Colony 11 is complicated. I may have just made it better, or worse.

The colony was probably evicted from a roof in the Grandpont area of Oxford by building work. A member of my bee group said that the colony was too aggressive for a domestic garden so I gladly took them. They arrived in a nucleus box which had no frames.

I peeked at Colony 13 inside Hive H. There is nothing there: no comb and no cluster of bees.

I was uncertain whether there was a Queen after I'd found a dead Queen in the swarm box. I had put on a feeder on to stimulate them but I'd seen robbing in progress from Colony 11. It appears that robbing is all that's going on.

I don't know what has happened to the bees which I put into the hive. They may have dispersed to the other colonies on the roof.

When the feeder is completely empty I'll be able to see what is left.

Colony 13 is dropping Varroa. They are also cleaning out old comb so there is a lot of debris on the hive floor. I found 2 or maybe 3 Varroa bodies.

This colony is new to my apiary, having been established elsewhere. I haven't really included it in my Varroa Zero post because it's new. Hives D and G are included. There were no Varroa on the floor of either this morning. There doesn't appear to much activity in Hive D at all. I shall have to check them.
