Abstract: The diversity of the terrestrial earthworm community was studied at two freshwater lakes in Sofia. Eight earthworm species were found, most of them being widespread. Only two of the species are common in both of the lakes. The higher species number was recorded in the surroundings of the lakes. The size and the location of the lakes, the soil texture and the impact of the inundations of the lake surroundings are discussed as possible factors causing these differences.
