HARVEST!

Each hive has produced one super (ten frames) of surplus honey this year, and I've been waiting for the right time to take them off the hives.  Last weekend was fairly dry, weather-wise, so I figured it was probably my best chance to get harvest done.

This year, I needed to be extra-careful with hygiene arrangements because of COVID-19 so as well the the usual tasks of thoroughly cleaning down the utility room and laundering the aprons and hats, we also wore clean masks throughout to minimise any transmission risk.  I'm also going to quarantine the sealed jars for 14 days, just to be sure that neither of us were infected when we did the extraction.

Mrs Beekeeper was on hand to uncap the combs, while I worked the extractor.  Here's a couple of action shots of us hard at work:

The final haul is 7 jars from Athene's hive and 9 jars from Ottoline's bees.  Not my best year ever, but at least it will be enough for a few stocking fillers at Christmas.  And it's always satisfying to have a little reward at the end of the season.

Bees On The Move

Earlier this year I was speaking with local bee enthusiast Joel, who has a big garden in Southdown.  Joel was keen to have some bees in his garden, and we’ve been discussing the best way to make that happen.  So, a couple of weekends ago I went over to do a site survey.

The garden has a hazel thicket at the north end, which should work well to keep the bees separate from the rest of the garden.  So, to get things started, we’ve agreed to move the nucleus into a small clearing by the hazel so Joel and his family can see how they get on with them.

Last Saturday was moving day. so I waited until dusk (bees need to be moved after sunset), closed up the entrance block, applied liberal quantities of duct tape, and secured the nucleus with a ratchet strap:

Then I carried the nuc to the car, and hit my first snag - if I put it in the boot, there was too much space either side and it was likely to wobble, and probably fall over, once I started moving.  So I ended up wedging it - very carefully - into the passenger footwell, and then set off on the short drive up to Joel's garden.

Joel and his family greeted me at the other end, eager to see the box of bees arriving.  It was dark by this point, but fortunately Joel was better prepared that I was, and had a couple of head torches and a wheelbarrow standing by.  We wheeled the nucleus to the other end of the garden, and placed it in the new spot that I'd prepared.  Then, everybody else stood well back while I opened the entrance block.  The bees were surprisingly well behaved (I always expect them to be in a bit of a mood after a trip in the car).  A couple of guard bees flew out to let me know I wasn't welcome, but the others were happy enough staying inside until morning.

The next day, Joel was feeling brave enough to check out the front of the hive and sent me this photo:

Not much happening there, though he did update me later in the day to let me know that a lot more bees had started flying in and out, and checking out their new surroundings!  So far, they seem to be settling in well, and - apart from maybe feeding them a few pints of sugar syrup - I can pretty much leave them alone until the spring.

As for the hives... well, it's very nearly harvest...

Introducing... Queen Athene!

Every beehive has a single queen bee, and the queen in hive #1 is called Athene. She is named after Professor Dame Athene Donald, who is a physicist, Professor of Experimental Physics at the University of Cambridge, and Master of Churchill College, Cambridge.

Athene read physics at Girton College, Cambridge, gaining her PhD in 1977 for research into electron microscopy of grain boundary embrittled systems.  She then moved to Cornell University working as a postdoctoral associate on research into metals.

In 1981 Athene returned to Cambridge, and took up a post in Cambridge's Cavendish Laboratory in 1983.  In 1988 she became Professor of Experimental Physics, and in 2014 became Master of Churchill College.  She was elected a Fellow of the Royal Society in 1999.

Athene's area of research specialism is in soft matter physics, and this includes the study of soft matter in living organisms as well as organic substances such as starch and proteins.  This developed from her earlier work on polymers, and includes the study of organic polymers using electron microscopy and X-ray scattering.  Her research has included structural changes to biological polymers when cooked, and amyloid folding of proteins.

Athene has been and continues to be actively involved in the promotion and encouragement of women in science.  She was director of WiSETI, Cambridge University's Women in Science, Engineering and Technology Initiative, from 2006 to 2014, and the University's Gender Equality Champion from 2010 to 2014.  She also chaired the Athena Forum - an organisation committed to the advancement of women in science in UK higher education - from 2009 to 2013.  She has served on the Gender Balance Working Group of the European Research Council, and is a Patron of the Daphne Jackson Trust.

Athene is also an advocate for interdisciplinary research, and was the founding chair of the Institute of Physics Biological Physics Group from 2006 to 2010.  She has served as a member of the Science Museum Advisory Board, and is currently chair of the Interdisciplinary Research Advisory Panel for the 2021 Research Excellence Framework.

Here is a photograph of her namesake, queen Athene:

New Queen!

Two weekends ago, I opened up hive #1, to check on the queen cell.  This is what I saw:

That is excellent - a textbook emerged queen cell.  It still amuses me that, when the queen nibbles the end off the cell, she doesn't remove it completely, but leaves a small 'hinge' on the lid.

Anyway, I didn't see the queen that day, and had to wait another week to see if I could spot her.  Which brings me to Sunday, when I opened the hive again and, after a little bit of peering about, saw this:

Yes, that is indeed the new queen!  If you didn't spot her, I promise she definitely is in the photo.  She's actually the one that is less stripy than all the worker bees.  So, think of it as a game of "Where's Waldo?" - except in this version, everyone is wearing a striped top except Waldo.

She's not laying yet - probably because the weather hasn't been great, so she hasn't had a chance to fully mate yet.  Hopefully that will all change by the weekend, and then I'll be able to mark her and name her.

Hive Swap

For a while now, June's bees in hive #2 have been a bit of a handful.  Even though I'm pretty careful when I handle them, they've been more defensive than hive #1, and they sting me fairly regularly.  Also, they have stung their landlord Nev at least once (and tried several times).  So I decided that something needed to be done.

The best option I could come up with was to swap the colony with Ottoline's bees in the nucleus.  They are very well behaved, calm, and I don't think they've stung me at all.  Normally, this would be straightforward - just pick up each hive and swap them over.  However, I'd have then ended up with the nuc where a hive should be, and it would have messed with the aesthetics of the apiary.  Which are... y'know... the most important thing.

So, I was going to have to do it the hard way.  I suited up, lit my smoker, and got ready to move the colonies frame-by-frame.  In fairness, it went pretty smoothly.  The bees were pretty well behaved throughout, and I only got one sting.

Over in hive #1, I had a look to see if they’d made any queen cells to replace Katherine (RIP).  Indeed they had - all these and more, in fact:

Here are all the cells I cut out from all the combs:

I’ve tried to arrange them in order of age from left to right, so if you look carefully (you’ll need to click on the photo to zoom) you should see the ones on the left look more ‘maggoty’, whereas you can see the ones on the right starting to differentiate into their adult segments.

I left one cell in the hive - pictured below - this will (when she hatches) become the new queen of hive #1:

I’ll take a look this coming weekend to make sure that the new queen is alive and well.

An Accident - Or Something More Sinister?

I checked the bees on Saturday, and everything in the nucleus (Ottoline's bees) was fine.  All good in June's hive (#2) as well.

Things in Katherine's hive also looked fine - at least, at first.  There were recently-laid eggs, as well as capped and un-capped brood.  A few frames in, and I found an open queen cell, which I removed.  On the next frame were four more.  I tackled the first three, removing the small larvae and cutting out the structure of the cells to discourage the bees from re-using them.

When I got to the 4th queen cell, I noticed something odd.  Instead of the end being completely open, there was a dark shape just poking through the entrance.  At first, I thought this would be a worker bee, depositing royal jelly in the cell for the larval queen to feed on.  But, oddly, it didn't seem to be moving.  Also, it didn't look like the end of a worker bee - it didn't seem stripy enough, and it was too pointy.  I carefully cut away at the sides of the queen cell, and was amazed to pull out this:

Yep - that's Queen Katherine - dead, after being stuck head-first in a queen cell.  This is a picture showing where it was located on the frame (you can clearly see it in the corner, towards the lower part of the photo):

And here's a closer look (you can even still see specks of green paint that have rubbed off from her thorax):

This is really remarkable - it's the first time I've found a dead queen inside a hive (though I have previously seen a dead queen outside, after she was dumped there by her workers).  And the really weird thing is, it seemed from the shape of the cell - the entrance of which seemed too narrow for her to squeeze into - that the workers were sealing her in, from the outside.  This is genuinely odd - I've never seen or heard of bees behaving like this before.

So, what had happened?  Well, there are two possibilities:

1. She'd for some reason crawled into the queen cell head-first, and got stuck
   
2. The workers chased her into the cell, and killed her

Looking at option [1], it's not by any means impossible.  But it is unlikely.  A queen will always enter a queen cell abdomen-first, as she has only one business being there - to lay an egg.  She has no reason to go in head-first if the cell is empty.  And if there is already a larva in there, with royal jelly, then there's no point going in head-first either (she can't feed the larva - that's strictly a worker bee job - and she can't eat the royal jelly, as she has to be fed mouth-to-mouth by the workers).  But maybe it was a freak accident?

Or maybe not.  After all, she had laid eggs within the last day or so (I know - I saw them).  So why was she dead?  She could, perhaps, have got stuck and died - but I'm not sure there would have been enough time for her to have starved to death.  Maybe, then, she had been stung to death by the workers, who for some reason had decided to replace her.  If you look at the photo of her (click on it to see it in higher-resolution) you'll notice her wings have been damaged.  Now, that might have happened when I was getting her out of the cell.  But I suspect they may have been bitten by the workers when they attacked her.

Like inside a beehive is pretty brutal - if the workers decide the queen is not meeting their high standards, then they will cheerfully kill her off and replace her with one of their sisters.  I've had this happen a couple of times before - it's just a part of beekeeping life that you get used to.  But never before have I found the queen's body still inside the hive.  I've been keeping bees for 10 years now, and yet every season they still manage to surprise me!

In case you're wondering how the bees will cope without a queen - don't worry.  Right now, they will be making new queen cells (from the eggs I saw), and I will have a look in the hive tomorrow to see how they are getting on with raising Katherine's replacement.

Introducing... Queen June!

Every beehive has a single queen bee, and the queen in hive #2 is called June. She is named after June Almeida, who was a Scottish virologist, and a pioneer in virus imaging, identification, and diagnosis.

June started her career working in histopathology at the Glasgow Royal Infirmary, and then moved to St Bartholomew's Hospital in London.  In 1954 she moved to the Ontario Cancer Institute, where she worked as an electron microscopy technician.  While in Ontario she was awarded Doctor of Science (Sc.D.) for electron micrographic research of antibodies.

In 1964 June joined the research team at St Thomas's Hospital Medical School in London.  She worked on the hepatitis B virus and also cold viruses, as well as a new virus in humans that at the time was given the identifier B814.  June used electron microscopy to photograph organ cultures containing B814, and noticed that the structure of the virus particles was similar to two other viruses she had previously studied - infectious bronchitis of chickens, and mouse hepatitis liver inflammation.  Her previous papers on the chicken and mouse viruses had been rejected by reviewers, who believed that the viruses were actually known flu viruses.  However, with the evidence from B814, June now knew that she was looking at a new, and previously unidentified group of viruses.

June's photographs of the new viruses showed that they appeared to be surrounded by a distinctive 'halo' - caused by protein spikes on the surface of the virus.  The latin for 'halo' is 'corona', and so this family of viruses became known as 'coronaviruses'.

As well as her work on coronaviruses, June also continued to work on hepatitis B, and in the 1980s she was involved in producing micrographs of the HIV virus.  Later in her career she worked at the Wellcome Institue, and in retirement she maintained an advisory role at St Thomas's Hospital Medical School.
