Habit: Hornets build gray, paper nests with many compartments, and a papery outer covering, which may hang near ground level or very high in trees, shrubs, vines, overhangs, sheds, and utility poles.
Diet: These insects eat some tree sap, but they are also accomplished predators. A hornet hive will eliminate many flies, bees, and other insects.
Reproduction: The queen tends to the reproduction. She will produce more workers to expand the hive and then, before she dies, yield a breeding generation of new queens and males (drones) to restart the cycle of life.
Other: Workers defend their hive with potent stingers. Though these insects do not sting humans unless provoked, some people are allergic to their venom and can have very dangerous reactions to a sting.
