Brown-banded Carder Bee in Cambs? (1 Viewer)

We have a very bee friendly meadow and garden north of Cambridge. There are lots of Wite-tailed Bumblebees (the white on the back is not a trick of the light, the others are all normal), Red-tailed Bumblebees and a variety of others. I think we have Common Carder Bees but is it possible that the 1st attached picture is a Brown-banded Carder?

Common Carder Bee (Bombus pascuorum), Red-tailed Bumblebee (Bombus lapidarius) and Southern Cuckoo Bumblebee (Bombus vestalis)

the third one is Bombus terrestris

Southern Cuckoo doesn't even feature on my FSC/Buglife laminated guide. Is their an ID field guide and/or website that folk would recommend?

I have a few more pics of no 3, mostly flying I'm afraid. The white patch caught my attention but I definitely hadn't homed in on Buff-tailed. How would I separate terestris and lucorum? the only clue in my guide is position of the wings relative to the black yellow band borders - yellow back to the wings on lucorum?

Apart from the white patch, it was/is very similar in appearance, size and behaviour to bees I originally believed were White-tailed and was feeding on the lavender alongside them and some Red-tailed.

Ah fair enough, that was the only other option I guess In reply to the OP, lucorum wouldn't show the thin yellowish border at the base of the white "tail"
