Creepy Bug

Today I was washing dishing talking on the phone ( No surprise right),I kept looking outside at this leaf on the chair. After some time I noticed that this leaf looking thing was moving. Now I know it was not a walking stick but what was it. Was it really just a leaf blowing in the wind or was it something else. As I got closer to it I noticed it was this really creepy bug. I have never seen a bug like this before. I can not believe it but I had not. I have been searching and Searching but I can not come up with a name for it. It sits on what looks like a grasshopper body and the body is covered with two wings that look exactly like a small leaf. It has long long antenna's. Can anyone help?
