Have to wait for our expert Roger to advise. In the moth world there are so many lookalikes that will make you go .
Anyway, I always wondered where the term "daylight moth" came from. I noticed that some photogs started it at NPS and CS and then it continued.
As far as I remember, it's always been "day-flying moth" to describe generically, this group of moths that fly during the day instead of at night, which the majority of moths typically do.
You managed to get a clean and green bg shot.
I suppose their wings were not on the same plane resulting in some parts of the wings not sharp - tough situation for you.
I was lucky. the moth was spreading it's wings flat and i took a shot from above. The chinese words says "The October of 2008 [lunar calender] was extremely rainy and on the first non-rainy day i captured this shot of the day flying moth." [rough translation].
