Canada goldenrod Solidago canadensis as one of the most expansive invasive plants is commonly found on the territory of Poland. Not such work has been done so far on arthropods in habitats of S. canadensis in our country. The aim of the present study was to determine the number of different groups of beneficial arthropods occurring on Canada goldenrod plants. Studies were conducted at two sites in the city of Wroclaw in 2009–2010. Three observation methods were used i.e. the direct plant monitoring, counting insects over a 1 m2 frame and the sweep net. The obtained results show a high attractiveness of Canada goldenrod plants to the predatory, parasitic and pollinating arthropods, especially during the time of plant flowering. Among the predatory insects most frequently recorded were hoverflies (Syrphidae) and lacewings (Chrysopidae). In the sweep net catch the most numerous were spiders (Araneae) and parasitic wasps (Parasitica). A one of the species that also occurred on Canada goldenrod was the honeybee (Apis mellifera L.), especially with a high population density during late summer and early autumn, when the flowers of the other honey plants were already overblown. This indicates a high suitability of S. canadensis as a good supplementary source of nectar for pollinators.
