The European Hornet is the largest wasp species in Europe, measuring up to 1.4 inches. It features an easily recognizable yellow and brown coloring, which resembles an oversized yellow jacket.

Despite their size, they are typically non-confrontational unless provoked. They have adapted well to regions such as Europe, Russia, North America, and Northeast Asia.

They construct their nests in hollow trees using a combination of chewed wood pulp and saliva. However, they will also occupy barns, sheds, and attics if no hollow trees are available. 

Their colonies can consist of 200 to 700 members, and they have a strong community culture. These hornets hunt large insects such as beetles and yellow jackets and enjoy honey and fruit juices.
