Hornets

A close-up image of a bee with translucent wings, black and yellow striped abdomen, and antennae, isolated on a black background.

Not to be confused with honey bees, hornets can be aggressive and will sting repeatedly if threatened. They build gray, football-shaped, papery nests in trees, bushes, and sometimes on the outside of buildings. Hornet nests are largest in the late summer and early fall.
