Cyclophora dataria [Geometridae]

The colors of this inchworm vary in the intensity of contrast between light and dark markings. Colors range from tan brown to grey but always with the darker middorsal semicircle countered by the anterior lateral light markings, paricularly on A2-A5. This species is common on white oak during July and August.
