How Do Bees Communicate the Location of Flowers?
蜜蜂如何告诉同伴花蜜的位置？
-
Honeybees perform a ‘waggle dance’ on vertical honeycomb surfaces to share precise floral coordinates.
-
The angle of the dance relative to vertical indicates the sun’s position, guiding flight direction.
-
The duration of the waggle run tells other bees how far to fly—longer waggles mean greater distance.
-
Dance intensity and repetition rate signal flower quality, helping scouts prioritize better sources.
-
Bees detect polarized light patterns in the sky, allowing navigation even when the sun is hidden.
-
They also use landmarks, odors, and memory to refine their routes during repeated foraging trips.
-
A single successful dance can recruit dozens of workers within minutes to a rich nectar site.
-
If food is very close—within 50 meters—they switch to a simpler round dance instead.
-
Researchers have decoded these movements using high-speed video and robotic bee models.
-
This communication system evolved over 20 million years and remains one of nature’s most sophisticated languages.
