Hello, this morning I saw a large Bumble Bee with a ginger thorax and very clear white tail - I'm very new to identifying bees but I thought it might be a Tree Bumble Bee? Unfortunately it had disapeared by the time I'd fetched the camera

.
It was acting pretty much like the other Bumbles I could see (collecting nectar from hardy geraniums,) and our garden backs onto a smallish patch of mixed deciduous wood in South Yorkshire if that helps.
