My grandmother found this in her backyard near Chardon, Ohio. Looking through your site I found that it is a Polyphemus Moth. From the ruler I put next to it it is 5-6 inches across. It’s wings were not perfectly flat when I took this. My kids (5 & 3 years old) went wild at the "huge bug"… they enjoy your site immensely!
Thank you for sending in you Polyphemus Moth image. We have begun receiving identification requests again for the second brood, and your photo is a welcome addition to our homepage right now.
