Have you ever seen a bee fly busily？Do you think the bee is just flying around？Actually，the bee is hard at work.
Bees spend a lot of time looking for food.But not all the bees in the hive（蜂巢） have this work.Bees can be divided into three kinds—a queen bee，drones（雄蜂），and worker bees.The queen bee is very important.She is the mother of all the bees that live in the hive.Worker bees do all the other work in the hive.Besides looking for food，they make and clean the hive.They also take care of the queen and protect her.
Bees make dance-like movements inside the hive to send messages about food.They use different movements to give different kinds of information.They tell where food can be found and how far away it is from the hive.Bees can even share how much food there is and how good it is.
And surprisingly，a new research has found that a group of bees could generate an amazing amount of electricity by beating their wings more than 200 times per second.And the amount of electricity could reach 100 to 1，000 V（伏）.That's eight times greater than the electricity a storm cloud can produce.
Scientists found that the denser（密集的） the cloud of bees is，the bigger the electrical field is.Based on these findings，the team recorded that bees—which group in huge，dense clouds—could have an influence similar to that of a storm.Further research is needed to find out how electricity influences the bees and their environment.
