  1. WINTER

    It really is a very bleak day here today.  Snow is causing chaos over much of the country.  We’re luckier than most in our patch in Surrey.  We’ve had a little snow, a lot of heavy rain and strong winds.  The sky is grey outside the windows. 

    The Winter Solstice (the shortest day and longest night the year) was last week.  Although I doubt any of us have noticed it yet, the sun is gradually growing in strength and the days are starting to get just a tiny bit longer each day.

    During this time the beehives show little or no signs of activity and look abandoned.  However inside is a different story.

    This extra daylight will soon trigger a change inside the beehives.  The worker bees will start to feed the queen bee a little more food.  This in turn will trigger her to start laying increasing numbers of eggs.

    If the temperature is high enough honey bees will fly during the winter.  They’ll collect water to dilute their stores.  They’ll also collect pollen if any is available.  Pollen is a protein food for bees and so it is especially important for rearing strong healthy brood.

    (N.B. Brood is a term used to describe developing bees).

    SPRING

    As spring arrives the queen continues to lay more and more eggs each day.  By the time beekeeper does his/her first spring inspection the brood nest is usually quite large.  Forage is absolutely crucial at this time as there are more young bees to be fed.  The remaining winter work force is now very elderly and new young bees are urgently needed.

    Hopefully the days are sunny and mild and the bees are able to fly most days.  If so, the population will expand rapidly and quickly outgrow the hive.  If the beekeeper doesn’t give the bees some extra room this will trigger the congested bees to swarm.  Even with extra room the urge to swarm is strong and the colony may well prepare to swarm. 

    Swarming is the natural reproduction of the colony.  The bees will start to raise a new queen.  Once they are assured a new queen is on the way, they will stop feeding the old queen to slim her down ready to fly.  On a warm day, usually in the middle of the day, the old queen will leave the hive with many of the older worker bees.  Initially the swarm will land quite close by whilst the workers look for a new home to move into.  Then all at once they will all take off.  For a few moments the sky will be black with bees, but they rapidly disappear from sight on their way to a new home. 

    Whilst swarms look very scary, the bees are usually very placid as they have no home, stores or young to defend. *

    For a while the colony the swarm has left from will be quieter, but once the new queen takes over the egg laying duties of her mother, the population will rapidly grow again. 

    SUMMER

    As spring gives way to summer the queen’s rate of lay has increased to up to 2,000 eggs a day!!!!  No that wasn’t a typo – it really does say 2,000 eggs a day!!!!  All those young bees need feeding so worker bees forage from dawn until dusk (so long as it is warm enough and not raining).

    During the summer months colonies can reach 60,000 bees.

    The Summer Solstice (the longest day and shortest night) triggers another change in the bees’ behaviour.  Now they reduce the amount they feed the queen bee and her rate of lay drops accordingly.  This change means there are more adult bees available to forage just in time for the main nectar flow in late July and early August.  As there are less young bees to be fed, this means all the surplus nectar can be stored as honey in readiness for the winter months.

    AUTUMN

    During the summer months, worker bees will live for approximately 6 weeks.  In the winter months though the workers will live for up to 6 months.  The bees being produced in the autumn months need to be especially strong and healthy as these are the bees which will keep the colony going during the winter.  They are also the bees who will “kick start” the hive again in the spring at a time when they are very elderly and coming to the end of their days.

    Approximately 10,000 bees are needed to see the colony safely through the winter so as the days shorten the colony continues to reduce in size as the older bees die, and less young ones are produced.

    The bees will continue to forage when conditions are favourable.  As the days shorten and get colder the bees will form a cluster.  In the middle of the cluster will be the queen bee and any brood, kept warm by the worker bees.  The bees on the outside will “shiver” or vibrate their wing muscles which generates heat, keeping the entire cluster warm.

    Soon the Winter Solstice will arrive and the cycle will begin again.

    * If you see a swarm please don’t panic.  Many local beekeepers are happy to collect swarms.  If you take a look at the BBKA website you’ll find more details.  https://www.bbka.org.uk/help/do_you_have_a_swarm.php

     

  2. Up until the last few days most of us have been enjoying a milder than usual autumn, but the last few days have definitely turned colder.  Brrrrrrr

    I often get asked what happens to the bees in winter so now seems a good time for a blog about just that.

    The answer is - it depends on which type of bee it is.

    It is often assumed bees hibernate during the winter months and that is true of solitary bees and bumble bees. 

    Towards the end of the summer months bumble bee colonies will switch from producing workers to producing drones (males) and then new queens.  These will mate.  The new queens need to feed to build up their fat reserves ready for hibernation.  They will then look for a suitable nesting site, usually north facing so they won't be fooled into emerging too soon by the warmth of the sun shining on the nest on a sunny winter day.  The old nests and drones will die.  The new queens will emerge next spring to start the cycle again.

    Solitary bees also hibernate during the winter.  It depends on the solitary bee though in which "state" they hibernate.  Some remain as eggs, or larvae.  Some remain as a pupae and a few hibernate as adults.

    Honeybees however don't hibernate although they do, for the most part, remain in the hive.  During the late summer the queen's rate of lay will drop.  As more of the older workers die than new ones are being produced the number of bees in the colony will drop.  In the autumn, the workers will decide the drones are now "surplus to requirements" and there will come a day when all the drones are summarily evicted from the hive.  These drones will perish from starvation or cold.  The colony continues to reduce in size until the numbers reach about 10,000.

    As the weather gets colder the bees will cluster together around the queen and any brood.  The bees on the outside of the cluster will "lock" their wings and vibrate their flight muscles.  This generates heat and the temperature of the colony can be maintained.  As the bees on the outside chill they are replaced by warmer bees from the middle of the cluster.  The colder the weather the tighter the bees will cluster. 

    During the winter months honey bees will occasionally fly if it is warm enough.  Often on a sunny day honey bees can be seen collecting water.  They will use this to dilute the honey.  Honey bees need approximately 40 pound of honey to see them through the winter.   

    The warmer winters we've experienced recently has affected bees.  Some of the buff tail bumble bee queens don't go into hibernation at the end of the summer months, but instead choose to establish a nest.  If these nests are successful, in the spring they will produce new queens around the time the hibernating queens emerge.  Its therefore really important to provide as much winter forage as possible for the bees.  Mahonia is a fabulous choice as it continues to flower throughout the winter and will be one of the few sources of food available to bees.

  3. P1010643

    It's a busy week of events and talks this week, but this morning I decided to make the most of a few hours and have a long, autumn walk.  Armed with camera and Bug (my doggy companion) we set off for a  meandering walk.  

    P1010645

    It was a glorious morning - autumn sun shine, crisp leaves to crunch through, fungus growing at the foot of trees, a kingfisher darting along the river (to quick to photograph).  

    P1010642

    I spotted another large fungus (I have no idea of the names) growing on the side of a pile of what can only be describe as tree trunks.  Wandering over I spotted a bee heading in the same direction, and then another one.  Being ever curious when it comes to bees and what they might be up to, I went to investigate where they were going and that's when I spotted it.

    A colony of "wild" or "feral" honey bees living in the tree trunk!!!!

    P1010653

    When I first started keeping bees more than more than 10 years ago, I was taught that due to the problems bees were suffering there were no wild colonies and any there were would be sure to succumb to disease before long.  

    In recent years though I have heard more reports about wild colonies once again, but I didn't expect to see one on my walk this morning!  I have no idea how long this colony of bees has been in this tree trunk, but they well established and have obviously been there some months or longer.  

    Usually bees will chose a cavity with a much smaller hole than this one.  Its easier to defend for one thing.  So I'm a little concerned as to how they will fare during the winter.  However I am sure the bees know far better than we do, and I'm guessing that at the moment with all the warm weather and forage out there the colony is still quite large for the time of year.  

    I'm planning on checking back from time to time to see how they are faring and I'll share news of them as and when I have it.
