Size: 2–3.5 cm
Appearance: Hornets are distinguished from other wasps by the wider heads and larger and more rounded abdomens. All hornets have two sets of wings and a long slender body, a stinger, drooping legs in flight, and an extremely thin waist between the thorax and abdomen.
Habitat: Most species make exposed nests in trees and shrubs, but some build their nests underground or in other cavities.
Potential Harm: Hornets have stings used to kill prey and defend hives. Hornet are very aggressive and stings are more painful to humans than typical wasp stings because hornet venom contains a large amount of acetylcholine. Individual hornets can sting repeatedly, unlike honey bees, hornets and wasps do not die after stinging because their stingers are not barbed and are not pulled out of their bodies. People who are allergic to wasp venom are also allergic to hornet stings.
