I've seen these black wasps around the yard for years. Mostly noticing them digging, very quickly, into sandy soil near walls and pavers. All the other wasps built mud or paper like nests well above ground level.
The other thing I noticed was these wasps were not aggressive and simply moved out of the way when disturbed in the garden. I've never known anyone to be stung by one, but I wouldn't torment any sort of wasp just to find out.
