this was news to me.
I am wondering whether the bee in the photos immediately above and below is Bombus hypnorum. It certainly has the foxy-red thorax, black abdomen and white tail. I have included the photo above to show the tail. It was a highly active insect and had no wish to pose for the camera! You can see from the yellow sac just how much pollen was being collected. I don't think it was stripy enough for a Carder Bee.
