Host parasite relationships can end in one of only three ways: extinction for either or in a balance between the two. The most likely outcome is surely to find a balance.
Paul visited my out apiary. I needed an experienced view of what was going on. He has Warre hives and so was interested in the site and the hives.
The inspection went well until near the end.
Hive B was still small but there was fresh brood, showing that their supersedure had been successful. They had formed a neat sphere of comb, more obvious because it was foundationless. They'll go into winter with sufficient stores but in need of insulation.
I was called today to collect a late swarm from Barton. The woman who called me says that it is the 5th swarm this season to leave a nearby feral colony.
The feral colony is living in an air brick in a house about 30m from the apple tree where the swarm was clustered. The swarm emerged on Friday. Today is Tuesday. She'd expected them to disperse but there they were.
Collection was simple. Shake them from a branch at head height into a nucleus box. Leave for 5-10 minutes. Thank everyone and remove.
