These are kleptoparasites of Andrena mining bees. You can quite often see them searching for Andrena nests at ground level or even entering them them to lay their eggs. Can't help with the actual species I'm afraid. (Many species of Nomada are associated with a particular species of Andrena so if you know which Andrena are in the area that can help.)
Thanks for the additional information
I have put some Andrena photos on iSpot too from the same location but it is hard to identify them from photos it seems
