Yes. Bees can detect weak electric fields around flowers, which may help them distinguish floral signals and learn whether a flower was recently visited. Research at the University of Bristol found that mechanosensory hairs on bumblebees respond to weak electric fields. Electric cues complement colour, scent, shape and nectar rewards; they do not replace them.
A bee and a flower carry different charges
A flying bee can accumulate positive charge, while a flower often has a different electrical potential relative to its surroundings. When a bee approaches, the weak field around the flower changes. Researchers have shown that bumblebees can detect and learn from these floral electric patterns. [1]
A flower’s electrical signal can shift after a visitor arrives, giving the next bee another cue about whether nectar may remain. It is one part of a complex interaction, not a guarantee that a particular flower is rewarding.
Tiny hairs can detect the field
Experiments at Bristol found that small mechanosensory hairs on bumblebees move in response to weak electric fields. The movement can stimulate sensory cells, providing a plausible way for the bee to detect a field without touching the flower. [2]
The hairs are not electrical wires. Their physical movement turns an electric force into a mechanical signal the nervous system can process.
Electricity joins colour and scent
Bees combine many cues while foraging: colour, odour, shape, temperature and learned experience can all matter. Electric fields offer an additional short-range signal, especially as a bee approaches a bloom.
The discovery broadens our picture of insect senses, but the field is still developing. Research continues on how different species detect electric cues and how pollution or environmental changes may affect them. [3]
