While the scout bee is performing her waggle dance, she stops periodically and shares some of the nectar that she gathered with the bees observing her dance. By sharing the nectar, she lets these bees know the scent of the flowers that they will be looking for. Click on the picture to enlarge it. You can see the scout bee in the center waggling rapidly as she makes the vertical straight-line pass of her dance indicating that the nectar source is in the direction of straight out the front door of the hive toward the sun. I am amazed at what the bees do. It is quite a sight to see in the bee hive.
