Honeybees（蜜蜂）are great dancers, but they don't just dance for fun. Dancing is also their way of communicating. The bee dance is called the "waggle dance"（摇摆舞）.
Waggle dance helps bees find food. If a bee finds something to eat, it will start dancing. First, the bee's position shows other bees which way to go. Second, if the bee shakes a lot, that means the food is far away. Less shaking means the food is closer. Third, if the bee dances for a long time, it means the food is very delicious.
A research team studied honeybee dance moves. The scientists are from the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences（中国科学院西双版纳热带植物园）. They found out how bees learn the waggle dance. Young bees learn from older bees.
The scientists recorded videos of bees in a laboratory. Then they compared two groups of young bees. The bees were only 10 days old. In one group, young bees could watch older ones dance. These young bees became good dancers. In the other group, young bees could not watch older dancers. These young bees could not dance as well as the first group.
This study changed how scientists think about bees. They used to think all bees could do the waggle dance without having to learn it. Now they know young bees learn it by watching the older ones.
