Honeybees accumulate charge as they fly, and they transfer charge to the flowers they visit. honeybees are able to sense electric fields; tests show that they can detect a change in field as small as 0.77 nc. honeybees seem to use this sense to determine the charges on flowers in order to detect whether or not a flower has been recently visited, so they can plan their foraging accordingly. as a check on this idea, let's do a quick calculation using typical numbers for charges on flowers. if a bee is at a distance of 24 cm, can it detect the difference between flowers that have a +30 pc charge and a +40 pc charge?
