This moth was on the steps outside of our building at the Great Lakes Naval Base about halfway between Chicago and Milwaukee. It was huge (almost the size of a small hand). Can you tell us what species it is?

Male Polyphemus Moth

Hi John,
You can tell this Polyphemus Moth is a male because of his well developed antennae.  We hope you had an opportunity to view him with his wings lying flat because then you would understand where he got his name.  There is a large eyespot in the center of each lower wing, and though the moth has two eyespots, one on each side, it was still named for the monocular cyclops from Greek mythology, Polyphemus.
