In 2014 and 2015 we investigated the nesting ecology of Polistes nimpha, one of the paper wasp species common in western Poland. In three selected study plots we collected data about plant species on which P. nimpha foundresses initiate nests, nest height above ground, and nest azimuth. We have observed some preferences of foundresses in relation to these three parameters. Nests are most often initiated on Hypericum, Tanacetum, Daucus and Achillea plants. The preferred range of nest height above ground is 15 to 25 cm, while the preferred nest azimuth is about 110°.
