Hi Gene & All

Someone mentioned (Pete I think) that the difference in daylight in  
November, December and February is minimal.  The difference, however,  
is that in November and till Dec 21 the day to day daylight is  
declining(here in the northern hemisphere) whereas from Dec 21 through  
February it is increasing.  The daily ratio of light to dark will show  
double the difference n'est pas.  As we don't think like bees and  
certainly vice versa, maybe they can act on increasing or decreasing  
ratio of light to dark.

After being a beekeeper for 40+ years but still being a novice when it  
comes to things I see in the hives and learn from Bee-L etc, I am  
amazed by the number of issues that are not understood by both  
scientists and beekeeping professionals.
