I’ve lived in the Twin Cities for 45 years and only today saw one of these cleverly camouflaged creatures on our window presumably sheltering from rain. It looked like a folded leaf! Its body was about two inches long, and it was walking vertically on its six legs, which seemed to have suction cups at the ends. A quick Google search revealed it to be a broad-winged katydid, a common insect in this area.
