A number of these bees were busy digging holes in the sandy soil outside the holiday chalet. There was also a more orange/yellow version in the dunes.
No identification made yet.
No interactions present.
You would need to look at there work and see which ones are doing it and get pictures of the orange ones like the one i had identified a while ago.
I am not expert enough to get a scientific name for that one though. The males and females look very different.
