Tenodera sinensis
As you probably guessed from the name, this is an import. It was brought to North America in the 1890s, and has stuck around since then. It's the biggest mantis you're likely to find. I see them all the time now, though I never seemed to notice them before.
Lat: 42.20, Long: -88.97
