Thanks to urtica for assistance with the taxon.
I saw this moth on top of a gasoline pump today. Gas stations tend to attract moths at night due to their bright lighting around the pumps. When day breaks, the moths find a place to rest.
This one looks like he's had it rough. It's missing scales near the end of it's wings....perhaps from flying into the lights all night? Most pictures I've seen of this moth show it in a similar condition.
Anyway, you can see that the wings are actually transparent when the scales are removed. The scales do not grow back.
