Erstnachweise und Wiederfunde verschollener Stechimmenarten (Hymenoptera Aculeata) in Schleswig-Holstein

Especially intensive collecting activities of the AG Stechimmen Schleswig-Holstein during the years 2016-2022 resulted in the discovery of 37 species of wild bees and aculeate wasps (Hymenoptera Aculeata) that were recorded for the first time in Schleswig-Holstein, Germany, as well as the rediscovery of 19 species that were considered extinct for this region. The newly discovered species are discussed regarding their known distribution in neighbouring regions. In particular, a strong northward dispersal of thermophilic species can be observed, presumably due to climate warming.
