Material of 203 acalyptrate species swept on grazed and/or mown moist meadows and a wet non-harvested forest meadow was compared to that sampled on Warsaw city lawns. A closer relationship of the mesophilous meadow acalyptrate community with that found on urban grassy areas than that on the boggy meadow was noted. Fertilization of moist meadows with domestic ungulate droppings brought about an increase in abundance of these flies as well as the prevalence of saprophages, Sphaeroceridae in particular, active since early spring till late autumn. The first dominant of the whole taxocoene was phytosaprophagous Leptocera nigra, outnumbering even Scaptomyza pallida. Among coprophages, Sepsis spp. prevailed, mainly 5. flavimana and 5. cyni- psea. Phytophages were dominated by Agromyzidae and the association of graminivores, especially by Cerodontha denticomis, outnumbering Chromatomyia nigra and Opomyzidae (Opomyza gemiina- tionis). Among the remaining plant feeders the dominants were species mining composite plants, especially Phytomyza wahlgreni. As regards the acalyptrate individual number on the moist mea? dows, wide-range zoogeographical elements dominated over the European one, which prevailed on the wet forest meadow.
