Honeybee thermo-videos in winter and summer + Homeostasis

In this video you can see how bee heat the cluster. You can also notice that the ambient hive temperature goes down to -15'C demonstrating clearly that bees DO NOT heat the hive it self but the wax comb within the cluster. Wax comb is great at retaining heat which radiates back at the bees. Smart indeed.

In the second video you will see the bees in summer
