The emergence of amphibiotic insects from a beaver pond in the upper reaches of the Khoper River in Penzenskaya oblast of Russia is investigated. 29 fly species from 9 families of Brachycera were found. The biotopic distribution, abundance, biomass, seasonal dynamics of emergence and the role of Brachycera in transferring biomass from water to soils are analysed.

KEY WORDS: the Khoper river, Russia, Diptera, Brachycera, emergence, removal of biomass, abundance.
