The purpose of this research is to study ecological and zoogeographic structure of the beetle and bug communities on cretaceous slopes under different anthropogenic impacts. On cretaceous exposures of the south of Belgorod region 117 species of beetles belonging to 19 families and 49 species of bugs belonging to 10 families were found. There are 14 types of area beetles and 5 types of area bugs related to 3 groups: multiregional, holarctic and palearctic. Influence of slope microzonality of the cretaceous landscapes on distribution of beetles and bugs were found. Both species diversity and relative abundance of the beetles and bugs increase from the near-watershed site of a slope to its foot, the abundance of forest-meadow and steppe-meadow species increase. The results obtained can be used for development of a database for monitoring of the condition of steppe communities in Middle Russian Upland.
