BEE WISE: “MULTI-TASKING BEES!” by Emery Dann
For example, if there are not enough foragers, younger bees can become foragers at an earlier age. This allows for greater hive flexibility. Bees also somehow know who goes in the swarm and who stays with the mother hive. Bees do not have to “pick a number”, to decide—like we do!” Do they read each other’s minds?
Instead of thinking of a single bee job one after another based on a bee’s age, we can expand the concept to a “colony need based model” with some job rotation. One good example of this are “heater bees”. These bees are a more recent discovery. Bees of almost all ages can become “heater bees”. They do this by detaching their flight wings and the vibrating their bodies while their wings are motionless. By doing this they can heat their bodies up to 111 degrees Fahrenheit in the brood area. Scientists have used infrared technology to discover these facts.
Good queens may leave empty brood cells to be used by heater bees to crawl in and keep the surrounding 70 cells at the right temperature. THIS MAKES IT VERY IMPORTANT TO GIVE THE QUEEN ENOUGH ROOM IN THE BROOD NEST SO SHE DOES NOT HAVE TO LAY IN THE CELLS SHE WANTS TO LEAVE EMPTY. I am not talking about “spotty brood” which is a problem of queen/hive weakness that may lead to beehive die off.
The normal brood temperature is kept by the nurse and house bees at 93 degrees. The bees emerging from this temperature have a normal hive job progression. When “heater bees” raise the brood temperature to 95 degrees, the brood that hatches prefers to forage more than to do other hive jobs. NOT CHILLING THE BROOD IS CRITICAL THROUGHOUT THE YEAR FOR THIS REASON! “Heater bees” are given food by supplier bees who feed the heater bees so they can keep a consistent temperature where they place themselves in the brood nest. Then other bees rotate in and become “heater bees” when needed. Every bee cooperates by doing their part of the work that needs to be done for the good of the hive!
The more we look into the life of bees in our hives, the more we can see bee “multi-job tasking” and job rotation involves complex decision making honey bee-havior!
