When I keyed it I assumed a Mid Band --Yellow and the terminal flashes as a lemon band thorwing up a Queen terrestris However looking at it I am in two minds so you may be right on Vestalis
Whats Happening ???

I don't think that is a band on the abdomen, it's a flash. However I'm no expert in bumbles.

It is probably vestalis (might be bohemicus, though). The tail-colour of male cuckoos (bohemicus and sylvestris at least - I don't see vestalis up here) varies from white through bright yellow to brown. I have just seen a few dozen male sylvestris, most of which had brown tails. Other times they will be mostly bright yellow or white, presumably a consequence of the genetics of the source nest.

I have uploaded a picture from the back also, hope this helps.
I would still tend to vestalis, but not with certainty. I can't make out antennal characters. Male bumbles are variable - a lot more so than females - bohemicus males often have a yellow belt, though not typically as bright as this one.
Thanks Ed / Murdo thats very useful;
I've put a few more pictures up as I have a whole nest of these bees in my garden, they just don't stay still enough for a good picture!
