In the middle course of the Neman River 45 species of water beetles have been found to occur. The most numerous were: Laccophilus hyalinus, Laccobius minutus, Gyrinus aeratus and Haliplus fluviatilis. The all (except L. minutus) represented lake - river element, which constituted 60% of the total number of the whole collected material. The distribution of water beetle fauna is determined, to the highest extent, by the habitat diversity of the river.
