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.

During the 2008-2009 time period, the effect of phacelia grown with broad bean on the presence of Syrphidae in colonies of Aphis fabae Scop. as well as the attractiveness of phacelia flowers for syrphid adults was researched. In A. fabae colonies, 9 Syrphidae species were collected. On plots with phacelia, less aphids and more syrphid larvae, compared to the homogenous crop, were observed. The dominant species were: Episyrphus balteatus, Shaerophoria scipta, Syrphus ribesii and Epistrophe eligans. Among the 9 species of Syrphidae collected from tansy phacelia flowers, the same species dominated as those noted in A. fabae colonies on broad beans intercropped with phacelia. Sowing plants of value to Syrphidae, such as phacelia, is probably the ideal habitat management option for early occurrence of syrphids. Such a practice result in the reduction in crop damage by aphids.

Chalcosyrphus eunotus is one of the most endangered saproxylic hoverflies in Poland. Almost 80 years since its first record in Pomerania, this fly has been found in a few new localities in Poland: Ojców National Park, Białowieża Primeval Forest, and in the vicinity of following cities: Toruń, Gdańsk, Łódź and Inowłódz. The actual map of its range in Poland is presented and the current state of knowledge of its phenology, ecology, behavior and conservation status is discussed. The authors advance the hypothesis that the increasing occurrence of Ch. eunotus is directly proportional to an increase in the number of beavers over the last 20 years.
