This is clearly a worker and not a cuckoo bee (e.g. B. vestalis; B. barbutellus). I am tempted to exclude B. hortorum, as the face does not appear long enough and the flower, ground elder, isn’t obviously deep. Of the “Big Six”, that leaves B. terrestris and B. lucorum. B. cryptarum has been mentioned to me as another candidate but I am not sure if I have a good enough angle on the yellow collar to decide on that here.
