Bumblebee Buffet.......

I have a large crop of monarda this year.  The bumblebees are everywhere.  I have taken a lot of shots but none of them seem to be in focus. Last evening I was out with the macro setting on and stood right against the plants.  It was a feeding frenzy.   I never noticed before that they are scraping the underneath the petals of this flower.

As the flowers matured they seem to be getting darker in color. I don't know how much longer they will stay in bloom but when they change they become a dead looking dark brown.
