Moth?

I have no idea what kind of moth/butterfly this is but it fell near my feet as I was moving my hose. I think it's a moth. So pretty and with such vivid markings. Anyone know the species let me know.

NOTE: I found out what it is, it's a member of the giant silk moth family. It's called a Polyphemus Moth and apparently mine is a female. The information said they only live a short time as an adult, probably near the end of her life when I found her. I'll check my aspen tree to see if there are a lot of little yellow caterpillars roaming around on it. Maybe they'll eat oyster shell scales, that would be super.
