ABSTRACT. 151 species from 9 orders of the aquatic insect fauna in the main tributaries of Zapadnaya Dvina river, Belarus, are registered, namely: Collembola — 3; Plecoptera — 11; Ephemeroptera — 26; Trichoptera — 37; Odonata — 18; Megaloptera — 1; Heteroptera — 21; Coleoptera — 32 and Lepidoptera — 2 species. The most rich in species number are Trichoptera — 23.84 %, Coleoptera — 21.19 % and Ephemeroptera — 16.55 %. High abundance of rheophil species indicates a fairly good quality of water in the studied watercourses. The most rare for the fauna of Belarus are the following species: Marthamea vitripennis (Burmeister, 1839); Isoptena serricornis (Pictet, 1841), Xanthoperla apicalis (Newman, 1836), Brachyptera risi (Morton, 1894), Normandia nitens (Mulller, 1817) and Potamophilus acuminatus (Fabricius, 1792).
