Can you help I’d this bug? It has been resting for a day over my neighbor’s door. It’s about 4″ wide and brown. We live in Cincinnati. The date is mid August, 2014.
This is a female Polyphemus Moth from the family Saturniidae, and like other members of the family, adult Polyphemus Moths do not eat. They only live long enough to mate and lay eggs, surviving on nutrients stored while a ravenous caterpillar. Hopefully this female has mated and she will lay fertile eggs.
