Nice find, I remember finding this relevant
tidbit interesting. Makes sense when viewing things holistically, as it would be rather taxing to visit each flower just to find it has been pollinated/no nectar atm.
Quote:shown that bumblebees can sense the electric field that surrounds a flower. They can even learn to distinguish between fields produced by different floral shapes, or use them to work out whether a flower has been recently visited by other bees.
