Bees


Florida has more than 250,000 bee colonies. Half of them are moved to the northern states in the summer. Florida is one of the nation's top producers of honey. Bees must know a lot about geometry. Their honeycombs are perfect six-sided cells. In winter, bees flap their wings inside the hive to keep it warm. The hive can have a temperature of 91oF to 97oF. Bees that find food (nectar) return to the hive and do a “waggle” dance. This dance tells other bees the distance, direction, quality and quantity of food at the nectar source. Worker bees are all female. They can fly as far as 3 ½ miles from their nest to find food. Their top speed is 15 mph. A typical bee colony contains 20,000 to 30,000 bees. In one year, a colony can collect more than 260 pounds of nectar that will be converted into honey.
What would happen if honey bees disappeared? What percentage of the agricultural crops produced would we lose? What types of Florida commodities would become unavailable as a result?
