An interesting find

As I was sitting at the computer tonight my usural friends the frogs were keeping me company on the window. All of the sudden I hear this noise like something tapping on the window. I look up and this guy if fluttering all over my frog friends. The frogs were not happy but they did stand their ground. It's hard to tell in this picture but this guy was about 4 to 5 inches from wing tip to wing tip. Tom called him a luna moth. I just thought he was too cool.
