Episode Extra: A Flower’s Electric Field
In the “Electric Buzzaloo” episode I did on YouTube, I showed you not only how bees find flowers using UV vision, but also mentioned that they can sense a flower’s electric field. What does that look like?
This image captures the slightly negative electric charge that most flowers carry since they’re literally grounded. After being visited by one bee, it sheds some of that negative buzz to the positively-charged pollinator. If another bee comes along, it won’t be attracted to the less charged (and less nectar-filled) flower.
This maximizes a bee’s chances of visiting fresh flowers and not wasting their time at an empty well. Read more at Nature News.
