Can anyone help me identify this species of wasp, please? They have excavated a sizable entrance to what I assume is a cavity in the earth. There are little balls of earth strewn at the entrance, and I can see them carrying them out. There is a tremendous amount of activity, they are coming and going every few seconds. They seem quite small; smaller than the wasps with which I am familiar.
