based on an article in The Times today
While flying, the bees gather a positive charge.

Positively charged bee hovers in front of a flower and detects the feint hum of its weak negative charge

sure that no bee has visited the flower it enters and the flower's negative charge is cancelled out

any bee approaching in the near future will not detect the hum of a negative charge and will look elsewhere thus not wasting effort.

Interesting stuff - I'd always assumed they were smelling the nectar in flowers rather than detecting electrical charge.

You never saw the "Bee" movie (animated). That is not how they do it in the movie... ;)

Very interesting... I think it may prove how distruptive windmills are to the ecosystem with their ultrasound noises.
