A petite blue butterfly (Euphilotes sp.), on western blue flag iris, at Keyhole Sink. There are about twenty species of blues occurring in Arizona, and most of them (to my eye, at least) look exactly the same. Whatever diagnostics set them apart are beyond my small skill to recognize.

Greater short-horned lizard (Phrynosoma hernandesi), spotted along the Keyhole Sink Trail, Kaibab National Forest, Arizona.

This plump little lizard was only about 2 inches long (5 cm) from snout to vent, with very little length added by its stubby tail. We both decided to lie on our bellies for this photo shoot.
