What’s flowering now: early February

Everything is early this year. So we have snowdrops at the apiary:

It were a mild day today, so the allotment bees were out and about.

The plots were quiet except for birds hopping over the bare earth. The main crops in view were the strange shapes of brussel sprouts.

All is quiet with the bees at the moment, but before we know it spring will be underway and the first swarms will be here.

Thanks to Margaret Anne Adams, who posted helpful December 2015 advice from the Regional Bee Inspectors on the BBKA Facebook page: INSPECTORS_ ADVICE.docx – apparently there have been outbreaks of European Foulbrood (EFB) in the Shropshire/Welsh borders. Part of the advice given to prevent these outbreaks is to change brood combs regularly and avoid re-using combs from colonies which have died out. Now is a good time to prepare new frames ready for spring Bailey or shook-swarm comb changes.

Winter at last?

Last weekend brought a surprise – snowy rooftops. The white stuff melted fast, but the chilly air remained. Down at the apiary the ground was hard and all was quiet, with no bees flying.

Snowy roofs

When the bees are tucked up, the varroa boards provide a clue to the size and position of the cluster. The white flakes are particles of wax dropped by the bees as they uncap honey stores to feed. The dark brown oval shapes are varroa mites killed by oxalic acid trickling.

Varroa monitoring board

Each board tells a different story – some of the clusters are small and tight, others cover several frames. We have taken the boards out now as it’s not a good idea to leave them in all the time. This way the bees have ventilation at the bottom and plenty of insulation at the top, thanks to Tom’s specially built insulated roofs plus insulation foil from Wickes which we pack over the crown boards.

Varroa monitoring board

I checked the hive entrances and discovered that Melissa’s mouseguard had somehow come undone and fallen down on one side, leaving the entrance open. I put it back in place with extra drawing pins; hopefully I wasn’t trapping a mouse inside!

At this time of year I wish I could spend my winter huddling inside like the bees.  I don’t enjoy my winter commute – leaving for work and coming home from work in the dark, waiting at chilly bus stops.

Frolicking frost

The solution? A nice cup of tea. This lovely ‘Bee puffer mug‘ by Lush Designs was one of my Christmas pressies.

I can put my bee mug down on a bee coaster from Chickidee too, another lovely Christmas present. Finding bee-themed baby clothes is my next mission :)

New LASI oxalic acid research published

A comment by the lovely Amelia from afrenchgarden.wordpress.com on my last post led me to look at the University of Sussex’s Laboratory of Apiculture and Social Insects (LASI) website.

I was dismayed to see a new press release, ‘Scientists determine how to control parasite without harming bees‘, which advises beekeepers not to use the trickling or spraying oxalic acid method (which is what most beekeepers I know use). Instead sublimation (also known as vaporisation) is recommended.

“Professor Francis Ratnieks, head of LASI, says that beekeepers should cease using the other two methods (“trickling” and “spraying”, in which a solution of oxalic acid is used) as they are harmful to the bees and less effective at killing Varroa.”

Research accompanying the press release was due to be published today (Tuesday 5 January 2016) in the Journal of Apicultural Research, but unfortunately this journal is not publicly accessible to non-subscribers. I’ll try to see if I can access it through work as I would like to read the research study – it’s called ‘Towards integrated control of varroa: comparing application methods and doses of oxalic acid on the mortality of phoretic Varroa destructor mites and their honey bee hosts’ by Hasan Al Toufailia, Luciano Scandian and Francis Ratnieks.

The press release says the trickling and spraying methods “cause harm to bee colonies, resulting in reduced winter survival”. I wonder why harm is caused, how great the harm is, and whether it outweighs the harm caused by not treating for varroa at all. Emma and I have never had any colony losses following oxalic acid trickling and I cannot recall other beekeepers having experienced this either, but perhaps LASI have found colonies to be weakened by it afterwards.

Hopefully Beecraft and BBKA News will mention the study in their February issues.

An unusually warm winter for the bees

Happy New Year everyone! December here in London was unusually warm, with a high of 16°C (60.8°F) recorded at Kew Gardens. This has caused the bees to go through their stores faster than usual and also encouraged them to go foraging when they should really be tucked up inside conserving their energy. Back on the 19th December I needed my bee suit as so many bees were flying and even returning with two colours of pollen!

Fondant

Above is a hole one of our hives had made in their fondant. It’s lovely to put your hand on the plastic over the cluster and feel how warm it is. By the way they do also have plenty of honey stores, but they seem to like to go up to the top of the hive where it’s warm. Our colonies do this every winter.

Jonesy's fondant

Jonesy’s hive had eaten up all their fondant in under a month! You can also see that they’d even started building a bit of comb in the empty packet.

Winter drone

The warm autumn/winter has caused more drones to be around than usual – I spotted this live one on the roof of a hive. He was in good condition so must have been expelled recently.

Dead drones

Another hive had all these ex-drones stuck in the mouse guard. They looked recently dead.

Snowdrop tips, December

Snowdrops were peeking through the earth at the apiary a month earlier than usual and daffodils have been spotted in London. There are pros and cons to all this for the bees –

Pros

  • A warm winter allows the bees to raise more brood – useful if you want to get a spring honey crop
  • The bees can take more cleansing flights which helps with hive hygiene and makes disease outbreaks less likely

Cons

  • Risk of starvation increases if we don’t keep an eye on them
  • Less likely to be a brood break to help keep varroa numbers down
  • Warm weather encourages bees to fly even though not much forage is available
  • Brood raising and foraging will reduce the usual longer lifespan of winter bees

Any others I’ve missed? Or any you disagree with?

Northern England has been suffering floods, so I know I’m lucky to have only warm weather to worry about. One beekeeper posted on the BBKA Forum “having to do emergency beehive move tomorrow now I can get to the hives, due to flooding and a stream breach……too dangerous to try to get to them before and also had a cowshed 2ft under water to sort out with 30 cows in it, which had to take priority”.  Thirty cows to worry about on top of potentially water-logged bees, can you imagine? At 1.05 on this video you can see a brief clip about the effect the floods had on a York beekeeping business: UK floods.

Cat in a ball

If I could ask my cat Bob what weather he likes best, I think he’d go with warm and cosy please. Me too Bob, me too.

The things people want to know about bees

I’ve been looking back at the web searches people used to find my blog during 2015.

The most popular was ‘honeyflow’, with ‘honey flow’ and ‘honeyflow.com/commercial’ also in the top 10 (the last demonstrating that some people prefer to enter urls into search engines rather than their address bar). I wrote a post about the Flow hive back in February: Will the honey flow for you?. There were so many variations on Flow hive searches to find my blog that I should thank the inventors for sending all those visitors my way!

At number 6 was ‘braula coeca’, a now rare honey bee pest. I believe this is probably not because a lot of people are looking for information on it but because there’s not a lot of information out there. If you write about a niche subject, there’s more chance people will find your content. I wrote about this funny little jockey in 2013: Honey bee pests, diseases and poisoning revision post: Braula coeca: the ‘bee louse’

People are also trying to find out about chilled brood, stone brood and husbandry methods like shook-swarms and the Bailey comb change. I would always recommend going to the National Bee Unit’s Beebase website for expert bee disease and husbandry information you can trust: nationalbeeunit.com – especially their free advisory leaflets, training manuals and fact sheets.

Some of my favourites were the more obscure searches:

pile of dead bluebottles in an old building

paw print plum blossom on snow

has any one experience of meeting warm sweet honey – yep, tastes best eaten straight from the hive

how a university research garden should look like

someone who passed the exam has not read the book (wonder how well they did)

a honey bee habit – many of us do have a bee addiction

show me some lovely elsa cakes please

Well ok – cakes made this week by a friend of Elsa’s, she kindly brought them down to the apiary for us – they were so delicious:

Royal Jelly – a story by Roald Dahl

If you’ve ever read Roald Dahl’s short stories for adults, you’ll know they’re very different in tone to his more famous children’s books. My mum had both his Kiss Kiss and Switch Bitch collections and I re-read them quite a few times as a child, including the story Royal Jelly.

This week I was in the Barbican Library near my work and stopped to check out the returned shelves. One of the books there happened to be Kiss Kiss, so I got it out specially to read Royal Jelly again. As a child my knowledge of bees was basic, so the story had a new fascination now that I’m a beekeeper.

The plot involves a married couple who have just had a long-awaited child. The mother, Mabel Taylor, is “half dead with exhaustion”, out of her mind with worry because the baby girl will hardly take any milk. This baby is eating so little that at six weeks old she weighs two pounds less than she did at birth. Then an idea comes to Mabel’s husband, Albert. He is a professional beekeeper and whilst reading his beekeeping magazine comes across an article on royal jelly. The article details the wonderful properties of royal jelly, including the tremendous weight gain of a honey bee larva fed on it. ‘Aha’ thinks Albert – and proceeds to add royal jelly to his little girl’s feed. The strategy works, with the baby greedily lapping up this new formula and crying for more – but this new enriched milk also has some unexpected side-effects.

Reading the story now, I was surprised by how detailed and accurate Dahl’s descriptions of bee biology and beekeeping generally were. He must have done a fair amount of research to write the story. For instance, take the articles listed in the contents page from his bee journal: Among the Bees in May; Honey Cookery; Experience in the Control of Nosema; The Latest on Royal Jelly; This Week in the Apiary; The Healing Power of Propolis. The story was first published in 1959 and yet these could be articles from a current journal.

His descriptions of royal jelly were accurate according to scientific knowledge at the time. For example, Albert Taylor explains to his wife that it “can transform a plain dull-looking little worker bee with practically no sex organs at all into a great big beautiful fertile queen”. Worker larvae receive pure royal jelly for only the first three days of their lives, after which they are fed a mixture of royal jelly, honey and pollen. In contrast a larva chosen to become a queen receives only an abundance of royal jelly throughout her larval life, so much so that she is literally floating in it.

For years it has indeed been accepted opinion that royal jelly is the miracle food which has the ability to turn an ordinary female larva, laid from an identical egg to her sisters, into a queen. However, some new research published in August 2015 suggests that what really matters is what larvae chosen to become queens aren’t fed – the pollen and honey their ordinary worker sisters get. In 2008, Australian scientist Dr. Ryszard Maleszka managed to create queens in his lab without feeding them any royal jelly (by silencing a set of genes). One theory is that receiving no pollen provides chemical protection for the queen’s ovaries, as she is sheltered from the potential toxic or metabolic effects of plant chemicals.

All this is a rather round-about way of recommending this story to you and also mentioning that in April 2016 I’m expecting a little drone – just in time for swarm season. Having read the story, I will not be feeding him any royal jelly!

Tucking the bees in for winter

It has taken a while to come, but at last we have proper see-your-breath-in-the-air, see-the-sparkling-frost-in-the-mornings cold. The kind of cold that stops honey bees flying. I walked round the apiary yesterday and the hives could have been abandoned, so quiet were the entrances. Hiding inside – several thousand bees, hundreds of woodlice, a few gigantic spiders and at least one hibernating queen wasp.

Apiary in November sunshine

It is too cold for syrup now, so a slab of fondant has been placed over their crown-boards. Pepper’s girls also have one super, Melissa’s two. Peppermint’s bees were a new split from Pepper’s hive this year and didn’t manage to fill out a super, but they do have plenty of honey in their brood box.

Apiary in November

Mouse-guards are on, chicken wire to protect against woodpeckers has been placed around the hives and we are using special insulated roofs Tom made for us. Varroa boards left out so that the hives have ventilation from below through the open-mesh floors. I think of it as going into battle, assembling all the weapons we have against the elements and creatures that prey on bees. The bees will do most of the work of course, huddling protectively round their queen as outside the wind howls, the rain lashes and the frost bites.

Woodpecker chicken wire protection

These are a few last details but really preparing the bees for winter goes on all year long. You are always preparing the bees for winter – because the best weapon is having healthy bees to begin with. A combination of luck, the local environment and how well you looked after the bees during the year.

It’s things like how clean your equipment is, how recently you replaced your brood combs, how low you kept varroa levels, how much honey you left them, how many times you managed to inspect the colony without squashing the queen or tripping over and dropping boxes of bees everywhere. What was the weather like, were new queens able to mate well, could the foragers fly often, were there good sources of forage around for them to find? If all that went well, then the colony has a good chance of surviving whatever winter can throw at them. Just don’t forget to put your mouse-guard on.

What are your beekeeping weapons of choice against winter’s fury?
