This is a Measuring Worm Moth or Geometer in the family Geometridae, and that name comes from the movement pattern of the caterpillars, called Inchworms or Measuring Worms. We believe your individual is a False Crocus Geometer based on images and the range map on the Moth Photographers Group. As you can see, the spotting pattern on the wings is quite variable. The species is also pictured on BugGuide.
