While mowing this weekend in some very nice 80 degree weather, I noticed this single tiny bee pollinating every flower he could find. You can see him near the bottom in this next photo.

He was buzzing into one of the small flowers, moving around a bit, then buzzing away to another open flower on the same stem.

He was working on half the garden when I started mowing and he was still working on the other half when I was done. And all by himself. Pretty impressive.
