One species of wasp which builds its nest in the ground and is known for particularly aggressive behavior is known as a "yellow jacket".  Two different varieties are often called "hornets": one of them is the European hornet which is large (up to 1 1/2 inches), relatively gentle although they do sting, and black and yellow in color. Another is the North American hornet which is black and white in color, notoriously aggressive in behavior, and builds large football-shaped nests in trees.
