The paper summarizes the results of amphibiotic studies in 96 left-bank tributaries of the Lower Amur. The total species list includes 295 taxa of invertebrates belonging to 5 types and 9 classes. Mayflies (51 taxa), stoneflies (33), caddis flies (62) and chironomids (128) make the basis of the taxonomic diversity. According to the types of distribution, Palaearctic species (75.4%) dominate, and Holarctic species occupy a secondary position (24.6%).
