Queen Bees are unique in that there is only one per hive. The queen is fed Royal Jelly which is a sugary paste made by worker bees. The royal jelly allows the queen to become reproductive and queens can lay about 1,000-2,000 eggs per day. That's a lot of work! If you look closely in a hive, you can distinguish a queen bee by the large abdomen she will have. All worker bees are female also, but they have underdeveloped reproductive capabilities. You can distinguish a worker bee by looking for the pollen sacs on her legs.
