-optera (order Hemiptera) of Republic of Mordovia accounts for 363 species from 34 families. Of these, 15 species (Campylosteira verna, Allorhinocoris flavus, Grypocoris sexguttatus, Acetropis gimmerthalii, Geocoris grylloides, Platyplax salviae, Emblethis ciliatus, Aellopus atratus, Rhy-parochromus quadratus, Parapiesma quadratum, Berytinus montivagus, Pyrrhocoris margina-tus, Enoplops scapha, Dybowskyia reticulata, Ventocoris halophilus) are listed for the region for the first time. Twenty-three species (Agramma femorale, Adomerus biguttatus, Aelia acuminata, Carpocoris fuscispinus, Coreus marginatus, Dolycoris baccarum, Eurydema oleracea, Gerris lacustris, Graphosoma lineatum, Kleidocerys resedae, Labops sahlbergii, Lopus decolor, Lygus pratensis, Nithecus jacobaeae, Palomena prasina, Polymerus unifasciatus, Prostemma aene-icolle, Pyrrhocoris apterus, Rhyparochromus pini, Stenodema calcarata, Cymus glandicolor, Eremocoris plebejus, Aphanus rolandri) constitute the main population of the Heteroptera fauna given in the dataset. The species diversity of Heteroptera of the Republic of Mordovia is roughly similar in number of species to that of neighbouring regions.

The article presents an analysis of the results of using a large number of pitfall trap lines to record the species composition of the two largest groups of phytophagous beetles (Coleoptera: Chrysomelidae and Curculionoidea) on the example of the territory of one region of the European part of Russia (the Republic of Mordovia). A series of collections were conducted between April and October 2022-2023, encompassing a diverse array of habitats (forest, steppe, near-water, wasteland) across various parts of the region. A total of 126 species from four families (approximately 18% of the fauna of the Republic of Mordovia) were recorded. These included 84 species of Curculionidae (22.9% of species), 42 species of Chrysomelidae (22.9%), 3 species of Brentidae, and 1 species of Anthribidae. Fourteen species are presented for the first time in the regional fauna. The collections are dominated by species whose adults are actively moving on soil or litter, particularly those belonging to the Alticini (Chrysomelidae) (33 species; 38.4% of the fauna composition) and the subfamily Entiminae (Curculionidae) (32 species; 45.1%). The collections represent a wide range of landscape-biotopic groups (meadow, ruderal, forest, near-water, and steppe species). Extensive materials obtained in pine forests and their pyrogenic successions in the Mordovia State Nature Reserve were also analyzed. The maximum species richness (30 species) was observed on fresh pyrogenic wastelands (1–2 years after fires). This is due to the association of many species of leafhoppers and weevils with habitats with sparse ruderal vegetation and coenophobic plants. A minimum of 10 species was observed on plots of old burned areas (13 years) where the primary vegetation is degraded and a full-fledged pine forest complex has not yet formed. The maximum abundance of two ecologically plastic species (Strophosoma capitatum and Hylobius abietis) associated with young undergrowth of pine and deciduous trees was recorded in this area.

Natural forests (closed habitats) and meadows (open habitats) are essential for the conservation of terrestrial biodiversity. Pubescent biotopes are of considerable importance as well. It is crucial to obtain data on the spatial distribution of Coleoptera in such biotopes because it helps protect natu-ral biotopes. The research was conducted in 2020 on the territory of the Republic of Mordovia (the center of the European part of Russia). Beer traps (with beer bait) were used to collect Coleoptera. The collections were carried out from April to October in various forests and open biotopes. To clarify the spatial distribution of Coleoptera, various forest interiors (meadow, edges, in the depths of the forest) were studied at two experimental sites. A total of 7771 Coleoptera specimens were recorded. In the open biotopes, the smallest numerical abundance of Coleoptera was obtained with relatively high species richness. The lowest species richness was obtained in the depths of the for-est at a height of 7.5 m. The edges of forests at a height of 1.5 m differed in the maximum species richness and number. At a height of 7.5 m, the number of Coleoptera was the greatest, but the spe-cies diversity was very low. The number of saproxious species was higher in forest biotopes. The number of anthophilic species was higher in the traps installed at the bottom. Differences in the number of species and individuals on different edges (northern, eastern, and western) were also determined. Thus, on the eastern and northern edges, in contrast to the western edge, the numerical abundance at the top was higher than at the bottom.

Forest fires are one of the main environmental factors that change the habitat and initiate the change of new forest communities. Burned areas are habitats representing a wide range of eco-logical niches, which can be used by many species of insects. It is especially interesting to ob-serve the restoration processes in the burned areas in the first years after the fires. In 2021-2022, on the territory of Mordovia State Nature Reserve, studies were conducted on the plots that had been burned in 2010 and 2021. Traps with bait based on beer and sugar were used for the study. Our results indicate that the largest number of flying insect forms in the first year after the fire was higher in unburned areas, and the parts of burnt areas located in the depths of the burned territory had the smallest number. The number of beetles was greatest in areas which were not affected by fire. Lepidoptera immediately returned to the site of the fire in 2021. Already the next year their number became much higher. There was no clear depend-ence on Hymenoptera. The number of Neuroptera and Blattodea was higher in the burned are-as of 2010. The seasonal dynamics of Coleoptera in the hot springs was one-peak, whereas in unburned areas it is usually two-peak.

In this paper, we present the results of our study on the seasonal dynamics and altitudinal distribu-tion of Vespidae in forest ecosystems of central European Russia. To conduct this study, we utilized beer traps. Our findings include the recording of 32 species from 4 families of Hymenoptera. The most numerous family was Vespidae. The dominant species from this order were Vespula vulgaris, Vespa crabro, Dolichovespula media, and Vespula germanica. The occurrence of these species was quite high, including species from the Crabronidae, Chrysididae, and Pompilidae families. These species are known to frequently visit flowers of various plants and feed on nectar and pollen. In five different biotopes, the highest number of Vespidae was found in oak forests, while the lowest num-ber was observed in pine forests. Vespula vulgaris was the dominant species in birch and oak for-ests, while Vespa crabro was more prevalent in pine and linden forests. The seasonal dynamics of the number showed a large peak in early July, likely due to a significant increase in air temperature during the day and night. This peak may have been caused by a large number of new-generation workers leaving the nests at this time. Additionally, the number of Vespidae in traps located in the undergrowth was slightly higher than those in traps in the canopy.

In forest ecosystems, fires profoundly impact the habitat and seasonal dynamics of numerous Coleoptera species. The phenology of species and communities is particularly noteworthy in burned areas that were previously forest ecosystems. In 2023, research was conducted in the Mordovia State Nature Reserve on 11 burned plots in 2021 and control plots. The research employed the use of beer traps, which are baited with a combination of beer and sugar. In the second year after the fires, species from the families Nitidulidae, Cerambycidae, Scarabaeidae, and Elateridae exhibited the highest total number across all plots, accounting for 84.8% of all Coleoptera specimens collected. A single peak in the abundance of Coleoptera was observed on all plots during the month of May. The second peak in abundance during the autumn season was relatively modest in scale and was observed exclusively on unburned 2021 plots. Nitiduli-dae beetles appear in traps earlier than other beetles, with their number peaking in April and May. Thereafter, their number declined in June. The number of Cerambycidae and Scarabae-idae on all plots was relatively low in April but increased significantly in May and June. The peak abundance of Elateridae was observed in June, although the first individuals were rec-orded in April. A precipitous decline in the abundance of the species was observed in July, with only a single specimen being recorded in August. The Elateridae were observed to be particularly prevalent in burned areas where deadwood was present. There are variations in the observed differences between individual families, which are related to the location of plots, the condition of the vegetation cover, and the presence of flowering plants, deadwood, and dry trees on the plots.

Studies were conducted in the temperate forests of the European part of Russia (territory of the Republic of Mordovia). Beer traps with bait made of beer and sugar were used for the studies. Three plots were selected for the study, which differed in the composition of plants at the edges, adjacent open ecosystems and types of forest ecosystems. The forest was adjacent to this open ecosystem and there was no transition zone of shrubs. Eight traps were used in each plot (1,2 - edge-below, 3,4 - edge-above, 5,6 - forest interior-below, 7,8 - forest interior-above). They were located 1.5 m (further named as “below” traps) and 7.5 m (further named as “above” traps) from the ground level. During the experiments, 52306 specimens from 28 families of Diptera were captured. In terms of total abundance, representatives of 25 families were present in the lower traps and species from 27 families were present in the upper traps. The general pattern was the highest abundance of Diptera at the edges in all plots. Nine fam-ilies (Tipulidae, Anisopodidae, Lonchaeidae, Milichiidae, Drosophilidae, Anthomyiidae, Fanniidae, Muscidae, Calliphoridae) accounted for 93.3% of all Diptera abundance in all plots. The families Tipulidae, and Drosophilidae were the most abundant in lower traps within forest ecosystems. The families Lonchaeidae, Milichiidae, Anthomyiidae, Fanniidae, and Muscidae were most abundant in upper traps at the edges of forests. The families Anisopodi-dae, Calliphoridae were the most abundant in the lower down edges.

About 29,000 individuals are identified to the species level. In total, 342 species were recorded for both PAs. The greatest species diversity was recorded in the families Linyphiidae (109 species; 32%), Lycosidae (38 species; 11%) Gnaphosidae (28 species; 8%), Araneidae (25 species; 7%), Salticidae (24 species; 7%), Thomisidae (23 species; 7%) and Theridiidae (22 species; 6% from total species diversity). The five species most abundant in the lower stratum (litter and moss layer) of biocenoses were Diplocephalus picinus, Microneta viaria, Tenuiphantes tenebricola, Diplostyla concolor and Abacoproeces saltuum and the five species most abundant in the vegetative stratum (herb, shrub and tree stems and canopy) were Linyphia triangularis, Enoplognatha ovata, Evarcha falcata, Misumena vatia and Evarcha arcuata. The dataset contains information on the occurrence of seven rare species (Centromerus nurgush, Centromerus persimilis, Diplocephalus dentatus, Entelecara flavipes, Metapanamomops kaestneri, Pelecopsis radicicola and Porrhomma microcavense), three species (Agalenatea redii, Neoscona adianta, Thanatus oblongiusculus) that entered here from the steppe zone and two synanthropic species (Steatoda castanea, Tegenaria domestica).

Temperate forests are highly complex ecosystems in which many aspects of invertebrate distribution and abundance remain poorly understood. In order to accumulate data on the vertical and temporal distribution of forest Lepidoptera in the Republic of Mordovia (central European part of Russia), specimens were collected with beer-baited traps from April to October in 2019–2022. Traps were deployed at different heights above ground level (i.e., 1.5, 3.5, 7, and 12 m) in deciduous forests, pine forests, forest edges, and forest glades. Over the four-year sampling period, over 69,000 specimens of Lepidoptera were collected and examined. In deciduous forests, maximum abundance was observed at 12 m above ground level, whereas in pine forests, maximum abundance was observed at 7 m. In both forest types, the lowest abundance was observed at the lowest sample sites (i.e., 1.5 m above ground level). In forest glades in 2020, maximum abundance was observed at 2 m, with abundance showing a conspicuous decline with trap height above the ground. However, this pattern was not repeated in subsequent years. Lepidoptera exhibited various patterns of seasonal abundance among habitat types, but most showed bi- or trimodal patterns (corresponding with spring summer and fall), with the greatest number of specimens captured in late summer or autumn. Forest edges showed the greatest abundance of all sampled habitat types.

The possibilities of using beer traps for the study of Coleoptera fauna in various open biotopes were studied. The biodiversity of beetles was 208 species from 35 families. The largest number of species belonged to the families Cerambycidae (35 species), Curculionidae (26 species), and Elateridae (25 species). Only 13 species were found to be common to all habitats. Some patterns of species distribution in biotopes were revealed. The maximum species diversity with the greatest equalization of species was characteristic of meadows. We recommend the use of beer traps for ecological studies of Coleoptera fauna in open biotopes.

To study and conserve biological diversity is one of the most important tasks of protecting natural ecosystems. According to long-term data, the biodiversity of invertebrates of Mordovia State Nature Reserve accounts for 6823 species out of 10 types of invertebrates: Rhizopoda (58 species), Porifera (1), Platyhelminthes (156), Nematoda (67), Annelida (4), Acanthocephala (1), Mollusca (62), Bryozoa (1), Rotifera (80), and Arthropoda (6393). Thus, the Mordovia State Nature Reserve belongs to one of the hotspots of biodiversity in the forests of the temperate zone in European Russia. It is home to a large number of rare species and three endemic species. The protected area is connected by ecological corridors with other territories and can be a source of genetic and species diversity for nearby ecosystems.

Forest edges significantly influence the distribution of many beetles. In 2020–2022, in the Republic of Mordovia (Russia), we used beer traps to collect beetles in four sites, located on the forest edges, and in forest interiors. Eight traps were on each site (edge–below, edge–above, forest interior–below, and forest interior–above) with two traps per plot. The traps were located at heights of 1.5 (below) and 7.5 m (above) above the ground. More than 13,000 specimens from 35 families were recorded. There were 13 species common to all plots, including four (Protaetia marmorata, Cryptarcha strigata, Glischrochilus grandis, and Soronia grisea) in all traps. The general pattern was the highest beetle diversity on the forest edge in the lower traps, while the total number of all species on the edges was lower. At the edges, the Shannon index was almost always higher or equal to similar values in traps in the forest interior. Based on our data, the number of saproxylic beetles prevails inside forest areas, and the highest number of them was found in the upper traps. In all plots, we found a relatively higher number of anthophilic beetles at the forest edge in the upper traps.

Diptera is one of the most species-diverse insect orders. The paper presents data on the biodiversity of Diptera from 9 families (Tipulidae, Limoniidae, Pediciidae, Mycetophilidae, Keroplatidae, Ptychopteridae, Muscidae, Fanniidae, Sciomyzidae) inhabiting 14 regions within the Volga upland and Oka-Don lowland. The most studied fauna is in the Republic of Mordovia (399 species). The fauna of these families is least known from the Republic of Tatarstan, Lipetsk Region, Nizhny Novgorod Region, and Vladimir Region (9, 19, 20, and 21 species, respectively). A total of 545 species are known from 9 families of Diptera in the large macroregion. The largest number of species includes the families Muscidae (190) and Limoniidae (102). The biodiversity is least known in Ptychopteridae (4 species), Pediciidae (6 species) and Keroplatidae (10 species).
