Bees sense electrical fields in flowers
Flowers “communicate” with bees via colour, shape and electrical fields. The latter was discovered only a few years ago and it remained unclear how bees could sense these signals. Now researchers discovered that bees’ hairs move rapidly approaching the flower. This signal is perceived in a distance of 10 cm and activates the nervous system of the insects. Bees’ hairs are light-weight and stiff, which probably makes them “dance” in electrical fields. The researchers are now interested if these signals can be also perceived by other insects.
