In a changing climate, phenological observations are gaining new importance. They can tell what changes are taking place in certain environmental conditions. The studies were conducted in 2019 within the territory of the Republic of Mordovia (the center of the Euro- pean part of Russia). Beer traps (beer as a bait) were used to collect Diptera. The material was collected in the period from April to Octo- ber in different forest biotopes (pine forest, lime forest, aspen forest, birch forest and oak forest) and the air temperature was recorded at the same time. In total, more than 14.000 specimens of Diptera were recorded. Overall, 29 families were recorded. The largest number of families was observed for birch (23 families) and pine (24 families) forests, the smallest number – in aspen forest (16 families). The families Muscidae, Drosophilidae, Calliphoridae had the largest number of captured individuals (44.5%, 35.2%, 7.6% of the total number of individuals respectively). The highest number of individuals was captured in oak forest. The dynamics of abundance in all biotopes were similar and were characterized by the same number of declines and rises. The first small significant peak in the number of Diptera occurred in the first half of summer. A slight increase in the number of specimenі occurred in mid-June. In the second half of September, there was a gradual increase in the number and the maximum peak was recorded in mid-October, then there was a decline. The autumn increase in the number of Diptera in all five biotopes exceeded the summer peak by several times. This dynamic was typical for most families. However, species from the family Lonchaeidae had the peak in July. For our better understanding of the changes in the seasonal dynamics of the number of Diptera, long-term observations in different climatic zones are needed.

Studies on the vertical distribution of arthropods in temperate forests have revealed the uneven vertical distribution of communities. Many factors influence these patterns simultaneously. However, there are still many questions related to the vertical distribution of Coleoptera in deciduous forests of the temperate zone. The research was carried out within the territory of the Republic of Mordovia (the center of the European part of Russia). Fermental traps with a bait made of fermenting beer with sugar were used to collect Coleoptera. The collections were carried out from May to September 2020 at five sites in a deciduous forest. We set traps at a height of 1.5, 3.5, 7.5 and 12 m above the ground) on the branches of trees. Ninety-two species were identified at the end of studies at different heights. The families Nitidulidae (15 species), Cerambycidae (14 species), Elateridae (7 species), Curculionidae (7 species) and Scarabaeidae (7 species) had the greatest species diversity. The greatest species diversity was recorded at a height of 1.5 m, while the smallest one was recorded at a height of 7.5 m. The minimum number of specimens was recorded at a height of 12 m. The largest differences in the Jaccard similarity index were obtained between samples from a height of 1.5 and 12 m. The Shannon’s diversity index was higher near the ground than in the tree crowns (at heights of 7.5 and 12 m), and the Simpson index had the opposite tendency. Glischrochilus hortensis and to a lesser extent Cychramus luteus preferred to live in the lowest layers of deciduous forest (1.5 m). Cryptarcha strigata was mainly found with relatively high numbers at heights of 3.5 m and 7.5 m. The abundance and occurrence of Protaetia marmorata and Quedius dilatatus were higher in the uppermost layers of the crowns. The number of saproxylic beetle species at heights of 3.5–12 m was almost the same, while in the surface layer it decreased. The number of anthophilic beetle species was also lower at a low altitude. Our data confirm the relevance of sampling in forest ecosystems at different altitudes while studying arthropod biodiversity.

Муравьи представляют собой одну из ключевых групп насекомых в большинстве наземных биоценозов. Изучение видового разнообразия муравьев является актуальным направлением эколого-фаунистических исследований, направленных на поддержание биоразнообразия. Особое внимание уделяется особо охраняемым природным территориям, где, как правило, наблюдается высокое видовое разнообразие муравьев. Сбор мирмекологического материала в Мордовском заповеднике проводился в 2014–2020 гг. вручную, в ходе маршрутных учетов и учетов на углеводных и белковых кормушках. Приведен аннотированный список муравьев Мордовского заповедника, включающий 42 вида из 11 родов трех подсемейств (из них 17 видов приводятся впервые для Мордовского заповедника). Большинство видов относится к родам Formica, Lasius, Myrmica, которые вместе составляют около 75% видового богатства муравьев в Мордовском заповеднике. Зоогеографический спектр мирмекофауны представлен семью типами ареалов с преобладанием европейско-западносибирского и северно-палеарктического. Анализ разнообразия муравьев проведен с использованием профиля разнообразия Реньи на основе данных маршрутных учетов. Особенности биотопического распределения муравьев оценены с помощью бестрендового анализа соответствия. Выявлена средняя степень выровненности видов, что определяет относительно высокое видовое разнообразие муравьев в Мордовском заповеднике. Наибольшие отличия по видовому составу муравьев демонстрируют сосняк ландышевый, березо-елово-липняк осоково-снытевый, суходольный луг с преобладанием Poa pratensis и пойменный луг с преобладанием Lupinus polyphyllus, что обусловлено оптимальными микроклиматическими условиями для поселения отдельных видов. Видовая плотность муравьев на модельных полигонах в среднем составляет 7 видов/100 м2

Wildfres considerably afect forest ecosystems. However, there is a lack of data on the post-fre status of insect communities in these ecosystems. This paper presents results of a study conducted in 2019 which considered the post-fre status of the insect fauna in a Protected Area, Mordovia State Nature Reserve (Republic of Mordovia, centre of European Russia), considered as regional hotspot of insect diversity in Mordovia. We sampled insects on intact (unburned, control) and fre-damaged (burnt in 2010) sites and compared the alpha-diversity between sites. In total, we sampled and analysed 16,861 specimens belonging to 11 insect orders, 51 families and 190 species. The largest orders represented in the samples were Coleoptera (95 species), Diptera (54 species), Hymenoptera (21 species), and Neuroptera (11 species). Other insect orders were represented by between one and four species. The largest four orders (Coleoptera, Lepidoptera, Diptera and Hymenoptera) represented 96.7% of all studied specimens. We found that in the ninth year after low intensity surface fre damage, the insect diversity had returned to a similar level to that of the control (unburned) sites. Sites damaged by crown wildfre difered considerably from other sites in terms of a negative impact on both species diversity and the number of specimens. This indicates the serious efect of the crown fres on the biodiversity and consequent long-term recovery of the damaged ecosystem.

The natural range of the Asian ladybird Harmonia axyridis (Pallas, 1773) covers the territories of China, Mongolia, Korea, Japan, and Russia (Far East, Southern Siberia, and Altai). Since the early 1980’s, the global invasion of H. axyridis began, first on the territory of the United States, from where the Asian ladybird spread to South America, Africa, and Europe. By 2016, this species occupied all of Western Europe with the exception of its northern and southern regions. Penetration of H. axyridis on the territory of the Russian Federation (Kaliningrad) was discovered in 2010, and since 2011, the species has spread to the Black Sea coast. This report presents our data on the distribution of Harmonia axyridis in central Russia, from its western borders, to the Volga River. The occupation of this huge territory by this species occurred mainly in the last 3 years−2018–2020. The rate of movement of the species on the territory of the European part of Russia is about 200 km/year.

Protected areas are organised in different climatic zones, which usually include typical ecosystems characteristic of certain climatic zones. In most cases, protected areas are biodiversity hotspots. These areas are benchmarks in terms of nature conservation and to determine their biological diversity is becoming an important task. It is important to investigate the carabid family of protected areas within the framework of understanding the overall biological diversity of these systems. In addition, ground beetles, as one of the largest groups of ground-based inhabitants, are indicators of the state of ecosystems and serve as markers of their well-being. We present 2,969 new occurrence records comprising 226 species of Carabidae, belonging to eight subfamilies, from the Mordovia State Nature Reserve (central Russia). Ten species are listed for the first time for the Mordovia State Nature Reserve fauna after previous research: Cicindela maritima, Bembidion striatum, Dyschirius angustatus, Dyschirius arenosus, Notiophilus aestuans, Bembidion argenteolum, Bembidion velox, Bradycellus caucasicus, Cymindis angularis and Syntomus truncatellus, five of which were first recorded for the Republic of Mordovia (Egorov et al. 2020). Previously, this information was not published anywhere and we wanted to make it available to everyone by embedding it in the global database on biodiversity (GBIF).

The species diversity of ground beetles (Carabidae) was studied in the meadow ecosystems in the center of European Russia (Nizhniy Novgorod region and the Republic of Mordovia). Seventeen localities were studied. All meadow biotopes were divided into four types: dry meadows, dry meadows adjacent to forest shelter-belts, wet floodplain meadows, and floodplain meadows affected by livestock grazing. The highest species diversity was in dry meadows adjacent to forest shelter-belts (65 species) and wet floodplain meadows (62 species). The lowest number of species was in floodplain meadows affected by livestock grazing (24 species). Forty ground beetle species have been identified in dry meadows. Wet floodplain meadows had the highest Shannon’s index, and the lowest Simpson index. The ground beetle fauna had high values of the Simpson and Berger-Parker indices in dry meadows. Only two species dominated in dry meadows, while four to seven species dominated in other habitats. According to the Jaccard similarity index, the most similar species composition of ground beetles was in dry meadows and dry meadows adjacent to forest shelter-belts. By reducing the number of species and specimens of ground beetles, trampling has a great effect on the fauna of floodplain meadows affected by livestock grazing.

The seasonal activity of Coleoptera was studied using fermental crown traps. The study was conducted from April to October 2019 in five forest biotopes (aspen, lime, pine, birch and oak) in the territory of the Mordovia State Nature Reserve (Russia, Republic of Mordovia). Eighty-three species are found from 31 families. Cerambycidae (13 species), Nitidulidae (11 species) and Curculionidae (9 species) had the greatest species diversity. A significant part of the identified taxa (57 species from 23 families) can be attributed to saproxylic beetles. The peak abundance of Coleoptera in four biotopes (aspen, lime, pine and birch forests) was in mid-May; in an oak forest, it was at the beginning of June. Seven species seasonal activity was monitored (Cryptarcha strigata, Glischrochilus hortensis, Glischrochilus grandis, Cychramus luteus, Soro- nia grisea, Protaetia marmorata and Anisandrus dispar).

Seasonal dynamics of the activity of Carabus coriaceus (Carabidae) imago was studied in the eastern part of the areal (in mixed and pine forests in Mordovia State Nature Reserve and National Park “Smolny”, Re- public of Mordovia). Seasonal activity varied by year. It started from late April in 2018 and early May until mid-September and October. The peak number was recorded in the second half of July-August. In the warm spring of 2018, the timing of the start of activity was shifted to April, while in the cold spring of 2019, the ground beetle began activity only in early May. The catchability of C. coriaceus was higher with- in the territory of Mordovia State Nature Reserve comparing to the National Park “Smolny”. This may be due to the fact that Mordovia State Nature Reserve ecosystems have been protected for a longer time. In this protected area, anthropogenic activity ceased more than 80 years ago and the ecosystems have fully recovered.

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. 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.

The possibilities of applying various methods to study Coleoptera give unexpected and original results. The studies were carried out with the help of fermental crown traps in 2018–2020 on the territory of eight regions in the central part of European Russia. The biodiversity of the Col-eoptera that fall into crown traps includes 294 species from 45 families. The number of species at-tracted to the fermenting bait is about a third of the total number of species in the traps (this is 97.4% of the number of all of the caught specimens). The largest number of species that have been found in the traps belong to the families Cerambycidae, Elateridae and Curculionidae. The most actively attracted species mainly belong to the families Cerambycidae, Nitidulidae and Scarabaeidae. The species of these families are equally attracted by baits made of beer, white and red wines. In order to identify the Coleoptera biodiversity of a particular biotope, two-year studies are sufficient, and they should be carried out throughout the vegetation season. Especially good results can be ob-tained from studies of rare species that are actively attracted by such baits. It is possible to study the vertical–horizontal distribution of Coleoptera fauna in individual biotopes.

The research was conducted in 2019-2020 inthe Republic of Mordovia (European part of Russia). In order to collect Lepidoptera, beer traps were used where beer served as bait. The field surveys were carried out from April to October in variousforest habitats.The air temperature was recorded. To elucidate the spatial distribution of Lepidoptera, varioushabitats were examined intwo study plots. In total, more than 23 thousand Lepidoptera specimens were examined.The largest number of Lepidoptera was collected inoak forestsin contrast to the four other forest habitats. In all habitats,population dynamics were similar and characterized by the same trends of decreaseand increase. During the season, there were threepeaks of abundanceforthis group. A moderate first peak was recorded inthe second half of May, whilethe maximum peak occurred in the first half of July. Autumn population peaks depend on temperature, while spring and summer peaks are associated with the flight of imagos and an increase in the lepidopteran abundancein habitats. In open habitats, the abundanceof Lepidoptera was lower. On forest edges,the number of Lepidoptera considerablyexceeded one in open habitats (river sandbanks, willow thickets, forest glades, and floodplain meadows) and closed habitats (inside the forests). Forest edges are a hotspot of Lepidoptera abundance and biodiversity in forest habitats. According to the vertical gradient, the number of lepidopteranswas higher at the heightof 7.5 m than at the heightof 1.5 m. At the lowerheight, the numberof Lepidoptera did not vary as considerablyas at higher heights.
