Can bees hear?
Short answerIt depends
Not in the way we do. Bees have no ears and do not respond to sound-pressure waves the way a vertebrate ear does. They detect the movement of air particles very close to a source, and vibration transmitted through a surface, using Johnston's organ in the antennae — which is enough to read a waggle dance in the dark.
Two different physical quantities
Sound has two components: a pressure wave, which travels far, and the back-and-forth movement of air particles, which falls off rapidly with distance. Vertebrate ears detect the first. Johnston's organ detects the second, which is why bee communication by vibration works at a few centimetres and not across a room.
What bees do detect
- The air jets and comb vibration produced by a waggle dancer, read by followers pressed against her.
- The stop signal and the shaking signal, delivered by direct contact.
- Queen piping, transmitted through the comb.
- Substrate vibration generally, including a beekeeper knocking the hive, which is one reason smooth handling matters.
