Coffee, constancy and fidelity

Synopsis : Why do bees collect pollen of only one type when foraging? Why do they forage repeatedly in the same area? What has coffee got to do with this?

Introduction

Foraging is what my bees should be doing now. The summer nectar flow should be strong – lime, blackberry, rosebay willow herb (RBWH, fireweed) then heather – it’s bonanza time.

But note the qualifier ’should’.

So far, it’s not looking promising.

The lime was hopeless, the blackberry flowered well but doesn’t appear to have yielded much, the fireweed is nearly over (early) and the heather … well, let’s not prejudge anything, but I’m not hopeful.

Going, going, gone … rosebay willow herb, mid-July 2023

Not only do those four plants/trees yield nectar, but they also produce pollen and you can often tell what the bees are foraging on by the colour of the packed corbiculae on the hind legs of returning workers.

Despite their overlapping flowering periods the pollen baskets are almost always a single colour. For example, you don’t get deep purple pollen baskets from RBWH speckled with much paler borage pollen, despite the fact you can find both flowering – in a field and its margins – simultaneously.

This is because honey bees tend to forage on one plant species 1 on any foraging trip. This feature of the foraging habit of honey bees is termed constancy.

If you marked a foraging worker on a patch of RBWH, watched it fly off to the hive and waited a bit you might well see the marked bee return to the same patch of RBWH and start collecting pollen or nectar again.

This is not constancy but is instead termed fidelity.

Both fidelity and constancy have consequences for plant pollination. It’s therefore unsurprising to discover that some plants have evolved to influence these foraging habits of bees … which is where the coffee comes in.

Scores on the doors

Conveniently, this final post of the year will be published on the final day of the year. This is an appropriate time to look back over the what’s happened here on The Apiarist … a sort of behind the scenes view of the posts that were popular, the posts that were unloved and the creative writing process that converts a title and a topic on a Tuesday to a perfectly honed essay garbled jumble of words on a Friday.

Precisely because the final post of the year appears on the last day of the year, any stats I mention below will exclude this post. Should 15,000 people read this post late on New Year’s Eve 1 then this page would also make it into the ‘Top of the Posts’ lists.

Hives in the snow

And, in between some of the numbers and comments below there’s likely to be a smattering of beekeeping advice or unanswered questions, just to keep you on your toes.

So … without further ado.

Read all about it

Page views, visitor numbers, those registered for email notifications etc. are all higher this year than last, by ~30%.

Going up … page views and visitor numbers graph since time began

New posts appear on Friday afternoon around 3 pm 2 and tend to get the most views on Friday evening and over the weekend, tailing off through the remainder of the week.

Some posts are then rarely read again. Others go from strength to strength, attracting readers in successive months and years. This longevity depends upon a combination of subject matter and ‘fit’ with current search engine algorithms.

Regular as clockwork

Inevitably, the popular posts are often those on ‘how to’ subjects. Perhaps unsurprisingly, considering this is a beekeeping site, the top posts of the year were all on either swarm control or Varroa management.

Top of the posts

These were the most read posts of the year. Tellingly, only the one in bold first appeared this year:

  1. Queen cells … don’t panic! – a title designed to attract the beginner who, having discovered their first queen cells, is now busy panicking.
  2. The nucleus method – my favoured method of swarm control. Almost idiot proof, this explains why it’s my favoured method of swarm control.
  3. Demaree swarm control – a little bit of history and another swarm control method. What’s not to like?
  4. When to treat – a post that first appeared almost 5 years ago. Most of the relevant information is now included in other posts, or summarised in the more recent – and therefore recommended – Rational Varroa control.
  5. Vertical splits and making increase – another ageing post that, by combining swarm control, making increase, requeening and running out of equipment, has something for everyone. I think this could do with updating and deconvoluting.
  6. Swarm control and elusive queens – a useful method for those who struggle to find queens. More important still is that, for beginners, if they understand WHY it works then they’re well on their way to becoming a beekeeper.
  7. Honey pricing – higher, higher! There’s loads of cheap ‘honey’ flooding the market. You are not competing with it. You have a premium product. Do NOT sell your honey cheaply.
  8. Swarm prevention – something that should have been read before items 1, 2, 3, 5 and 6 in this list … but possibly wasn’t considering it was read fewer times 🙁 3
  9. Pagden’s artificial swarm – the most popular method used by beekeeping associations to completely confuse beginners (see the nucleus method above for an alternative).
  10. Oxalic acid (Api Bioxal) preparation – which is currently the most read post, proving conclusively to me that many more beekeepers need to read Rational Varroa control because many colonies will now be rearing brood (see the photo below).

Together, these 10 posts counted for about 20% of the total traffic this year. The remainder were smeared over the other 448 posts that have appeared since early 2013. 

Biscuit-coloured crumbs on the Varroa tray = brood rearing. 23rd December 2021, Ardnamurchan, Scotland

If you’ve got some spare time, show some love for Seasonal changes which only received a single visitor this year. The late September 2016 post contains a nice picture of an orchid and a bottle of honey beer.

Search and ye shall find

The majority of visitors arrive either in response to the weekly emails announcing new posts 4 or from search engine searches. The latter are nominally a valuable resource, so are not disclosed to those of us who actually write the stuff in the first place (unless we pay Google).

However, the 0.5% of searches that come from other search engines turn up a few interesting terms (my selection from hundreds, and in no particular order):

  • cbpv winter – not usually associated together as this is a virus (chronic bee paralysis virus) that usually damages very strong, crowded hives in the middle of the season.
  • diy Kenyan beehive – not something I’ve ever discussed 5 or know anything about 6.
  • how much income from beekeeping – just a bit less than not enough, but fractionally more than SFA.
  • pointers to successful queen introduction (2006) bickerstaffes honey – a really rather specific search. I wonder whether this site was any help?
  • bee hive in old norse – see ‘diy Kenyan beehives’ above, the same sentiments apply.
  • Как сделать станок для натягивания проволоки на рамки для ульев чертежи – that’s easy … you need one of these.
  • maldives beekeeper – I have one photo on the site from the Maldives which I suspect resulted in this ‘hit’. I hope the reader wasn’t disappointed 7.
  • does a virus make bees angry – actually not such a daft question. There’s a Japanese strain of Deformed wing virus called Kakugo which is supposed to cause aggression. Kakugo means readiness or preparedness.

And, of crsuoe, there wree hrdudens of saehrces wtih snlpileg errors. Mabye smoe brepkeeees olny serach for initofrmaon atfer benig stnug rltedepaey on tiehr fenirgs? 8

Some of the spelling errors were so gross that the resulting word was barely recognisable.

There were also about 8 different spellings for ‘apiarist’ … not bad for an 8 letter word 😉

Prolixity

Fifty two posts have appeared in 2021, each averaging 2,675 words. This is an increase of about 8% over the 2020 figures 9. In total, excluding the ~1200 comments, that’s about 139,000 words.

Tolstoy’s War and Peace … more words, more characters, less bees

For comparison, this is a bit under 25% the length of War and Peace.

Phew!

Talking the talk

As well as writing too much (it has been said that) I talk too much. During 2021 I’ve given 25 talks to beekeeping associations stretching from Cornwall to Inverness 10. Audiences have ranged from about 15 to 350 and I’m very grateful to all the BKA’s who hosted me and coordinated the Q&A sessions.

Particular thanks to the associations that managed to send me the Zoom link for my presentation before the talk was supposed to start 😉 .

Although the talks were all ‘virtual’ it was good to see some old friends and to make new contacts.

Spam, spam, spam

Of the ~1200 comments I mentioned above, many are from me. I try to respond to every comment, irrespective of whether they are corrections (for which many thanks), additional insights (thanks again) or further questions 11.

Running a website, even a relatively low traffic one such as this, means you receive a lot of spam. ‘A lot’ means usually between 200 and 800 comments or emails a day. To avoid the comments section getting tainted with adverts for fake sunglasses or dodgy prescription drugs 12 I manually ‘approve’ every comment that appears.

Spam

This isn’t as onerous as it sounds. I run spam filters that trap the vast majority of the unwanted spam.

This filtering is not 100% accurate … if you previously posted a comment and it never appeared then it may have fallen foul of these filters. Next time avoid mentioning that you were wearing Ray-Ban sunglasses when you inspected the colony 😉

It’s a rather sad indictment of the internet that I sometimes receive the same amount of spam in one day as I receive in valid comments in one year 🙁

You’ve got mail

The comments and questions – whether to posts or talks – are often very interesting. After all, I may have delivered the same talk three times in the last month, but the questions will always be different. I’ve touched on this previously in Questions & Answers.

Some questions are direct, relevant and on-topic. These are usually easy to understand and answer, though they may not be easy to answer correctly.

But there two other types of question:

  • Rambling, incoherent and vague … almost always lacking some essential information, like location. These often start with a detailed description of the last three colony inspections and end with something about Nosema or polycarbonate crownboards. There may not even be a question mark …
  • Direct – verging on blunt – and totally off-topic. It’s not unusual to prepare 2,500 carefully crafted 13 words on rational Varroa control to then receive the question ”What is the recipe for thick syrup?”.

In addition to comments/questions to posts and talks I receive a lot of email. If you emailed me this year and I failed to answer promptly then it’s probably because there were 50 other unanswered emails I’d yet to wade through.

With the volume becoming unmanageable I’ve started ignoring the very terse emails requesting a quick response (because the sender is ‘busy’ and wants the answer before they leave for the apiary/office/school run/anger management class) like “What is the recipe for thick syrup”.

The few who send adverts for their quack solutions to Varroa (often vaguely disguised as informed questions) or abuse – you’d be surprised, I was – are both ignored and blocked.

Life is too short …

New topics and old chestnuts

Beekeeping is a fantastically diverse activity 14. From the single hive owner to huge commercial operations, from the hive-monitoring techno-geeks to the leave-alone organic types, from honey to venom … there really is something for everyone.

It’s therefore no surprise that there is never a shortage of topics to cover. This is particularly true when you also include some of the wonderful 15 science of honey bees.

Web of Science publications on “honey bees” since 1997

I’ve covered some beekeeping topics exhaustively and get little satisfaction from re-writing the same thing differently 16. However, these are the topics that often attract the most readers – presumably many of whom are new beekeepers.

I’m not too fussed about the reader numbers, but if I’m going to go to the trouble of writing something I do want it to be read 17.

I’m currently wondering about how to achieve a balance between what might be considered the ‘basics’ and some of the more advanced – and to me (after a lot of beekeeping) much more interesting – topics.

And I’m always happy to consider new topics if you think I’ve missed something 18.

The writing process

I usually accumulate ideas on long car journeys, while walking in the hills, out on the loch or during interminable meetings. They might start as little more than a title and a reference, or a sentence of text.

Seeking inspiration for new articles for The Apiarist

I rarely have anything actually written by the weekend before the post appears, though I will usually have decided on the topic.

This post is being written on a Tuesday, but late – often very late – on a Thursday is more typical.

Two to four hours is usually sufficient for most posts, though additional time is needed if there are custom figures or graphs.

It’s very useful to then leave the draft for a few hours after ‘finishing’ it.

I usually abandon the keyboard by 2 am on Friday and look again first thing the following morning. Typos are caught, my awful punctuation is largely fixed and some of the more garbled sentences are rewritten in English 19.

And then I press ‘Submit’.

Flat white, cappuccino, ristretto, latte macchiato and affogato

And all of those activities – the thinking, the writing and the proof-reading – are fuelled by a delicious and fulfilling combination of strong coffee and pizza.

I’d therefore like to again thank the supporters who have ‘Bought Me a Coffee’ during 2021. In particular I’d like to acknowledge the repeat supporters. In addition to facilitating my nocturnal writing marathons, this support has also enabled moving the site to a more powerful (and properly backed up and appreciably more expensive) server.

Thank you

The future

I’m looking forward to the year ahead for many reasons. I expect 20 to have a lot more time for my bees and beekeeping. In the meantime, I’ll probably write about some of my immediate plans in the next week or two.

Winter-flowering gorse, December 2021

The size and complexity of this website – hundreds of posts and thousands of images – is starting to make it both difficult and time-consuming to maintain. It’s a dynamic site, the pages being generated on the fly when your web browser requests them. There’s a significant performance cost to retaining these dynamic features, and the underlying software is bloated and a target for hackers.

I’m therefore considering alternatives that make my life a little easier and your browsing experience a little faster. One way to achieve this is to use what is termed a static site. Anyone who has looked up details of my online talks (which has ~16 images and ~2500 words, so broadly comparable to a Friday post) will have used one of these. This technology is becoming increasingly common for blogs. I still need to resolve how to retain the comments/discussion features.

I’m also keen to explore some more expansive topics.

Even ~2500 (or more) words is insufficient to do some subjects justice; the impact of honey bees/beekeeping on solitary bees and other pollinators, neonicotinoids, fake honey, the prospects for Varroa-resistant bees, more advanced methods of queen rearing etc.

Real honey … not the product of unspecified EU and non-EU countries

How do I tackle these?

Should I write less and not explore the subject fully?

Write in instalments?

Or just not bother?

What do you think?

And while you ponder that and some of the other points raised above I’m going to enjoy the last few hours of 2021 and close by wishing all readers of, and contributors to, this site the Very Best for 2022.

May your supers be heavy, your queens fecund, your bees well-tempered and your swarms … from someone else 😉

Happy New Year


Notes

The phrase [the] Scores on the doors originated from the panel show The Generation Game hosted by Larry Grayson between 1978 and 1982. However, it was subsequently appropriated to indicate the public display of food hygiene ratings.

If you arrived here from @Twitter then you might be wondering what omphaloskepsis is. It means navel-gazing as an aid to meditation. Readers with a classical education will recognise its derivation from the Ancient Greek for navel and contemplation. Scrabble players will be disappointed it doesn’t contain more high scoring consonants.

In the bleak midwinter

Winter has finally arrived.

Green thoughts in a white shade

We’ve had temperatures fluctuating around 0°C for the last two to three weeks now, with some very hard frosts and more than enough snow to make the track impassable.

Like the bees, I’ve spent the time hunkered down focusing on keeping warm and conserving my stores.

Unlike my bees, I’ve benefited from triple glazing and a wood burning stove 😉

And the main thing I’m worried about running out of is milk for my cappuccino 1.

The 20th was particularly cold with temperatures well below -5°C and stunningly clear. There was something strange about the conditions, as the loch froze. The surface, for 30 metres or more from the shore, had a thin film of ice covering it.

Ice, ice baby

As the tide dropped the shore was left with a sparkling crust of 1mm thick glass-like ice confetti.

The salinity of seawater is typically ~3.5% … this amount of salt reduces the freezing point to about -2°C, a temperature we’ve regularly experienced in the last fortnight. This suggests the ‘strange’ conditions were probably the absence of any swell coupled with the really calm conditions.

Whatever the cause, it was beautiful.

Early season forage … you must be joking 😉

Under conditions like these the bees are effectively invisible. They’re very tightly clustered . With daytime temperatures rarely reaching 3°C none venture out of the hive. With the exception of cleansing flights and the removal of corpses – and it’s too cold for either of these – there’s little reason for them to leave the hive anyway.

The gorse is in flower … somewhere under there

The only thing flowering is gorse and it would be a foolhardy bee that attempted to collect pollen at the moment.

I’ve previously written about the genetically-determined flowering time of gorse. In an attempt to improve forage at certain times of the year I’ve been collecting seed from suitable plants and germinating it indoors. As soon as the weather improves I’ll plant these seedlings out 2 as the amount of gorse around the apiary is quite limited.

Gorse (and some broom) seedlings

Gorse seed is painful to collect and germinates poorly. I pour boiling water over the seed and then let it soak for 24 hours, which improves germination at least ten-fold.

Hive checks

Every fortnight or so I check the hive weights by hefting. Only two colonies have had any extra fondant yet and that was through ‘an abundance of caution’. I suspect they actually didn’t really need it.

The next eight weeks (here 3 ) is when brood rearing should be starting to really ramp up. It’s during February and March that starvation is an issue.

Here on the west coast, my colonies are rearing brood. This tray has been in for about a week. I’m including it as I’ve been asked several times about how to determine if a colony is rearing brood without opening the hive.

Biscuit coloured (or a bit darker) cappings indicating brood rearing in this colony

The red arrows indicate the biscuit coloured cappings that have fallen from the seams in which they are rearing brood. The inset shows a magnification of the indicated part of the image. The photo was taken with a camera phone and the cappings are perhaps a bit darker than usual (though I also know there are a few older brood frames in this hive 🙁 ).

And if the conditions are right, even with a well-insulated poly hive, you can identify which wall the cluster is up against by the evaporation of the overnight damp from the outer surface of the hive.

The location of the cluster is clearly visible on this Abelo poly hive

This is the front of the same hive from which the Varroa tray was photographed – the cappings on the tray and the cluster location correspond perfectly.

By the way … don’t bother looking for Varroa on the tray. This hive is in a Varroa-free region 🙂

As I’ve said before, it’s not unusual for colonies in poly hives to cluster tightly against the wall in winter. Those in cedar are more often away from the wall in my experience (and the same thing applies to brood rearing other than at the height of the season).

Hey good lookin’

The Abelo hive above is a nice looking box. The paint finish is bonded well to the polystyrene and provides good protection.

If you leave unpainted polystyrene out in the elements it starts to look pretty tired, pretty quickly.

I don’t have any pictures as none of my poly hives are unpainted.

At least, none are any more 😉

I’d acquired some new Maisemores nucs with bees and had a number of unused and unpainted Everynucs. Most manufacturers recommend you paint poly hives with masonry paint of some kind, or they sell (often quite pricey) paint that’s suitable.

Here's three I prepared earlier ...

Everynuc poly nucs

I’ve painted a lot of nucs with masonry paint, using a paint spray gun. It goes on fast and is reasonably hardwearing … but not great.

Swienty brood box ...

Swienty brood box …

In contrast, my Swienty brood boxes look as good now as when they were first painted 5 years ago. These received two coats of ‘Buckingham green’ Hammerite Garage Door paint.

This paint is designed for galvanised metal garage doors (the clue is in the name 😉 ). It contains a bunch of unpleasant sounding solvents but, when dry, appears to be entirely safe. I’d recommend not reading the 13 pages of safety data sheets or you might never dare open the tin because of the imminent risk of explosion.

Melting polystyrene

These solvents have the effect of slightly ‘melting’ the surface of the poly hive. This creates a really strong bond between the paint and the hive surface. The melting isn’t enough that you can notice the surface texture change … it’s just an invisible chemical reaction going on as you brush the stuff on.

Maisemore’s poly nuc after the first coat

However, this reaction might account for the rather patchy coverage of a single coat. If you paint it on thickly enough to try and produce a nice even finish it tends to run and sag a bit.

So give it two coats … and then it looks excellent.

Oxbridge Blues – a few painted poly nucs ready for the season ahead

Several months ago I bought a ‘remaindered’ tin of Hammerite paint in Oxford blue. I had wanted a contrasting colour (to my other boxes) for these nucs to help orientate returning freshly mated queens.

I paint the entire box, avoiding any of the ‘touching’ faces which are left unpainted. Some paint usually seeps into joins between the roof, body and/or floor, but you can easily prise them apart with a judiciously applied hive tool.

I’m rather pleased with how smart they now look.

I’m somewhat less pleased with the quality control on some of the Everynucs 4. Several had the mesh floor stuck down incorrectly, with parts unattached. In places the gaps were big enough for a bee to enter.

Open mesh floor and big gap at the side in an Everynuc

I simply pulled them off and restuck them down with a glue gun. This is an easy fix but really should not be necessary on a nuc box that costs almost £60 🙁

A+E

With the current Covid pandemic we have a responsibility to minimise the demands we are placing on our heroically overstretched healthcare workers.

For this reason I’ve been avoiding doing any DIY for beekeeping for many months now 😉

However, the season is looming ever-closer and I want to try some new things.

My toolbox contains approximately equal amounts of disconcertingly sharp implements and elastoplast. I’m well prepared 😉

I’m also currently living very remotely. In the event of a bad injury I’m unlikely to ever trouble the staff in A+E … unless the accident conveniently coincides with the ferry timetable 🙁

I therefore decided to risk life and limb by building the things I need to try queen rearing using a Morris board.

I’ll describe full details of the method later in the year.

For me, this method should offer advantages due to the type of bees, the size of my colonies, the number of queens I want to rear and the period over which I want to rear them.

You can buy these boards (for about £30 each) … or you can build better ones for about a fiver from offcuts from the wood bin, a bit of queen excluder and a piece of aluminium. They are a bit fiddly to build, with four opening doors and a ‘queenproof’ slide, but the cost savings and satisfaction you gain more than outweigh the blood loss involved.

Here’s one I started earlier … a Morris board under construction

The very fact I’m still able to write this post shows that I managed to retain all my fingers. Whether or not the Morris board works 5 I consider that fact alone a success 🙂

Doing the splits

The Morris board works by allowing access to 5 frame upper brood box for defined periods. I therefore also needed a brood box divided in half.

I’ve been doing a lot of wax extracting recently and a couple of cedar boxes have cracked under the stress of repeated steam cycles. I split one down to its component boards, burning the bits that were unusable, but recycling one side into the central division of another old cedar box.

Split brood box – detailed view of my very poor workmanship

I’ll be queen rearing in two apiaries simultaneously, so will need two of these upper boxes. However, I only managed to salvage one sufficiently large board from the steam-damaged box.  Fortunately I have some cedar nucs built precisely (so clearly not by me 😉 6 ) to National hive dimensions, so I can use two of these side-by-side with the same design Morris board.

Late afternoon sun, 24th January

But queen rearing remains both a distant memory and a very long way off in the future. Until then it’s a case of enjoying the short winter days and drinking cappuccino in front of the fire.

Good times


Notes

Hammerite Garage Door paint is usually £15-20 a tin (750 ml). It’s worth shopping around as there’s quite a bit of variation. I found it remaindered and paid under a tenner 🙂

I reckon there’s enough in one tin to do two coats on 9-10 nucs as long as you take care not to over apply the first one. You could probably thin it a bit (though I’m not sure what with 7) but I’d take care you don’t create something that just melts the poly box.

Even at £20 it still works out at only about £2 a nuc. Considering these can cost £40-60 it seems like a reasonable investment of money to keep them looking smart for years.

And a good investment of time (it took me ~15-20 minutes per coat) … after all, what else are you going to do in the bleak midwinter?
