Thanks for all responses, and to expand further on the question I can’t properly ask, mainly because I don’t understand.
I’m trying to understand when and how foraging bees decide to bring home pollen or nectar.
As pollen is necessary for bee production by the queen. Bill Anderson - a self described ‘Idle Beekeeper’, if such a thing exists, says in his very readable book (page 113) that the Queen need protein to lay eggs.
So, would foragers bring home more pollen early in the season to support colony growth? And would they subsequently focus on bringing home nectar after pollen?
I’m still confused as to the ratios of pollen and nectar which are brought home. The foragers must respond to a need, so how do they do it, and how do they know how to do it?
Second year of beekeeping.
There's a lot to learn, more to understand, and all, to try and remember the next day.
