The article presents the results of research on the study of beetles in the north-western regions of Uzbekistan from a general biological and faunistic point of view. In particular, the research was conducted from 2018 to 2021, the role and methods of research, the periods of activity of adult buzzards, the faunistic and taxonomic structure of buzzards in the north-western regions of Uzbekistan. In the north-western regions of Uzbekistan, the faunistic composition of the beetle family consists of 104 species and subspecies belonging to 39 genera of 7 subspecies. An analysis of the biodiversity of these identified beetles in the subgroups revealed that Harpalinae, which included 32 species at most 19 generations, belonged to the Omophroninae subfamily, at least 1 gene 1 species, and less than 2 genera 5 species to the Broscinae subfamily. According to the article, the distribution of beetles by regions is 36 (34.6%) in Ustyurt, 59 (56.7%) in the Kyzylkum desert, 30 (28.8%) in the Amudarya biosphere reserve, and 52 (50%) in agrocenoses. . The above data are of great theoretical and practical importance in the study of the fauna of the relatively little-studied buzzard beetles of northwestern Uzbekistan.
