A busy bee is an idiom that refers to a person who is active or busy.
In a bee colony, there are three castes: the queen bee, worker bees, and drone bees. Worker bees, the ones referred to as busy bees, have several duties to the hive including collect food, build the nest, clean cells, guard the hive, and build wax. They are the smallest in size.
