Description	The aim of this study was to evaluate the effects of water chemistry, substrate, and discharge on taxonomic composition of Diptera larvae in small, treeless spring fen sites throughout the whole range of mineral-richness gradient.In total, 9547 individuals of 163 taxa belonging to 26 families were found. Chironomidae (62 taxa) was the most taxa-rich family followed by Psychodidae (22 taxa) and Limoniidae (19 taxa).Using the permutation multivariate analysis of variance (PERMANOVA), the gradient of basicity, median diameter of inorganic particle size (Q50) and water temperature were the most significant factors for Diptera assemblages in habitat A, whereas the gradient of basicity together with the content of Fe determined the Diptera assemblages in habitat B.
