I never saw one of these and didn't know what it was! They hover and feed like a hummingbird, hence the name. Kind of looks like a shrimp with wings!

Check out these photos.
This is a Hummingbird Clearwing. At first I thought it was a bee of some sort and I took photos of it and researched it. It is in the moth family. Pretty neat.
