European Hornets Vespa crabro are the largest paper wasps in North America. If you are allergic to Wasps such as the Bald –faced Hornet, you are probably allergic to this species too, the proteins in the venom are not identical, but they are similar. They are reputed to be quite docile (as social wasps go). Our database is growing every day, we hope to have this species in the future. I have included a link from Germany which describes the gentle nature of these insects.
