Bumblebees have a superpower: they can tell a tremendous amount about their world with electric fields. Pollen tends to have a negative charge, while bees tend to be positively charged. As the bee flies around, friction from the air rubs electrons off its hairs, resulting in fewer electrons and a positive charge. When a positively charged bumblebee rolls up on a negatively charged flower, the flower pulls on the bee’s hairs, sending a signal to the bee’s brain. Depending on how strong the pull is, the bee can learn how much pollen a flower has and even tell if other bees have recently taken its resources. When the bee lands, its positive charge interacts with the negative charge from the flower, changing the overall electric field. Therefore, just by sensing electric fields, a bumblebee can tell whether or not a flower is worth a visit.
