Wow... quite a wonderful image Isabel. Did you know that in their lifetime, a bee collects only the equivalent of about a soupe spoon worth of finished honey ? I asked a... what do they call them ? Apiculture or something like that ! Anayways... they know how many bees there are in a hive, by weight, and then, they know how many pounds of honey they extract by hives... they do the math and... voilà ! I thought it was quite amazing... and so is your photo of this worker.
