There she was, perched smartly on top of a sage flower. Then, off she flew. I waited for a moment, because these bugs have a tendency to fly around a little and then land back in the same spot.
Sure enough, she came back to a flower just inches away. It looked like her mouth was moving. After I took her picture, I could see that she was chewing on a little bug of some kind. Guess she just left to get a quick snack.
