The wind was very blustery (why it was clinging to the screen on the window, I'm sure), hard enough to affect my steadiness, so this isn't quite as crisp as I'd like. But it's a pretty little bug with two little "horns" on the head and that lovely mottled color. We had a spectacular "hopper" on a bush in the schoolyard when I was in 4th and 5th grade: metallic green with a sort of spine on its back that was red on the tip. We used to grab them by the "spine" and they'd release a stream of liquid that (being kids) we were sure was urine. They were all over that particular bush--never saw them elsewhere--and nobody seemed to know what the bush was. It was destroyed to build a gymnasium in that space.
At any rate, this little guy was halfway up the kitchen window (small window over the sink) and I was standing at ground level below--it was above my eye line and this was the best picture I could get.
