Are there bee hunting wasps?
Beewolf
Beewolves (genus Philanthus), also known as bee-hunters or bee-killer wasps, are solitary, predatory wasps, most of which prey on bees, hence their common name. The adult females dig tunnels in the ground for nesting, while the territorial males mark twigs and other objects with pheromones to claim the territory from competing males.
Vespula austriaca
Vespula austriaca is an obligate parasitic wasp, parasitizing the nests of other species in the genus "Vespula". Its common host species include "V. acadica" in the United States and "V. rufa" in Europe, Japan, and East Siberia. It is sometimes called the cuckoo yellowjacket wasp due to its inquiline lifestyle. "V. austriaca "wasps pollinate orchids. They differ from other parasitic wasps in their intensely aggressive behaviour during invasion and occupation of the host colony. Several morphological adaptations such as bigger body parts and more curved sting shafts are observed in these wasps to aid their aggressive parasitic behaviour. Once they occupy a host's nest, "V. austriaca" are known to engage in mauling and chasing of host workers and forced trophallaxis. Larvae will feed on spiders and other insects. Female wasps will also force host workers to feed and take care of their brood .
