This marvelous large moth (Hemaris thysbe) has been on my anise hyssop for the past couple of weeks. It looks for all the world like a tiny fairy-like hummingbird:
It moves pretty fast, so it wasn't exactly easy to keep it in the camera's field...sorry. The end of the video has the best shots of it.
It amazes me how quickly it gets the nectar from each flower- it's tongue must be lightning fast!
