As a rookie beekeeper I do worry about the bees in such a big snowstorm, but honestly they are probably fine. I just can't help but think about them.
"I have read up on their astonishing winter habits. Bees metabolize the dense carbs in honey ferociously, generating heat, which they further augment by flexing their flight muscles, without moving their wings. Clustering around their queen to retain the heat is their means of climate control. Deep in the hive, the cluster expands and contracts with the temperature; the colder it gets, the tighter the huddle.
But can these cluster physics really maintain a constant central temperature of 70 degrees in a pelting snowstorm? “You bet they can,” said Leslie Huston, a Newtown beekeeper. “And in late January, if they have begun producing brood for the spring, the activity can raise the temperature to 90.” -NYT article here
