Old and new duds

The Beast from the East ...

The Beast from the East …

Despite the best efforts of the Beast from the East 1 Spring is definitely on the way.

The snowdrops and crocus have been out for some time, willow is looking good, large queen bumble bees are searching for nest sites and the temperature here in Fife has consistently reached double figures during the warmest part of the day for the last week.

Consistently … but only just and only briefly.

Pollen boost

Pollen boost …

Consequently it’s too cold for full inspections and the only colonies I’ve been ‘in’ are the two described below. However, I’ve not ignored the others. I’ve lifted the crownboard on most colonies to determine their approximate strength (or just peeked through those with perspex crownboards which is even less intrusive) and have continued to heft colonies to see if they have enough stores. Those that were feeling a bit light have had a fondant top up. I’ve also given several colonies a pollen boost to help them rear early season brood.

Other than that – and moving colonies to the new bee shed – I’ve left them well alone.

Early season checkups

On the warmest part of the warmest day of the week I visited the apiary to check the colony strength. With the exception of two, all were flying well with foragers returning laden with pale yellow pollen.

However, two were suspiciously quiet, with only a handful of bees going in and out 2.

A pretty small handful.

Almost none of the bees returning to these two colonies carried pollen.

One was a five frame poly nuc in the bee shed. This had been made up in mid/late summer while the parental colony was requeened. The old queen, a frame of emerging brood with the adhering bees and a frame of stores had gone into the nuc box. The little colony had built up reasonably well going by my infrequent peeks through the transparent crownboard, but not well enough to move them to a full hive for the winter.

The other suspiciously quiet colony was a full (or full-sized 🙁 ) hive headed by one of the older queens in my apiary. Most colonies are requeened annually or every other year, but this one was reared in my first year in Scotland (2015) 3.

I popped the lid off both colonies and examined them in greater detail. It wasn’t the recommended ‘shirtsleeve weather‘ by a long-shot, but I feared the worst and didn’t think a bit of cold would do these two any further damage.

Unfulfilled promise

The nuc contained about a cup full of bees and a small, unclipped pale queen.

Overwintered virgin queen?

Overwintered virgin queen?

This definitely wasn’t the queen I’d put in the box last August. For whatever reason, the colony had clearly replaced the queen late in the year. It hadn’t swarmed, so it looks like they’d tried to supercede the old queen. Going by the total absence of worker brood I presume the new queen hadn’t mated successfully, or at all, and that she was a virgin.

She wasn’t running about skittishly like new virgin queens do, but she wasn’t doing anything very useful either.

There were a few drones in the colony and one or two sealed drone cells. Whether these were from unfertilised eggs laid by the queen, or laying workers, is largely irrelevant 4. The colony was doomed …

Worn out

The full sized colony was only full sized in terms of the hive it occupied. Inside there was another rather pathetic cupful of bees together with a very tatty, marked and clipped queen 5. There was more paint on her head than her thorax and I remember marking her with a very ‘blobby’ Posca pen. This was the queen I’d expected to find in the box.

Old and tired ...

Old and tired …

There were no drones in this colony, but no eggs either. There was also no sign of a second queen or evidence of attempted supercedure. I suspect the ageing queen simply ran out of sperm, stopped laying and never got started again.

Sometimes old queens turn into drone layers and sometimes they just stop. I’m not sure why they exhibit this different behaviour. It might actually reflect when they’re detected. I think I usually find drone laying queens a bit later in the Spring. Perhaps a failed queen starts laying (unfertilised) eggs only once the ambient temperature has risen sufficiently to help the much-reduced numbers of workers keep the brood nest warm enough?

That’s guesswork. It’s still cold here, with frost most nights. The small number of bees in the colony would have been unable to maintain the mid-30’s temperatures required for brood rearing. It’s surprising they’d survived this long.

Health check

Neither colony had any obvious signs of disease. The floor of the full hive was thigh-deep – if you’re a bee – in corpses.

Winter losses ...

Winter losses …

However, a good poke around through the cadavers failed to find any with signs of the deformed wings that are indicative of high viral loads. I hadn’t really expected to … the Varroa loads in this colony in the late-summer and midwinter treatments had been very low.

Corpses ...

Corpses …

Lose them or use them?

Clearly both queens had failed. Both were despatched. To keep them in the vain hope that they’d miraculously start laying again would have been a waste of time and, more importantly, other bees. The virgin would now be too old to get mated and there won’t be drones available here for at least 6 weeks.

This left the dilemma of what to do with the remaining bees. Both colonies were apparently healthy, but too small to survive. In the autumn the obvious thing to do is to unite small healthy colonies with large healthy colonies. This strengthens the latter further and helps them get through the winter.

However, this is the Spring. There were probably no more than 300 bees in either of the failed hives. All of these bees would have been at least 3 months old, and quite probably significantly older. They were unlikely to live much longer.

Furthermore, uniting these small colonies with larger colonies in the apiary would have caused disruption to the latter and increased the volume of the hive to be kept warm. Neither of these are desirable.

I therefore shook both small colonies out allowing the healthy flying bees to redistribute themselves around the half dozen strong hives in the apiary. Before shaking them out I either moved the original hive altogether or – in the case of the nuc from the shed – sealed the entrance, forcing them to look elsewhere for a colony to accept them.


Colophon

The term dud is used these days to mean a “thing that fails to function in the way that it is designed to”, with this usage dating back to the 1914-18 war where it referred to shells that failed to explode. However, the word is much older. Its original meaning was a cloak or mantle, often of coarse cloth, with references to the word dudde dating back to the 14th Century. Over the next few hundred years the meaning, in the plural duds, evolved to mean clothes and – more rarely but more specifically – ragged, shabby clothes or scraps of cloth. This seemed appropriate considering the tatty state of the old marked queen …

 

 

Footnotes

  1. A winter storm that brought snow to the UK in mid-March and effectively paralysed the country for several days … readers in Rochester, NY who get 100″ of snow a year would have wondered what all the fuss was about.
  2. A classic D’oh! moment. I’d talked the night before at Peebleshire BKA (really excellent cakes!) and had said something like “I’ve had no winter losses so far”. I spoke too soon.
  3. Ignore the colour marking … I alternate white and blue only as I’m colourblind and these are the only two colours I can clearly discriminate in the hive.
  4. I suspect the latter. You can see a few eggs attached to the sidewall of the cells towards the top left hand corner of the image, with multiple eggs per cell … a classic sign of laying workers.
  5. As an aside, these bees were in a Swienty poly brood box with an open mesh floor and a 50 mm block of Kingspan under the roof. The total volume of bees was smaller than a tennis ball. In the first three months of the year the average temperature has been less than 3.5°C, the lowest almost -9°C and about 50% of the nights have had ground frosts. This colony was not in the bee shed.

    Useful article. I’ve a small colony that I suspect went into the winter queenless. Had a quick peep a couple of weeks ago on a reasonable day. 3 frames bees and no sign of queen, eggs or brood. No drones either which was interesting as it went into winter with 2 frames of them.
    Thought they’d have died out, but they’re still going. I’d shake them out, except that in keeping with Seeley wisdom, my colonies are spaced out. The nearest nuc is about 20 yards away, and the next nearest hives, 50 yards away.
    Options, put them in a nuc and let them die out. Take to another apiary, in a nuc and shake them out there. Am I missing anything and are there any other options?

      Drones are always ejected in the late autumn, so it’s no surprise they’re absent now. If they’re definitely disease-free (and queen free 😉 ) I think the only option that saves some of the bees is to shake them out in front of a strong colony in a different apiary … or unite them if it’s warm enough where you are. I’d be happier uniting 3 frames of bees than the cupful I describe above. If you shake them out where they are most will likely perish as they’ll return to the site of the original colony. In a distant apiary they’ll mill about for a while and then try and enter the nearest hive. Choose a warm day.

    Sulpher is really the best option, you are not sure if there is another disease they are carrying to cause them to drindle like that – an unmated queen should still have plenty of bees as the attrition from raising replacement brood is not present- so there could be another root cause or contributing factor.. Dead bees dont pass on disease….

      Possibly, but too late now … however, the (suspected) virgin was in a nuc box so was never as strong as a full colony and they presumably replaced her late(ish) in the year. The last inspection was in early/mid September I think, so they might have had no brood since late that month, reducing the amount of winter bees raised and meaning what’s left are probably 6 months old now.

    Hi David,
    whats your pollen supplement?
    I gave mine patties this year, and I am really happy with the results.
    800g Soya flour
    200g bulk brewers yeast (actually found a 5kg/15quid bucket online sold as horse feed supplement – bees seem to like it too)
    a good splash or rapeseed/canola oil
    1kg bee feed.
    All colonies took it up really well, I started feeding when the hazel blossemed as I figured it would be a reasonable time to start without prematurely starting brood production. The colonies all look very good now. I’ll be giving my nucs these patties aswell to give them a leg up..

      Hi Calum
      Mine was straight pollen … irradiated and purchased in bulk. I probably overdosed them a bit this year and should have used about half the amount. We’ve gone from colonies being almost always clustered to foraging well in about 10 days. They’re currently piling in yellow and orange pollen … and ignoring the remnants of the stuff I generously left for them 🙁
      I’ll recover the latter and use it sprinkled into a brood comb in my queen cell rearing colonies.
      Do you have a link to the horse-supplement you sourced?
      Cheers
      David
