Unlike other wasps, they do not have stripes or other markings. They have the standard wasp body with large wings, large head and eyes, a very tiny, thin waist and then a large back end. What sets the great black wasp apart from others is that they can grow up to 1 – 1.3 inches in length.
Ny niece, Lena, said they look like Faries when she saw them.
