The bald-faced hornet is a large, black and white insect which is widely distributed in Virginia. The nests are constructed of the same paper like material as that of other wasps. They differ a great deal from other wasp nests in being enclosed in a thick paper ball. There is a single opening at the lower end of the nest; this is always guarded by a few hornets. Nests are abandoned at the end of the season. The oval shaped nests are often quite large and are usually found attached to limbs of trees and buildings.
Hornets are beneficial; they prey upon flies and caterpillars. Unfortunately they can be a potential health hazard to people allergic to their stings.
