Besides the busy butterflies there is a beacoup mouvement on the bee hotel as well. Swarms of a small bee engulf the hotel and are checking out all its nesting tunnels. They fill them up and close the entrances with mud and small stones. I’m not sure yet which bee it is.
Edit 26 september 2015: I’ve identified this bee as Heriades truncorum ¹
