Leaf or Not?

Doesn't this look like a crumpled leaf that just got stuck on a screen?  
We were on a camping trip, just registering, and I was taking a picture of a bug on the front window.  The ranger said, "If you like taking pictures of things, come see this" and brought me round to the side of the guard shack.  
This is a moth, not a leaf!  Amazing enough on its own.  How can it fly with those crumpled-up wings?  But now look at this view from the side:
What looked like 3-D crumpled wings are really flat wings.  What an illusion!!!
That was  my marvel for the day.
