About 30 species of eusocial Apinae and 11 species of eusocial Polistinae and Vespinae are possible inducers of venom allergies in Germany. Twenty-three of these species occur regularly or occasionally in residential or recreational areas. Geographical and altitudinal distribution, phenology, nest sites and foraging habitats of these species are concisely characterized. Their defensive behavior is described.
