If you ever get close enough to a bee you might notice that they look kind of fuzzy. Their bodies are covered with many small hairs. These are actually called setae. The setae are very important to bees. They are like little sensors that aid the bee in things like determining wind speed. The setae are also important for pollination of plants. When the bee is in a flower feeding on nectar or collecting pollen to take back to the hive pollen often gets trapped on the setae. At the next flower it might come free as the bee wiggles in to take a drink and the plant gets pollinated.
