Colony 01

Cleaning out after a harvest

Submitted by will on Mon, 20/08/2018 - 20:00

I harvested a super of honey from Colony 1 a couple of weeks ago. I also had some uncapped honey in frames which had been Hive C containing Colony 11 before I went through all the complicated rearrangements.

The conventional view is that the bees will thoroughly and carefully clean comb if you put it on their hive. In my wisdom I found an exception to this view.

Wasps everywhere but none appear to be getting inside

My hives are surrounded by at least half a dozen wasps which want to rob them. They zig-zag in front of the entrance; they crawl in under the Varroa screen; they wait at the edges and drink from the water tray. They want the honey but they can't get in.

All of the hives in central Oxford have small doors and strong guards. Three of the four have at least 20 bees visible on the outside of the hive entrance. One hive had fewer visible but appeared to be just as effective at guarding.

Anti-Ant (Part 1)

Colony 01 has an infestation of black Ants.

I find hundreds of them on the base board. I find very little pollen and no Varroa. I think that they harvest these. I don't know whether they're a serious pest but I would expect to find them throughout the hive. In any case, the base board is the place where I do most of my inspections so I need it to be intact. At the moment it's being reorganised by the Ants.

No crawling bees outside Hive A

For at least the last 2 years there have been flightless bees crawling around outside Hive A. These bees were clearly suffering from Deformed Wing Virus or another disabling virus. This year there are none.

The cause was explained to me by a researcher at University of Salford. All winter the Varroa mites feed from worker bees. They accumulate DWV virus particles. In spring, when brood production increases they rush in to infest the new brood and transfer more virus to them. These bees show visible signs of DWV -- deformed wings or an inability to fly.

Activity in all 7 hives

The colonies in all 7 hives are quiet this week. The weather is between freezing and 10C.

I checked the removable screens below the brood boxes. There appears to be activity in all the hives. I cleared away evidence of brood hatching from some of the hives but I don't think that I'll see much more hatching for a while.

Hive A appeared to be very quiet but the base board is frequented by ants and slugs. It's possible that they have been clearing away wax and sugar which drops from the hive. They don't remove the bodies of Varroa as far as I can see.

7 Hives at the end of the season

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.

The colour of honey

I recently took some honey from Hive A. Most came out as comb but there were also a couple of jars.

Yesterday I returned to Hive A. Some time ago I had put some broken comb pieces onto the crown board. In the usual way the bees had built a large slab of comb around it it and started to fill it. I cleaned up the crown board and then hung the crunched comb in mesh bag overnight.

Small bees, or, the vicissitudes of photography

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.
