Abstract
The qualitative composition and quantitative characteristics of the syrton allochthonous fraction in one of the rivers of the Russian Far East were examined. It was assumed that the revealed daily dynamics of the terrestrial invertebrates drift was determined by the specifics of their daily migrations on land. A counterargument to the theory of the zoobenthos night drift strategy as a way to avoid drift-feeding predators was suggested.
