The Invisible Electrical Conversation Between Bees and Flowers
Experiments show that bees can distinguish the electric fields surrounding flowers, and that the visit of a naturally positively charged bee changes those fields. In honey bees, the perception of electric fields through the antennae has been demonstrated.
When a bee flies, it does not see only colours, smell only scents, or search only for nectar.
Around it, and around the flowers, there is another invisible world — the world of electric charges and electric fields.
A bee in flight usually builds up a positive electric charge. This happens as it moves through the air, through the action of its wings, and through friction between its body, the air, and plants. It is somewhat like combing hair with a plastic comb, when static electricity builds up. Bees lose electrons and thus become positively charged.
Flowers, connected to the ground through their stems and roots, often have a different electrical potential. They tend to become negatively charged. As a result, a weak electric field forms between the bee and the flower.
It is invisible to humans, but not to the bee.
A flower is not only colour and scent
Until now, we have been accustomed to thinking that a bee finds a flower by its colour, shape, scent, and ultraviolet patterns.
All of this is true.
But a flower also has an electrical “signature.”
The different shapes of petals, the arrangement of stamens, and the flower’s closeness to the ground influence the form of the electric field around it. For a bee, this may be another point of reference — something like an invisible map around the plant.
What happens when a bee lands on a flower
When a positively charged bee lands on a flower, it transfers part of its charge. The visited flower changes its electrical condition, becoming less negatively charged because it loses electrons.
This change is not permanent. After some time, the flower gradually restores its previous electric field. But for a short period, it may carry a trace that it has recently been visited. A bee in flight, circling around flowers, may be able to detect the flower’s weaker negative charge. If that is the case, there may be little reason to land on such a flower. Its nectary may already be depleted, its stigma may already have pollen on it — meaning that the plant may have been pollinated and pollen from the stamens may already have been collected.
If a flower has just been visited, part of its nectar or pollen has probably already been taken. There is no point in a bee wasting time at a place where the reward is small.
Through the electrical signal, it may receive additional information: “There has probably already been a visitor here.”
How a bee senses electricity
A bee senses electric fields through their mechanical effect on its body.
The extremely fine hairs on the bodies and heads of bumblebees can move slightly under the influence of an electric field. This movement is converted into a nerve signal.
In honey bees, the antennae also play an important role. An electric field can cause extremely slight movements of the antennae, which are detected by sensory organs at their base.
Thus, a bee does not “see” electricity in the way it sees light. Rather, it senses it as an extremely subtle movement and change in the space around it.
Why this is useful for the bee
In nature, every second matters.
A bee must visit many flowers, collect nectar and pollen, and return to the hive with as few unnecessary flights as possible.
If it relied only on colour and scent, it might land on a flower that had just been emptied by another bee.
The electrical signal adds another layer of information.
It does not work on its own. The bee combines electrical traces with colour, scent, shape, ultraviolet patterns, humidity, and its previous experience.
This makes the search for food faster, more economical, and more efficient.
Electricity also helps with the transfer of pollen. Pollen is negatively charged and is attracted to the bee; it can literally jump onto the bee and cling electrostatically to its hairs.
Electric charges play an important role.
When a positively charged bee approaches a flower, pollen grains can be attracted to it by electrostatic forces. In this way, some pollen may stick to the bee’s hairs even before it fully touches the anthers.
During the next visit, part of this pollen may be transferred onto the stigma of another flower.
Thus, electrostatics supports not only the search for nectar, but also pollination itself.
Flowers also “respond”
A flower is not a passive object.
It has its own electric field, influenced by air humidity, soil conditions, weather, the shape of the plant, and insect visits.
When a bee lands, a brief electrical change takes place between the bee and the plant.
This is a kind of invisible conversation:
the flower offers nectar, pollen, colour, and scent;
the bee carries an electric charge;
after the visit, the flower temporarily changes its electrical condition;
the next bee may use this change as additional information and understand that there is little point in landing on a less negatively charged flower. Of course, all of this happens unconsciously.
Not magic, but precise natural engineering
This phenomenon does not mean that bees “talk with electricity” in the way people talk on the telephone.
It is part of the complex system through which nature has made pollination more efficient.
A bee uses vision, smell, touch, memory, orientation by the sun, polarized light, vibrations, and electric fields.
The more we learn about it, the clearer it becomes that the small bee is not simply an insect flying from flower to flower.
It is an exceptionally sensitive living organism that reads the world in ways humans are only beginning to understand.
The shortest conclusion
Bees in flight build up an electric charge.
When they visit a flower, they can change the electric field around it. Other bees can sense this change and use it as one of the clues indicating whether the flower has probably been visited recently.
Invisible electricity is one more language in the ancient conversation between the bee and the flower.
