Among other nice things at the window last night (such as a gigantic long-horned beetle with antennae over twice its body length), was a Luna Moth.  This is about 2 months after their peak flight time, and I don't remember ever having seen one before after mid-July.  It was quite fresh, and obviously hadn't just survived all that time - the adults, I think, live only a few days anyway.
