One-eyed Sphinx Moth Camouflage

She really has two eyes. But hidden under each forewing, each hind wing has one beautiful blue eye spot surrounded by black eye-liner and a brush of blush. In spite of this splash of color, she can all but disappear on tree bark just by covering her hind wings. Potential predator? Just uncover the hind wings and flash the eyespots. Pretty clever, eh? These native moths are fairly common across most of North America, and their caterpillars feed on poplar and willow.
