We've got a nest of the white tailed bees in one of our compost bins. They're loving the nearby roses, irises and nepeta. It's not very convenient for us, as we can't evict them until the autumn apparently and we have to run the gauntlet up to the shed. Does anybody know exactly what they do - I'm presuming it's not honey production? Why are some twice the size of the others?
