I’m sure I read somewhere that bees consume less resources over winter if the days and nights are colder rather than milder. Does anyone have any figures for the temperatures at which bees become less mobile and cluster more? Are we talking about daytime/nightime temps below 10 degrees, 5 degrees or lower?
I just want to have a sense of how they are doing if the winter turns out to be colder or milder, and what this might mean for springtime.
