The white-faced hornet is a large wasp and is widespread throughout North America. It is black and white in color. They usually build their nests in trees or shrubs. By the end of the summer these nests can be very large. The adults are much larger than yellowjackets and have whitish markings.
Colonies usually become established in late May and decline by September. Nests are usually found in shrubs, vines or trees and occasionally on power poles, houses and other man-made structures. The number of workers in an active colony at any one time can be as high as 600. Adults prefer live prey especially flies. This species is not a significant pest unless located in close proximity to sites of human activity.
Adult Activity Period: April – September
