Bees That Watch Bees


Picture this. A bee with her tiny face pressed against a window, spying on other bees so she can see where the treasure is hidden. Sounds ridiculous to me, but it turns out to be true.

The experiment

In 2013, Canadian scientists presented a puzzle to four different bumble bee colonies. The bees had to fly to blue artificial flowers that had sweet syrup hidden beneath fake plastic petal-discs. Two colonies were given the task of finding the syrup without any training or help from the researchers. They failed miserably. But bees in two other colonies were helped in one of three different ways:

a) dead bumble bees were glued to the partially hidden syrup feeders;

b) successful bees were allowed to talk to recruits and explain where the syrup was hidden; or,

c) bees were allowed to watch their friends foraging.

In all three of the assisted training experiments, the bumble bees successfully found the partially obscured syrup. Unassisted and untrained, the bumble bees went hungry. Properly trained, they eat. You may read the experiment’s details here: Social Learning in Bumblebees”.

The University of Guelph researchers – Hamida Mirwan and Peter Kevan – are not sure how the bees communicated the foraging trick to their hive mates. They write, “The means of in-hive communication are not understood and warrant intense investigation.” Indeed it does. How on earth could one bumble bee tell others to “fly to the blue plastic flower, don’t be fooled by the big bright fake petal, but look under it, near the back, and you’ll find a hole you can stick your tongue into and Wow! you’ll be surprised by the sweetness of the extrafloral nectaries on those artificial flowers!”  That’s amazing communication.

This points to seriously flawed bee-brain reasoning – it should be apparent to even the most inept bumble bee that the dead bees had found nectar, then died. Shouldn’t this be a warning to other bees? I think smart bumble bees would have said, “Poisoned. They’ve been poisoned by the artificial flowers.” They should have put two and two together and decided it was a trap, not a treat. But the experimenters used bumble bees. I don’t think honey bees would have been as foolish.

Finally, we have the test bees who were allowed to watch. No whispering, no communication, just peeking through the window while other bumble bees worked. I think that this is almost as amazing as the talking bees. (Almost, but not quite.) The bees that watched the foraging bees saw which colour flower to visit and where the syrup was hidden. Can you imagine the thought process involved?  “Look! There’s Gertrude. She’s only going after the blue flowers, but silly bee, she’s not landing on top the petals… oh, wait. I get it. The syrup is hidden below the petals. Clever.”

Practical applications

bee-watching-tv-2Some people accuse scientists of conducting pointless pure research, but I can see a great application here. Educational bee documentaries. Small mp4 players should be placed inside honey bee hives. A movie switches on at six in the morning. It’s just a little movie about bees working almonds. It loops continuously. The plot is like this: Bee approaches trees, gathers pollen, then the actor-bee is filmed flying to a different cultivar to gather more pollen, assuring cross-pollination. Maybe subliminal messages could be included – flashes of fat happy larvae being fed beebread, for example.  After ten minutes, the theatre shuts down, with a repeat show every hour until 4 pm.

For pollinator bees trucked in from out of state, the movies might play during the two-day drive – sort of like in-flight entertainment. Then when the poor bees are set out in the almond groves, they’ll feel like they are in a comfortable, familiar surrounding and they can get right to their job of working themselves to death.

Beekeeping can either be a full time profession or an easy hobby. Nevertheless, more often than not, what began as a hobby would turn into a profession. But you cannot simply decide and tell yourself you will start to do beekeeping. Before starting on any avocation or profession, you need to have comprehension and adequate knowledge on the field that you’re going to enter. If you really have been putting off your curiosity about beekeeping for quite a while, then it is about time to indulge yourself. Bee farming may look easy; learning the basic beekeeping lessons can enable you to get away to a good start.

What does a beekeeper should understand?

First, you should have complete interest on beekeeping to begin at the right foot. You should have also agreed to share your dwelling space. There are possible dangers in beekeeping that can hurt you but your family also. If you decide to allow the bees inside your living space, then you certainly must know the supplies and equipment that you will use for beekeeping. Your focus is not only to build an income by selling honey; a good beekeeper should have a keen interest and passion in rearing bees.

An apiarist ought to know the right location for the beehives. You have to make sure that beekeeping is allowed in your town if you decide to place your beehives at your backyard. There are several areas restricted to beekeeping; you should get permission about this.

Beekeepers must know whether beekeeping supplies can be found in the place where the beehives are situated. When you need to attend a local beekeeping store you may never understand; it’s best that a nearby beekeeping shop is not inaccessible.

Equipment and protective supplies can also be important for beekeepers to understand. Understand the appropriate suit to pick to keep you from any possible risk in beekeeping.

If you are not able to harvest honey all the attempts that are beekeeping would be ineffective. The methods should be known by a beekeeper in collecting the honey in the comb; beeswax is also part of the yields in beekeeping.
