When a forager worker returns to her colony, she may carry out a
special behaviour called the waggle dance. She vibrates her abdomen from side
to side while walking forward one step. This is known as the waggle run. She
then turns in a semicircle and walks back to the starting place to repeat the
waggle run, this time returning to the starting place by turning in the opposite
direction. The dance is detected by a few nearby dance follower bees. These
are unemployed foragers or young bees about to begin their foraging career.
