White tailed bumblebee - part of the B. terrestris group so workers are usually not distinguishable in the field, and queens only sometimes, but males are, at least up to the Bombus lucorum complex.
The Lucorum complex includes B. lucorum, B. magnus and B. cryptarum, there are some minor differences between queens, but workers and males are each only distinguishable using further testing (like the composition of male pheromones, or mitochondrial DNA testing). Really entry level bees as you can see 🤪
Tagging and keeping ID as B. lucorum because that's most probable in this case !
