Why Do Bees Make Honey?
Honeybees are special in that they over winter as a colony unlike wasps and bumblebees. The colony does not hibernate but stays active and clusters together to stay warm. This requires a lot of food stored from the summer before. Although a hive only needs 20-30 lb of honey to survive an average winter, the bees are capable, if given the space of collecting much more. This is what the beekeeper wants them to do. Bees have been producing honey the same way for over one hundred and fifty million years.
