My measurement is more or less nose to wingtip. One week a couple of these showed up on the same wall. They were tucked in between the bricks, so I had a hard time getting things like focus/lighting/angle to work out, but here they are any way. The one is more worn, but they are close enough in appearance and came at the same time (the only time I have seen them) so I wonder if they are the same species. (May be the same moth)
