Black bee on Coltsfoot

Observation - Black bee on Coltsfoot. Description: I haven't been able to get anywhere with the identification of this bee, taken in early March at Bookham Common. As the Coltsfoot flowering season is not so far away, I'll be looking for this one again. Any guidance on possible identifications for the bee

I haven't been able to get anywhere with the identification of this bee, taken in early March at Bookham Common. As the Coltsfoot flowering season is not so far away, I'll be looking for this one again. Any guidance on possible identifications for the bee will be appreciated. Thanks.
