This article is devoted to an investigation of the local fauna of bumblebees in the lower reaches of the Northern Dvina River in northern Russia where 27 species of bumblebees were found during the present study. The basis of the local fauna of bumblebees in the lower reaches of the Northern Dvina River is related to species with a wide range. The majority of the species are Transpalaearctic. Holarctic, Sub-Transpalaearctic, whereas West-Central Palaearctic are less represented. According to the latitudinal aspect the majority of the species are temperate, and the rest are boreal and arcto-temperate. One of species found in the local fauna is subboreal. The number of species in the studied local fauna is the largest among the local faunae of the northern part of the Arkhangelsk Region. It is comparable to the local faunae of the southern part of this region. Here is recorded species such asBombussoroeensis,B.distinguedus,B.ruderarius,B.veteranus,B.humilis, and others, which are not typical of native taiga habitats but are the meadow species in the European North of Russia. Due to the wide development of meadows and ruderal communities in the lower reaches of the Northern Dvina River, these species are widely represented here. The rare species in the studied local fauna areB.patagiatus,B.humilis,B.consobrinus, andB.schrencki.

The bumblebee fauna of the Southern Taymyr region, northern Siberia, is represented by 10 species, i.e., Bombus consobrinus, B. flavidus, B. lapponicus, B. hypnorum, B. jonellus, B. cingulatus, B. balteatus, B. pyrrhopygus, B. hyperboreus, and B. cryptarum. During the field research for this study, 7 species of bumblebee on the Putorana Plateau (or the Putorana Mountains, on the northwestern edge of the Central Siberian Plateau) and 6 species near Dudinka Town were observed and B. consobrinus was found for the first time on the Putorana Plateau. To date, B. consobrinus was known only in the southern and central parts of the Krasnoyarsk Krai. Regarding the regional fauna, Transpalaearctic and Holarctic species are presented. According to the latitudinal aspect, in this region there are arcto-boreal, arcto-temperate, boreal and temperate species. An analysis of the community was carried out regarding bumblebees that live on the Putorana Plateau. It was found that species of the subgenus Pyrobombus and Alpinobombus, that are typical for the tundra and forest-tundra zones in the Northern Palaearctic, are dominant within the bumblebee community.

The fauna and ecology of bumblebees in the European North are quite well-studied. However, there is a scarcity of information about the distribution and ecology of certain species of bumblebees, especially for the territory of Northern Russia. In this study, we summarised materials concerning Bombus (Pyrobombus) jonellus (Kirby, 1802), which is typical bumblebee species for the north-western portion of the Russian Plain and surrounding areas. The studied territory includes the Arkhangelsk Region and the western part of the Nenets Autonomous District, i.e. a wide strip from taiga to tundra ecosystems. Due to the studies of materials that were collected over a period 17 years, we established that B. jonellus is widely distributed and the northern border of its range within the studied region reaches the northern part of the Kanin Peninsula. In the north-western Russian Plain, B. jonellus has been found in various types of habitats, the most common being coniferous and birch forests, secondary meadows and ruderal patches. In the Solovetsky Islands, White Sea, Russia, B. jonellus is typical on coastal heathlands. In the northern part of the studied region, B. jonellus has a tendency to forage in open habitats and visits a wide range of entomophilous plants, mostly of the family Ericaceae. Our findings highlight that the territory of the north-western Russian Plain and surrounding areas is where B. jonellus is widely distributed and abundant, being recorded in different types of habitats.

This article is devoted to a study of the fauna of the long-tongued bees in the north of the Arkhangelsk Region, which is located in the northeast of the European part of Russia, but excludes the Arctic islands. This group includes the bees of the families Megachilidae and Apidae. Forty-four (44) species of bees were found in this region. Most of them (29) are bumblebees (genus Bombus). Fourteen (14) species are megachilid bees (genus Osmia, Coelioxys and Megachile) and one species is Apis mellifera. The largest number of species (39) was recorded in the lower reaches of the Northern Dvina River, due to the long research on this territory. The lowest number of species (16) was recorded in the Mezensky District. In the north of the studied region, the tundra species of B. lapponicus is only presented for the Mezensky District. Many species of bumblebees in the regional fauna belong to the ecological group of the meadow species. These are B. soroeensis, B. ruderarius, B. rupestris and a number of others. They are typical for meadow and ruderal habitats, and are usually not presented in the native taiga habitats. These meadow species are widely represented in the valleys of large rivers, such as the Northern Dvina, the Onega, and the Mezen. Compared to bumblebees, megachilid bees are much rarer in the north of the Arkhangelsk Region. Apis mellifera is presented in the lower reaches of the Northern Dvina River, but here it is rare, compared to the southern part of the Arkhangelsk Region.
