75 species belonging to five families of Calyptrata were recorded in the pine forests of the Berezinsky Biosphere Reserve. In pine canopies and the herb layer in one site, and in pine canopies only in two other sites were recorded the following: 8 species of the family Muscidae (Muscinae), 16 species of the family Calliphoridae, one species of the family Rhinophoridae, 13 species of the family Sarcophagidae and 37 species of the family Tachinidae. Most of them are widely distributed saprophages and parasitoids as well as predators of invertebrates and vertebrates. All the species recorded now in the families are new to the region studied. 30 of them are synanthropes. The fauna of Calliphoridae, Sarcophagidae and Tachinidae of the pine forests of the Berezinsky Biosphere Reserve in Byelorussia was compared to the fauna of blow flies, flesh flies and tachinid flies in a pine forest in the Kampinoski National Park in the Mazovian Lowlands in Poland.
