In the spring/summer and autumn season of 2010 dynamics of macrozoobenthos structure of Moravica River was investigated after the changes in habitat caused by floods. It was found that macroinvertebrates are represented with 13 groups and 64 taxa from 54 genera. Trichoptera fauna was represented by 11 species, Diptera 10, 8 Ephemeroptera, Odonata 5, 6 Oligocheata, Gastropoda 5, Crustacea 3, 2 Hirudinea, Bivalvia 2 and Turbellaria 1. In average 11 taxa was identified in samples. Most abundant were Gammarus pulex fossarum, Grammarus balcanicus, Asellus aquaticus and Chironomus thumma. Abundance of macroinvertebrates at the downstream direction was increasing and was correlated with decreasing number of taxa especially in the spring season. Species are equal in number to the initial sites, and downstream a smaller number of species dominated. Average value of N-index was 2.1 which points to relatively favorable structure of macroinvertebrates. Average value of C of 0.32 indicates increased dominance of individual species. Saprobity index ranged from 1.6 to 3.5 at average of 2.3.
