How Do Bees Communicate? Dance and Pheromones

How Do Bees Communicate? Dance and Pheromones

Imagine you know nothing about bees. You start keeping hives, and you notice three things:

Every hive has one queen bee.

Wherever the queen is, the other bees are.

When the queen is alive the colony is stable; the moment she dies, the hive falls into chaos and a large part of the bees abscond.

Based on human society, you reason: the bee colony must be a monarchy. The queen is the ruler of the hive. She lives in the center, issues orders, and commands the workers who forage, clean, raise larvae, and guard the entrance.

The ancients reasoned exactly the same way.

What the Ancients Recorded

Aristotle wrote in History of Animals that the hive has a "leader" that does not take part in foraging but supervises. During swarming and migration, all the bees follow this leader; if the leader dies, the hive falls into disorder.

Pliny the Elder wrote in Natural History that the swarm runs a governing system like a human city-state, with the queen as the ruler of the entire hive. When the queen goes out on her rounds, the whole swarm escorts her; once she dies, the entire colony dissolves.

The Chinese agricultural classic Nongsang Jiyao (Records of Agriculture and Sericulture) gives beekeeping instructions: in spring, the hives multiply; several queen cells may appear. Count them — strong or weak. If the colony can be divided into two, keep two queens and remove the rest. If it cannot be divided, remove every queen except the old one.

Across cultures and centuries, this "monarch" picture of the hive guided real beekeeping practice.

Since the colony is controlled by the queen, beekeepers reasoned, then control the queen and you will have endless honey every year. That is exactly what beekeepers did. And it worked.

The explanation was wrong. The prediction was right.

The King Has No Crown: Swammerdam's Anatomy

In the late 17th century, Jan Swammerdam dissected bees under the microscope and found the "queen" is merely a specialized egg-laying individual with no commanding power. But he could not explain how the colony coordinates without a monarch.

Then, in 1923, Karl von Frisch published his paper On the "Language" of Bees: workers communicate through dances. But which dance carried which message remained unclear.

After decades of painstaking experiments, he finally decoded each dance and published The Dance Language and Orientation of Bees in 1967.

For this achievement, von Frisch received the 1973 Nobel Prize in Physiology or Medicine.

When a bee circles in place in a small round dance, the food source is close — within 50 meters. When the bee traces a figure-eight in the air, the food source is far — beyond 50 meters, and the angle of the waggle run relative to vertical points the direction relative to the sun.

Then Why Does the Queen Matter?

If the workers talk to each other directly, and the queen does not command anyone, why does the colony stay calm while she is alive and fall apart when she dies?

In 1950, Callow and Johnston (working with Butler's group) isolated a substance from the queen's mandibular glands. It suppresses ovary development in worker bees. This is what we now call a pheromone.

The queen continuously secretes this pheromone. When it is plentiful, worker ovaries are suppressed, and it broadcasts the signal: I am healthy, I can breed — you go forage, you go build comb, you go raise brood.

When the pheromone runs low, the workers understand: the queen is dying and can no longer reproduce. They select young larvae hatched from fertilized eggs, build special queen cells, and feed the chosen larvae royal jelly continuously to raise a replacement queen.

So the "queen" is herself a product of the workers' selection. Her only job is to reproduce. There is no throne, no command, no monarchy — just pheromone chemistry and a dance language the size of a worker's body.

The Lesson of the Beehive

For more than two thousand years, from Aristotle to medieval beekeepers, humans managed bees brilliantly by following a wrong theory. The practical prediction — control the queen, get the honey — was perfect. The mechanism turned out to be chemical, not political.

The old explanation was spectacularly wrong. The old prediction was spectacularly right.

That is how the beehive taught science one of its most useful lessons: a good story is not the same as a true mechanism — and sometimes the two diverge for centuries before anyone notices.

The same patience lives in the microscopic world: a wing is not a blank surface but a network of veins, each ridge a record of flight mechanics — visible only under a microscope. With WWAI, you can see them the moment curiosity strikes, including an insect forewing specimen where the venation pattern and wing structures are clearly visible.
