The Mothman Cometh?

Forty years after the unexplained incidents in West Virginia, the infamous Mothman was spotted terrorising the Goodacre family in North Carolina. This beauty was having a rest on our back door. It had a body length of at least two inches. I've never seen a moth this big before. I was half inclined to go outside and photograph its back, but was worried that if I open the door it might fly into the house. It's one thing if the cats eat the odd small bug, but I didn't really want them to have a go at this one.

A quick google search later told me that it was a Royal Walnut Moth (Citheronia regalis (Fabricius)). Apparently, this species can have a wingspan of over 15cm. I took this second photo to give you some perspective on the size of this moth.
