It is enough, that I understand my region's conditions. And perhaps I understand after 60 years beekeeping.
Beebe, you do not even know, what kind of laboratorio researhes I have found from google, but you claim that they are worth nothing. When you see a reseach, you must conclude yourself, do it helps you to understand, how bees overwinter.
My bee's winter is 8 month long. Bees use only sugar as food from September to April. And pollen.
During 5 months they cannot fly out and cannot pick water. And bees do not dry up in their hut. They cannot drink condensation water from walls, like many say/know.
These are things, what most wise guys cannot even imagine. And then some beginners come to debate with me, that I do not understand about winter.
