Spotted Tussock Moth - Lophocampa maculata

Just about everyone has seen these little guys crawling around in late summer. They feed on the leaves of poplar, willow, alder, birch and maple and if you touch them they roll up in a ball. The moth, on the other hand, is a little trickier to find. They come to lights, which is where I found this guy one morning. It was on the wall by the front door.
