The colony in Hive H is dead.
There was clear evidence that the colony starved. There were no stores, and there were numerous bees inside empty cells. I saw evidence that they were still alive quite recently. I think that the recent spell of cold weather finished them off
I visited my out-apiary today and examined the removable hive floors for evidence of recent activity.
Three hives (D, F and G) show evidence of recent brood emergence. There were also hundreds of dead mites. Hive D had been especially prolific. There was also crystallised sugar which suggests that old honey is being eaten or cells are being cleaned out.
It's mid-October. The weather is supposed to be cooling but that's not what we're getting. Ex-Hurricane Ophelia is on its' way, bringing high winds and high temperatures. In Oxford we're forecast to get 40mph winds (fearties! fearties!) and 20C temperatures. The average October temperature is 10.1C (source: /node/191).
Hive H has settled in and has brood and stores.
It absconded in early August. I returned the colony to the same hive and then moved it to Headington. I put the frames to the front of the hive; fed them with Honey and made a very small entrance. This has encouraged them to produce brood and defend their entrance. I've seen lots of wasps around but none appear to have got in.
The 'swarm' which I caught two days ago turned out to be from Hive H. They had absconded from the hive leaving nothing behind - no bees; no brood; no stores - only a few wasps.
My out-apiary is under sustained attack from wasps.
There are dozens around the apiary. They concentrate their attention on the weakest hives. This has turned out to be hives F and H.
I caught a swarm today. It was small - perhaps about the size of an orange once it had clustered. It was stuck to the side of the building where my out-apiary is. I suppose that it came from one of my hives.
I boxed the swarm this afternoon and then moved it to the roof this evening.
The swarm is surely too small to survive the winter so I'm considering adding it to hive H, which is has too few bees.
I had a look into the hives in my out-apiary yesterday. There hasn't been much going on during July to comment on.
All the hives are showing activity. but either there isn't much nectar or they're working on brood production. All the usual pollen, Varroa and cappings which show brood activity. Very little new wax and generally little expansion in stores within the supers.
I think that there has been less nectar, or that the bees have had to travel further for it. Maybe they're expanding brood but I don't have evidence for that.
I moved Hive H from my garden to my out-apiary on Friday 30th June. I looked at the removable floor today and found 1 Varroa mite. Just 1 in 8 days. Compare that to Hive H which was dropping 20 per day as a new swarm.
The colony in Hive H has been feral for some time. The colony in Hive F had been a standard bought Buckfast queen 2 or 3 years ago. It's possible that the feral colony is adapting to Varroa and has managed to limit its' numbers. The mite is still present - it's endemic and won't now go away.
I'll see how Hive H fares as it settles in.
The bees which I've just collected as a swarm for hive H appear small compared to those from established hives. I've found it difficult to provide a photograph to show this. It was obvious when I caught the swarm: these were tiny bees. I've been wrong before so I decided to compare.
