I have heard that swarms can leave a scent and that swarms will go to the same site year after year. Is it possible this is different swarm
Hi Jimbo. If your marked queen is where you housed her this is another swarm. It's not that unusual. My father lets his bees swarm at will, ie, swarm control is new fangled mumbo jumbo, and about half of his (from 15 colonies ) land in the same mature Escallonia bush in the middle of his garden.

Did you jump on that trampoline and ping them up into a skep like something out of the Beano?

Onwards and upwards with the cupkit but I still say it is less of a faff to graft. Those look like good cells.
