A "Bombus lucorum" posed for photographs.
No interactions present.
It is a male, so the best you can do is B. lucorum s.l. The only way you can separate males in the group is with a very expensive chemistry set!

As this is a male, shouldn't the lucorum group have yellow fluffy faces?
Ahhh! So they should!
B lucorum males with black faces?
I am confused. I am clearly hopeless at sexing bumble bees.
Is this a male? If so, what makes it a male (that is visible)? If it is a male and as its face is black it must be another species, any suggestions?
>>>what makes it a male (that is visible)<<<
It has 13 antennal segments (you can actually count them in the picture) where females have 12. Also the hind leg does not have a shiny pollen-carrying structure. And males tend to have that scattering of paler hairs you can see.
>>>as its face is black it must be another species, any suggestions?<<<
Eucera might come back on this one, but terrestris males have a black face, and the continental race, that has escaped into the wild in some places from commercially traded nests for horticultural pollination, has a white tail.
You were confused before, and this does not help!
Thank you both for your help.
Just to make sure I have understood the antennal segments count - starting from the head, the first segment is quite long, the second short, and 11 (to the tip) about the same size as each other.
That is correct. Females (queens and workers) have only 12 segments (11 becomes 10). This rule works for sexing almost all aculeates (some wasps and ants are exceptions).
I would suspect this is a Bombus terrestris male. The colour of the tail is whiter in males that in workers and queens
