Abstract
The vertical distribution of insects was studied in deciduous forests of the temperate zone (the center of European Russia). During the research, 81342 individuals from 10 insect orders (Dermaptera, Blattodea, Hemiptera, Hymenoptera, Coleoptera, Neuroptera, Trichoptera, Lepidoptera, Diptera, Mecoptera) were collected. Diptera, Lepidoptera and Coleoptera were the most numerous. The total number of Coleoptera and Diptera was higher at an altitude of 1.5 m, and Lepidoptera prevailed at an altitude of 12 m. Species from the orders Hymenoptera, Dermaptera, Neuroptera and Trichoptera dominated the tree crowns. The number of Blattodea was higher in the lower tiers of the forest. The seasonal dynamics of the number of insects in traps tended to increase significantly by September. But each order had its own dynamics of numbers during the season.
