I'm sorry I actually have the wrong size on there. Its only 1/2 inch across, not an inch and a half.
I wish I could have gotten a better picture (camera wouldn't focus) as its much more bizarre looking in real life than the photo looks.
Bugguide.net identified it as a wheel bug nest!
These are actually great bugs as I've heard, they kill lots of garden pests. Apparently these bugs hitched on the bandwagon after the Japanese Stinkbugs which invaded the U.S. around 2000 and have been attacking all kinds of fruits/vegetables. The wheel bugs, are now preying on the stinkbugs. Bizarre critters.
