Well... not quite but a little movie nevertheless. I went to the garden today and noticed one of the white bees on a flower. I watched and observed it dedicate minutes upon minutes on one single flower. Eventually I realized that perhaps I would have time to go back, get my camera, and do a little video recording.
I left, came back, and the bee was still there on the same flower. Here is a little sample of its behavior. It was a windy day so things moved around a bit. Sorry for that.
