What is This?

I spotted this little creature on our back door this morning and I just had to take a picture of it. Isn't nature wonderful? Look at the detail on him! I have no idea what kind of insect it is.

Orange and Black Moth

I managed to snap this picture before he (or she) flew away! I googled moth images, but I couldn't find out what kind of moth this is. I have since done some more research and I found it! It is a Red Admiral (Vanessa atalanta).
This photo was taken in our backyard.
