Do bees have ears?
Can bees hear?
How do bees pick up sound?
No, bees do not have ears, however, they are able to pick
up sound, so yes, in a sense they can ‘hear’ but not through the use of ears.

How do we know that bees can detect sound?
Several research experiments have confirmed this.
In 1989, researchers Towne and Kirchner managed to train
bees to leave a feeder in response to a sound signal, and in order to avoid a
mild electric shock.
Later, in 1991,
Kirchner et al trained bees to turn left or right as they entered a feeder,
depending on a sound signal.
So if bees don’t have ears, how do bees detect sound?
So far as scientists can make out, bees may use:
- The antennae – actually, a very particular
part of each antenna. In honey bees,
there are a collection of sensory cells (called the Johnson’s organ) that are
sensitive to vibration (remember that sound waves are basically vibrations),
and they are found in the second segment (called the pedicel) of each antenna.
legs – In honey bees, sound vibrations are picked up by organs in the legs,
called subgenual organs.

How do bees
use sound information?
bees perform their famous waggle dance, a dancing bee waggles her abdomen and
vibrates her wings.
vibrations and sounds she creates are then detected by other members of the
colony, (Michelsen et al. 1986a; Dreller and Kirchner 1993a; Michelsen 2003),
such that she is able to transmit important information to the other bees.
Sound is important in honey bee communication. Honey bees
use a range of piping and buzzing sounds in the nest that are picked up by other bees, and are used to communicate and affect behaviour of the colony.
For example, a small group of experienced
forager bees called 'nest-site scouts' produce a "piping-signal" that
primes the workers for swarming (Rangel, 2008). You can read more about this on my page about how and why bees buzz.
