The European hornet (Vespa crabro) is the largest eusocial wasp native to Europe. It is also the only true hornet (genus Vespa) found in North America, having been introduced by European settlers in the 1800s. Although hornets are mistaken for being aggressive and dangerous beings, they are actually calm and will not purposefully seek to harm you or your family. heir sheer size - between 2-3 cm's for workers and males, 3-4cm's for queens - and riotous buzz can however make them an intimidating proposition.
