On Wednesday 21.06.2023, I gave an online seminar on the diversity of wild bees (in German). The recording is now available at https://bluehende-naturparke.de/fachseminare/.
There are almost 600 species of wild bees in Germany; their diversity is impressive! While they differ in size, the time at which they fly, the way they nest, their food sources and much more, they all directly or indirectly depend on the abundance of flowers in our environment.
