Antique engraved illustration of the European hornet. Vintage illustration of the European hornet. Old engraved picture of the Vespa crabro. The European hornet & x28;Vespa crabro& x29; is the largest eusocial wasp native to Europe. It is also the only true hornet & x28;genus Vespa& x29; found in North America, having been introduced to the United States and Canada from Europe as early as 1840. Vespines, such as V. crabro, are known for making intricate paper-like nests out of surrounding plant materials and other fibers. Unlike most other vespines, reproductive suppression involves worker policing instead of queen pheromone control, as was previously thought. This species stings in response to being stepped on or grabbed, but generally avoids conflict. It is also defensive of its nest and can be aggressive around food sources. Care should be taken when they are found in these circumstances, as they may sting without warning. European hornets are largely carnivorous and hunt large insects such as beetles, wasps, large moths, dragonflies, and mantises. They also feed on fallen fruit and other sources of sugary food. Mutual predation between medium-sized hornets and the Asilidae & x28;robber flies& x29; is often reported.
