We found this "thing" on the window of our office this morning and there is some discussion as to whether it is a moth or butterfly. Its body is approximately 2 inches long and its wing span is approximately 4-5 inches wide. The picture makes it look darker then it is. It actually is a medium shade of gray with orange and white accents.
What a wonderful image of a Cecropia Moth, one of the Giant Silk Moths or Saturnid Moths.
