Bald-faced hornet coloring differentiates it from its mostly black and yellow genus mates. Baldfaced hornets are distinguished from other yellowjackets by their white and black coloring. 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.
