Thanks for the ID Murdo - but I would love to know how you tell the difference between sexes
All bumble males have 13 antennal segments, females 12. Females (non-cuckoo) have a pollen basket. And males don't sting, so if you pick one up and it stings, it is female. However, with years of practice they just look male or female. With this species it is easy - females are all black except for the tail, males have the yellow, sometimes much more than this. But then you have to know that you are looking at lapidarius, and not pratorum or monticola. Anyone who told you bumbles were easy was having you on!
