Value of species
One of 51 species of the subgenus Thoracobombus. One of 250 world known species of the genus Bombus, and one of 40 bumblebee species in the fauna of Ukraine.
Distribution: Palaearctic, Oriental Regions.
[[Bombus laesus belongs to the laesus-group (formerly sg. Laesobombus), together with the near species or subspecies Bombus mocsaryi. Depending on the authors, these two species are separated or lumped together as subspecies of the same taxon laesus. As the queens and workers of laesus s.s. very closely recall those of B. muscorum, to the point that they can be undistinguishable, one should rely only on the males in the region where these species co-occur.
Bombus laesus s.s. is present in S.-E. Poland, Hungary, a few isolated specimens in Serbia and Macedonia, in Ukraine, the Volga basin, Kazakstan, the Caucasus region, Anatolia and N.-W. Iran. Within this wide range, the species is common only in some rather restricted zones, as Hungary and the region extending from Turkey to Iran. The steppic distribution of Bombus laesus laesus reminds of that of an other steppe species: Bombus fragrans]].
[[Bombus moscaryi belongs to the laesus-group (formerly sg. Laesobombus), together with the near species or subspecies Bombus laesus. Depending on the authors, these two species are separated or lumped together as subspecies of the same taxon laesus.
Bombus mocsaryi is very widely distributed: N. Africa (Morocco, Algeria and Tunisia), Spain, S. France, E. Austria, Hungary, Poland, Baltic states, Belarus, N. Ukraine and Russia (mainly between the 50th and 60th parallels). Scattered specimens have been collected in Croatia, Serbia, Macedonia, Greece and Romania. Curiously, the species is known neither from Italy nor from Bulgaria. There is a gap between the western populations (Spain, France and N. Africa) and the populations from E. Europe.
More east, B. mocsaryi is found here and there, from W. Siberia to the Pacific coast.
Bombus mocsaryi does not occur in true steppe (contrary to laesus s.s.) but in wooded steppe or in dry open grassland]].
