This species, Anatis lecontei, is fairly common in the certain places of the Rocky Mountains. I found this one up American Fork Canyon (Utah) a couple of weeks ago. It's hard to to get a good sense of scale but it is about 4 to 5 times bigger than your common lady bug. The shadow also obscures a black band that encircles the elytra. It's a handsome creature. The habitat shot is up Tibble Fork Canyon.
