the bee's knees and more

Back in the day, the term "it's the bee's knees" meant something was sweet and good - presumably because the pollen collected there maintains the colony that makes honey. It is the nectar that bees consume that actually becomes the honey. But I digress...
I chose the title today because this bee not only carries the pollen on its knees, but is a true overachiever carrying the pollen the length of its leg and underbelly.
Wow!
