Hi Mr. Farmer.

Honey is an insulator in a cold winter. To stay warm Honeybees form a ball inside the area that contains Honey.
If too much Honey is removed in the fall the bees can't keep the center of the cluster warm enough { with their body heat } to survive.
Same thing if too much Honey is eaten by the bees.
