Go Against the Flow Bees get their directions from the sun. They learn their positions from how the landscape moves across their field of vision. As a bee flies, the objects below it enter its field of vision, flow across and then exit on the other side. Scientists call this optical flow. Say your goal is toward the sun.
Bees use the angle of optical flow to compensate for the wind.
In a crosswind, you will see the angle of flow will not be in line with your travel. So in spite of their tiny brains, bumblebees appear to be geniuses in navigation, geometry and physics. ABC News Internet Ventures. Click here for Terms of Use and Privacy Policy applicable to this site.
