The article presents some results of the Hydrobiological Expeditions 2018-2019 carried out under “Russian Clean Water Project” in the Bastak Nature Reserve (Jewish Autonomous Region). The main
goal of the research was to study freshwater biota of the Bastak Nature Reserve, identify the main types
of benthic communities characteristic of various landscape-geographical complexes and longitudinal
zones of watercourses, determine the composition and structure of benthic communities, as well as
identify indicator groups and species, and estimate their bioindication significance. In the paper is
represented data of faunistic study of the air phases of three amphibiotic insect orders Ephemeroptera,
Plecoptera and Trichoptera, referred to as the "EPT indicator complex", which is considered as the very
sensitive to pollution groups of macroinvertebrates. Information about the fauna of amphibiotic insects of
the EPT complex in the Bastak Nature Reserve was practically absent until the regular hydrobiological
studies, which was begun in 2018. As a result, the first data about the Ephemeroptera and Plecoptera was
obtained, and the list of Trichoptera was significantly expanded. By now the list of revealed EPT taxa
includes 141 species belonging to 66 genera, 29 families: Ephemeroptera is represented by 35 species, 11
genera from 6 families, Plecoptera – 18 species, 12 genera from 5 families, and Trichoptera – 88 species,
43 genera from 18 families. In the article is considered the possibility of applying a new metrics – the
taxonomic structure of the EPT adult-complex as characteristic the type of habitats in various sections of
the longitudinal profile of watercourses.
