Colonies are made of wax cells. There are three types of bees in a colony. This is a queen bee. She is the biggest bee. There is only one queen in a colony. She lays the eggs. This is a drone. Drones are male bees. Their main job is to mate with the queen. This is a worker bee. Worker bees are female. They build the colony and they clean it too. They look after the young bees. They make honey with the things they collect from flowers. From egg to bee The queen lays eggs in the cells. There are three different kinds of cells: for the new queen, for the drones and for the workers. After three days, the eggs hatch into grubs. The grubs grow a head and a body with two parts. They grow six legs and four wings. Then the young bees come out of the cell. The three types of bees have different development times. It takes about 16 days for a queen bee to grow from an egg to an adult. A drone takes about 21 days and a worker bee takes about 24 days. While-reading Read and understand different bees’ role and development time. lay eggs about 16 days mate with the queen about 21 days build and clean the colony, look after the young bees and make honey about 24 days Read and understand the life cycle of bees. While-reading Read and understand the life cycle of bees. While-reading Post-reading Post-reading Read and decide whether the following statements are true or false. All colours are visible to bees except blue. Bees have 5 pairs of eyes and 6 legs. Honey bees are skilled fliers. They beat their wings 100 times per second as they fly at a pace of about 25 km/h. As she builds her colony, a honey bee queen may lay up to 200–300 eggs every day. Honey bees form a “winter cluster” to stay warm throughout the winter. There are more than 2,000 species of bees in the world. Bees’ wings beat about 12,000 times per minute, which is why they make so buzzing noise! Honeybees can sting someone twice. Someone who looks after bees is called a beekeeper. F F F F F Post-reading Read and decide whether the following statements are true or false. All colours are visible to bees except red.
