It has a white or "baldfaced" head, which is the source of its colloquial name. These wasps also have three white stripes at the end of their bodies. They are notably larger than other species of "Dolichovespula", as adults average about in length. Queen and worker wasps have similar morphologies. However, workers are covered by small hairs while the queen remains hairless. Queens are always larger than workers in their colonies, though size distributions can vary
Bald-faced hornet in different nests and workers in one colony might be as large as a queen in a different one. "D. maculata" create egg-shaped, paper nests up to in diameter and in length. Nests are layered hexagonal combs covered by a mottled gray paper envelope. Bald-faced Hornets create this paper envelope by collecting and chewing naturally occurring fibers. The wood fiber mixes with their saliva to become a pulpy substance that they can then form into place.
