Only one bumblebee survives the winter from any given nest. That survivor has to be big enough to not only survive hibernation, but raising the first generation of workers when there isn't much in bloom yet.
I felt rarely privileged to be in the right place and the right time. I was so excited and happy, in fact, that very few of the pictures turned out. Hah! Herewith, five not very good photos of a bumble bee queen.
