I’m not sure if the bumblebees even have active hives anymore. I doubt they do as there are almost no flowers left except for a these garden asters and a few tattered flowers elsewhere and that is not much for a colony to live on. Still, everyday when the temperatures get above 50 degrees the bumblebees are actively working their way across the masses of aster flowers gathering or maybe just eating one last meal of nectar and pollen. This might go on for another week but very soon even the daytime temperatures will be too cold for these worker bees and they will die. By then the new queens will have found safe hideouts in clumps of grass and leaves to wait out the winter. Perhaps this one is a new queen. Her wings are shiny not dull and ragged. Let’s hope the winter is good.
