Your letter to the bugman:  Large is relative, I suppose.  This was about 1.25 inches long. Doesn’t sound big but it’s a lot larger than any other moth I have seen around here. Thanks.

Male Io Moth

Dear Pk,
This is a male Io Moth, one of the smaller of the Giant Silkmoths that are native to North America.  Like many members of the family Saturniidae, Io Moths have large eyespots on the underwings that enable them to frighten predators.  Here is a BugGuide image of an Io Moth with markings similar to your individual.

Thanks!   I wondered if there was more to the wings than it was showing.  Now that you have explained “Underwings” I will be a better moth identifier.  Might even try to intentionally startle a moth to see those eyes.   Thanks a lot!
