The namesake "blue devil" of this site is fully grown at 5-8 inches, has a bright blue tail as a juvenile, an identifying "Y" pattern on its head and back, and is inclined to do a quick set of push-ups when disturbed. At the edge of its range in Minnesota, the common five-lined skink is the rarest of our three lizard species, this site hosting one of the state's largest known populations. The granite outcrop here that the skinks favor for basking-a key habitat element used to regulate body temperature-is itself an increasingly rare natural feature.
