No, bees do not have ears, however, they are able to pick up sounds, so yes, in a sense they can ‘hear’ but not through the use of the ears.
Several research experiments have revealed this.
Researchers Towne and Kirchner (1989) managed to train bees to leave a feeder, only when a sound signal was given, 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 far as scientists can make out, bees may use:
At the time of writing this page, it’s not clear how bumble bees or solitary bees pick up sounds.
When honey bees perform their famous waggle dance, a dancing bee waggles her abdomen and vibrates her wings.
The vibrations and sounds she creates are then picked up 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.
use a range of piping and buzzing sounds in the nest that are picked up and
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.
