Bug of the Month

When I looked out the front door this morning, I noticed something sticking out of the side of the house by the garage. It looked like a leaf, but when I got closer, I found this:
One of the prettiest things I've seen (which is a nice surprise from all the nasty-ass bugs we've seen!).
I'll have to do some research and see if we can figure out just what it is.


Update 6/21. I think it is a Promethea Silkmoth:I found it here.
