A hive of bees consists of workers, drones and a queen bee.
There is usually only one queen bee in a hive and she's larger than the other bees. She can live for three years or more and is the only one that can lay eggs.
Drones or male bees are so called as they make a low droning noise and stay within the hive, only venturing outside to fly on a very warm day.
Worker bees are female and they stay in the hive until they reach twenty days old. During this time they produce beeswax, feed young bees and keep the hive clean amongst other duties. As they grow older they travel out into the surrounding area, looking for and collecting nectar and pollen to bring back to the hive.
