I know this is going to be a difficult one but I should have the opportunity to photograph them again and maybe get better pictures. I am guessing Digger Wasp because it looks like a wasp and it was digging. My little book says that there are 110 species. It also says they are solitary wasps and in the last picture there was a jam of them all trying to get in the same hole.
