What is This UFO?

Pardon the poor quality of these shots. I saw this creature in the flowers and fired off a few panicky shots before he zipped away. I have never seen one of these before. He was about the size of my little finger. It darted about like a mini hummingbird but I guess it's more moth like? ( A couple more shots are in comments - sorry the focus is all off).

Any idea what this is?
