Polyphemus moth

Found this stunning Antheraea polyphemus a few days ago at the high school. Prime condition male it seems, probably emerged on the same day since there was trace of meconium. This is a member of the silk moth family, but I doubt it would be very beneficial commercially. I've seen wing remains of this species before in Canada (evidence of bats usually) but this is the first one I've seen alive so that was nice. The biggest moth I've seen in the US so far.
