The studies were carried out at the Experimental Station of the Agricultural University in Wrocław in 1998-2002. The aim of the study was to compare the species spectrum of hoverflies (Diptera, Syrphidae) collected by different methods. Four methods were applied: collection in yellow water traps, sweeping, direct collection, and rearing of the pupae collected directly from cultivated plants in the field. In the yellow traps, various and numerous species of Syrphidae were captured, but weather conditions had strong effect on their abundance. In some years, in yellow traps there were found species (Metasyrphus corollae, Melanostoma mellinum) that only foraged for food or were on migration towards south of Europe and that were absent or scarce among hoverflies reared from the pupae. Hoverflies collected using a sweeping net or directly were usually not numerous and represented mainly two genera: Sphaerophoria and Melanostoma.
