Hummingbird Moth

I was in a multi site meeting at work this past week and for some reason these little guys came up in the discussion.  Sightings in Wisconsin and Minnesota and I have seen them here in Missouri a few times.  I was really surprised when I saw one at my flower boxes this morning.  It stayed around long enough for me to get the camera.
