European Hornet

The European hornet is the largest eusocial wasp native to Europe. It is also the only true hornet 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. Scientific Name: Vespa crabro Range: Native to Eurasia; introduced to N. America Size: 25–35 mm Status: Native ID Notes: Brown thorax, yellow abdomen with brown markings. Largest social wasp in N. America (other than the unrelated bald-faced hornet). Behavior / Notes: Less aggressive than yellowjackets. Only true hornet in North America. Active at night — attracted to porch lights.
