Last night I went to visit my out apiary. As I was pottering around I received a phone call. It's hard to answer when your phone is inside a bee suit.
The call was from the same people who had given me the colony in Hive E. I'd given them some honey and asked for them to call when the feral colony swarmed.
I arrived to find a football sized cluster on their apple tree. They say it's the first swarm of the season - prime swarm.
