34.9*C in the shade

It was the hottest day of the year yesterday.
By quite a distance.
On my first visit to the apiary at 9am the temperature had already climbed to 26.5*C and the beelines had been supporting heavy traffic for hours.
The privet that they were returning with has been out for a few days now and the hive is starting to smell of it.
There's an inspection due for tomorrow so we can see whether they've started stashing it in that top box yet.

As the morning wore on it very quickly became Abroad Hot.
So after a quick look at the varroa tray, which looked very healthy (zero varroa and zero evidence of wax moth), I decided to leave the tray out for a while to help the flow of air in the hive.
Also, I realised that I still had a half entrance reducer in place covering the RHS of their entrance.
Quickly I suited up, removed the tape holding the reducer in place, prised it out of the grooves and away from the hive.
It looked like there must have been a pretty sizeable proportion of bees leaning against it because a big bloom of the little fellers hoofed out through the now empty space and got interested in me for a while before quickly realising that, actually, having a bigger front doorway was, in this heat, a vast improvement and got straight back to business.

Apart from the heat, for the colony it was pretty much business as usual all day.
At 8pm it was still 32*C and there were still flyers returning. There was also quite a gathering out on the landing board; it was a bit like a bee beach party.

8pm, still 32*C, out on the deck

By 10.30pm the temperature had dropped only to 28.8*C and it was dark. The foragers had stopped flying but the hive was still active. A large group of bees were still out on the landing board and the noise of 1000s of tiny wings beating inside the hive to try and bring the temperature down was significantly loud.

All Night Party

Hopefully it won't be quite so hot tomorrow and perhaps they'll find the newly filled water source at the back of Spike Acres soon. If they do, that should help them keep the temperature down.

It's Beginning to Look a Lot Like Spring at the BeesofSpike Apiary

Sunday the 3rd of March 

Today was the first truly spring-like day of the year. 
It was still too cold to open the hive, but the sudden change in the seasons meant that there was now plenty of action outside the box.


Apiary Diary: Observations

11.30am: Bright sun and feeling warmer than it had for ages. 
The Apiary thermometer was only reading 6.1C but there were already lots of flyers, a few returning with pollen.


Morning: still a bit chilly

12 noon:  A little warmer and significant numbers of bees now flying.
A larger proportion of bees were returning with pollen and there was constant activity.
The flight patterns seemed less focussed than summer foraging flights. 
Much of the activity around the front of the hive was less direct, more chaotic, very probably orientation flights.

Soon after this the activity died away to nothing, perhaps coinciding with it clouding over a bit.

2pm: The sun had emerged from behind the clouds and the temperature had risen to 10.7C. The bees were back flying again. 
The flights built up from a small start to large numbers of bees which caused a bit of a traffic jam and the odd ruck at the small winter entrance with lots of pushing and shoving to get in and out.


Winter entrance already looking a bit on the small side

This time there were significantly more bees returning with pollen.
There was also a variety of colours, implying that there are already a variety of sources out there somewhere.



Meanwhile, away from the Apiary, the back doors and windows of Spike Towers were open to let in as much fresh air as possible.
Judging from the shouts coming from inside, LandofSpike (who was at the far western borders of Spike Acres carrying out some maintenance on the Apiary structure) was soon aware that the fresh air was not all that was being let in.
There were quite a few bees inside too.

LandofSpike had to employ his trusty queen clip to gently capture, then liberate, all the bees trapped in the house.


Every home should have one

This quite unexpected incursion of bees into the house is interesting because the only other time it has happened was on the bees' very first day in the Apiary, when there was, for one day only, a constant stream of the fellers getting trapped in the conservatory.

LandofSpike presumes these were bees scouting the new territory for sources of nectar and pollen. 
Having returned to the hive with the news that there was none to be had in the house, no more bees bothered to come visit all season long.
So, bees in the house on the first proper forage day of spring, isn't such a surprise after all. 
It was simply scouts re-mapping the territory.

This first day scouting may also account for the increasing returns of pollen as this first day progressed.
In the morning areas rich in pollen had been discovered, and the locations had been relayed to the colony, so that, in the afternoon, foragers knew exactly where to go.



Next up, a bit of Apiary maintenance and then, the first inspection of the new season.

Winter Feeding for the BeesofSpike: Getting Fondant into the Hive

Tuesday 29th January.

After 3 weeks of wintry weather including sub-zero temperatures and a liberal helping of snow, the weather changed for the better and, for one day only, the temperature in the Apiary rose to a daytime high of 13.4C.

It was mild enough for the bees to be out stretching their wings and finding forage.

This was the window of opportunity.
Having failed to get fondant into the hive during the mild spell over Christmas and the New Year, this was the chance to make amends.

Adding fondant to your bees' stores of honey helps to decrease the likelihood of the colony starving to death during the long winter months.
It's not good to expose the inside of the hive to the cold so inserting the fondant would have to be done swiftly. The plan was to keep the roof off for the minimum amount of time possible.


It was also the time to see if the new homemade wooden eke would fit onto the polystyrene hive.
The fit had been tested on a spare hive but this was going to be its first use on a live box full of bees.


Dry fitting the unpainted eke on a spare brood box

An eke increases the available vertical space between the top of the frames and the base of the roof or top feeder. 
Without an eke in place there would be no room for the block of fondant.






It would also be the first chance to have a peek inside the hive since the last inspection of autumn. 
And the only chance to look inside before the arrival of the nice spring weather.



The operation went incredibly smoothly.

After smoking the entrance, LandofSpike and Neighbour Jane popped the top off the hive and gave them another small puff of smoke. 
The bees were, as usual, extremely placid and accommodating.

A quick inspection revealed that there was still plenty of capped honey left in the super and in the, ahem, large chunk of burr comb also nestling in the same super.
All seemed well.

The fondant packaging was slit open across the underside to expose the sugar and then placed on top of the uppermost frames so the bees could access it directly from below.

2.5kg of fondant in place, eke in place and, erm, prodigious amounts of burr comb in place.
However, you can see plenty of capped honey on frames 2 & 3 and on the burr comb.

Adding the homemade eke was extremely satisfying.
It was a snug and perfect fit.

Like a glove...

Perhaps the EPS hive makers could consider stocking EPS ekes for their beebox system as it is a pretty essential bit of kit and seems like a bit of an omission from their catalogue.
However, it's so relatively simple making your own that the lack of a store-bought eke is no great hardship.



So with the roof safely strapped back down, the BeesofSpike have their supplementary winter feed sitting nicely on top of their own stores. 
Their hive is now shut to humans until the spring.


Although the winter closedown is in place, LandofSpike will still be observing the little fellers on a daily basis, observing any activity and recording temperatures in the Apiary. 
He also needs to construct some new frames, paint some supers and brood boxes and build a new hive stand. 
And he really needs to get reading and bone up on what to do in the springtime.

The BeesofSpike Apiary is Snowbound


The winter freeze has finally arrived at the BeesofSpike Apiary.
After an extremely mild holiday period, which saw workers foraging on winter blossoms, the weather has taken on a more seasonal feel.

Initially, on the 17th of January, as the temperature dropped, there was the traditional 'light dusting' of snow.
The next day the light dusting became a slightly heavier dusting. 
There was more snow overnight and more the next morning. 
It was now just deep enough for LandofSpike to take the kids sledging. Just deep enough for him to mangle himself on the slopes and end up in A&E.

Then, on the 21st of January, as the snow kept falling and the temperatures continued to drop, it became, at least by London standards, proper snow.


Spike Acres looking a bit wintry. The hive is just visible through the screen
LandofSpike knew that, despite the freezing temperatures, his bees would more than likely be quite cosy, all clustered together, safe indoors.
But as the snow got deeper, he realised that a 7-10 cm covering of snow sitting on the bees' landing board would block the tiny winter entrance to the hive and they'd all be trapped inside.
Even a 2 cm covering of snow would have covered the entrance. It was obviously time for a bit of beekeeper intervention.

The Apiary. The Landing Board is covered in snow
However when LandofSpike got to the Apiary, intent on clearing their front path, he realised that his snow-shoveling skills were not needed.
The landing board, like everything else, was indeed covered in a thick layer of snow but the area around the entrance was completely snow-free and open for business.
This wasn't the work of the bees clearing the snow away with tiny shovels but was a result of the warmth of the hive radiating from the doorway and melting the snow in the immediate area.


The warmth from the hive keeps the entrance clear
As a first year beekeeper LandofSpike was initially amazed by this but, of course, he realised that it's actually just very logical primary level physics.
That aside, it is however a brilliant example of the natural world coming up with a simple and elegant solution to a possibly disastrous problem.
Again the beekeeper needs to do nothing apart from observe and learn. Honeybees have, of course, been dealing with snow just a tiny bit longer than LandofSpike has been dealing with being a beekeeper.



As the snowy days continued LandofSpike noticed that the numbers of dead bees in the space immediately outside the entrance gradually increased.
It wasn't enormous numbers but there was a definite build up of bodies.
Initially he thought that it might be fearless or foolhardy flyers unable to deal with the freezing conditions but it seems more likely that this was the work of mortuary bees clearing out dead bodies but being unable to get them any further than the front step because of the weather.

Just bung 'em on the front step guys, we'll get rid of 'em once it warms up

There are always casualties though.
Venturing out in these temperatures is a guarantee of more or less certain doom.
It's just too cold for a honeybee to function.
LandofSpike found this apian equivalent of Captain Oates lying perfectly frozen in the grounds of Spike Acres, alone in a pristine field of snow. It was only a metre from the hive.

"I am just going outside and may be some time."

Apart from these few winter observations there has been no sign of the bees.
Sensibly, they have been staying inside keeping toasty.


But the snow won't last forever.
And on the very next warm, dry day LandofSpike's next beekeepery task will be to get some fondant into the hive to supplement the bees' winter stores.
It's also an opportunity to take a quick look inside the box while the lid's off.

We'll also find out if that newly fashioned custom eke is any good.

Merry Christmas and a Happy New Year from the BeesofSpike Apiary

The old year is now fast receding into the dim and distant past.

Not receding into the dim and distant past is LandofSpike's remarkably resilient cough; a legacy of a festive season of which he spent every single day afflicted with A Ghastly Illness. 
Moan, whine etc. 

His Man Flu was so virulent that he was unable even to drag himself to the western borders of Spike Acres to monitor his bees.
So the daily Apiary observation chart, over the Christmas & New Year period, records nothing apart from a maximum temperature of 12.2C, a minimum of 3.5C and a scribbled note that it had been rainy but mild.

The bees didn't seem to mind his absence though. They just carried on without him.


Another consequence of The Great Illness, but also partly due to A General Uselessness, was the LandofSpike Christmas cards failing to meet their December deadline.
So, in time honoured fashion, the Apiary Christmas Message is making a belated, yet still heartfelt, appearance.


LandofSpike and his Bees would like to wish all you Friends of Bees a belated Merry Christmas and a Happy New Year.
Join them for more bee-related nonsense in the coming year.

Foraging in January

Yesterday, as reported on this blog, the bees were out and about in great numbers due to the unseasonably mild weather.

While in the Apiary, LandofSpike also noticed a few workers returning with polllen. 
There was uncertainty as to where this pollen could be coming from so early in January.

Today, the 9th of January, it's still sunny and is a pleasant 9.3C in the Apiary. 
And, with bees still in the air, the mystery of where the pollen's coming from has been solved.


It now transpires that at least some of it was coming from the thicket of Mahonia just outside the front gates of Spike Towers.
Mahonia is a dense little shrub which bears blue-black berries and is armed with some pretty spiky and tough evergreen leaves.
The council's favourite loiterer deterrent 
The local council plant Mahonia in places where it deems people need to be deterred from loitering. 
Seemingly, the raised bed area in front of Spike Towers has been designated a No-Loitering Zone as they've filled it with a healthy patch of the stuff.
This has the happy bonus of supplying the BeesofSpike with a reliable local source of winter forage.


Bright January sunshine, bright yellow flowers

At this time of year Mahonia has the most brilliant yellow blossom. It's amongst the earliest bloomers of the year.
And the BeesofSpike were all over it.

NeighbourJane takes the credit for spotting foragers industriously working the Mahonia in the sun this morning and LandofSpike was able to get some nifty photos to record the event.


Pointy leaves to deter humans, Lovely yellow flowers to attract bees

The bees don't usually have many opportunities to fly in the winter months but, if it's mild enough, Mahonia can now be officially added to the Winter Forage List.

More Winter Activity at the Apiary

It's 1 o'clock on the 8th of January. The Apiary thermometer is reading 11.9C.

And the BeesofSpike are taking another opportunity to stretch their wings.
The Apiary is alive with flying bees.

The whole colony seemed to be out enjoying the mild winter weather today

It's good to see the little fellers out in such healthy numbers.
However, the flightpaths seem much less direct and focussed than they are during pollen gathering.
An Apiary visitor is usually able to judge where to sit to watch the comings and goings of the workers, but this flight is much more random, with bees seemingly flying with no particular destination or direction in mind.
Just being in the Apiary today more or less guarantees that you'll be crashed into, landed upon and, generally, be in the way.
Mainly it looks like one big orientation flight but LandofSpike has seen a few workers returning with pollen.

All this excellent winter activity would seem to imply that, so far, the colony seems to be surviving the winter.
LandofSpike hasn't supplemented their winter stores with any fondant yet. As a first year beekeeper this is a source of worry. Opening up the hive at this time of year is not the best of ideas but the fondant will have to be introduced at some stage.

There's also the burr comb to get rid of. Oh yes.
It's a beautiful bit of construction, and fully loaded with winter stores, but unfortunately it doesn't comply with Apiary building regulations.
LandofSpike left it in place for them to use over winter but excising it and restoring order in the spring should be interesting.
The bees won't like it.

A Thermometer for the Apiary


The BeesofSpike Apiary has a sparkly new min/max thermometer. 
It was installed in a sheltered spot on the western perimeter wall on the 19th of November and has now been in place for a month.


LandofSpike had previously been relying on the BBC's online, London-wide weather forecast for all his bee-related activities but had reached a point when this was no longer site-specific enough. 
Also, at times, it had proved to be a mite inaccurate. 
LandofSpike can recall for you a day in July when he was watching yet another biblically proportioned rainstorm turn the grounds of Spike Acres into a swamp. Simultaneously, on their website, the Beeb were defiantly claiming that the sun was, had been and would keep on, shining brightly.
This clearly wasn't good enough.


His legacy lives on

So after a bit of research, the most robust, accurate and bee-budget-friendly min/max thermometer was ordered and hove up at Spike Towers just in time for his birthday.
At this point thanks go out to the venerable and bee-friendly MumofSpike who funded the purchase.

It's billed as a greenhouse thermometer but does seem to function just as well in the great outdoors. 
Although just to be on the safe side LandofSpike has built it a little roof to keep the rain off.

Operation couldn't be simpler. 
The middle reading is the current temperature. 
Top and bottom are the maximum and minimum temperatures recorded since the reset button was last pressed. 

Maximum 14.1C, Current 13.9C, Minimum 13.7C... Simple. 


And it's been a great success.
The daily chart of maximum & minimum daytime and nighttime temperatures, when correlated with LandofSpike's general Apiary notes, make it easy to match bee activity with fluctuations in the weather.



As a consequence, The Apiary's autumn and winter thermometer-related highlights so far include these thrilling events:

   After a season-shifting cold snap starting on the 26th October (which arrived too early for the new device to record), the daytime temperature in The Apiary hovered, generally, between 11C and 14C. 
This still allowed plenty of foraging and a variety of different coloured pollens were seen being brought back to the hive. 
Despite the continued activity bee numbers were noticed to be steadily dwindling.

   The rain and cold of the 24th of November effectively ended any significant flights.
After that it didn't get back above 10C and was often well below that.
Around about now any interest in the top feeder seemed also to end.
By the 29th of November a nighttime dip below zero heralded two weeks of wintery weather and flying bees disappeared off the radar.

   As reported in the BeesofSpike post 'A Mild Winter's Day', a little warm spell on the 15th of December saw bees out and about for a little while but generally, the new Apiary Thermometer has so far recorded only seasonally cold temperatures.


Winter has set in at the BeesofSpike Apiary.

Get Thee Behind Me, Jet Stream


Somewhere the sun is shining, 
So, honey, don't you cry,
We'll find a silver lining,
The clouds will soon roll by. 

So sang Elsie Carlisle, vocalist for the rather excellent Ambrose and his Orchestra in 1935.

And now, seventy seven years later, the clouds are indeed about to roll by. 
And the place where the sun is about to shine is right above the BeesofSpike Apiary.


Yes indeed, the English summer is, eventually, almost here.
This is due to the Jet Stream finally shuffling back up into its customary, more northerly, position after having lingered too far south for far too long.

And happily, it's taking its appalling weather with it.
No more of this for a while

It has rained every day at the BeesofSpike Apiary since the bees arrived.
The Apiary's newly laid grass has more or less disappeared, and the yet-to-be-named Hive Number One stands glumly in a depressing sea of mud.

But all is about to change.



Today, Friday 20 July, apart from being Mrs LandofSpike's birthday (Many happy returns, of course) marks the end of the interminable Jet Stream-induced rainy season.

And about time too

Tomorrow, it will be sunny all day. 
And the forecast is set fair for as far into the future as LandofSpike's weather-predicting seaweeds can tell.
The BeesofSpike will like this.
It's at last a chance to get a concerted spell of foraging under their belts before they have to hunker down for their first winter at the Apiary.

Inclement Weather at Apiary Central

LandofSpike checked out the bee activity at Apiary Central this afternoon.
Based on his 5 minutes of HiveWatch it looked like all flights had been cancelled for the day, as it was cloudy, a bit nippy and raining on and off.
Those bees aren't daft. After last week's unseasonally high temperatures of 23C, this little cold snap isn't really the best of weather for hungry workers who want to zip out and get at that springtime pollen.
And according to LandofSpike's collection of weather-predicting seaweeds, it's going to be lashing down with rain and hailing tomorrow.
Lovely. Wrap up warm little honey bees.
The Honey Bee doesn't like it when it hails

It's not just Honey Bees... An Exciting Seaside Bumblebee Adventure

LandofSpike was in Hometown-on-Sea at the weekend.
Temperatures on Saturday, after a gloriously summery week, were back to bee-worrying single figures, but Sunday was again warm and sunny.
Consequently LandofSpike spotted quite a few bumblebees out foraging amongst the flowers whilst he was taking the air with his family on the prom, just about as far east as England gets. On our left was all of Blighty, on our right was nothing but steel grey sea until you get to Holland.

Suddenly a cry of alarm, "Emergency! Bee Down!"
One of our number had spotted an upsidedown Bumble on the ground in front of us, too exhausted to get back to its colony. Perhaps it had been weakened by yesterday's cold snap, perhaps it was just fagged out.

So, now officially 'A Friend of Bees', LandofSpike swept into action. He scooped up the stricken Bombus and relocated her to a lovely pollen filled flower, a goodly height off the ground.

Good deed for the day done, LandofSpike watched proudly as the newly rescued and revived bumblebee flew off along the promenade, only to see it, 20 metres later, detour sharply Eastwards across the beach, zigzag out across the breakers and plunge, kamikaze-style, into the North Sea.

LandofSpike didn't attempt a further rescue but decided to go to the cafe for a large helping of fish 'n' chips instead. They were very tasty.
