I thought of N. ferruginea immediately -- it is the common species where I live -- but thought you must have some similar species in Europe. Now I see that N. ferruginea has been recorded from Spain and Portugal and is distinguished from native species by "the orange-brown stripes on the dorsum in place of the more usual black markings."

I think vein Rs might be too long. A clearer picture of the wing would help resolve that doubt.

I think there was a revision of the species group including ferruginea but I don't have time to look for it right now.
