Common Wainscot (Mythimna pallens)

Observation - Common Wainscot (Mythimna pallens). Description: Attracted to light left on overnight. I'm pretty sure that it's a Wainscot (Mythimna) but which? Unfortunately I didn't get a look at the hindwing. I thought at first it might be a Smoky Wainscot (M. impura) but the location - near Edinburgh - makes that

Attracted to light left on overnight. I'm pretty sure that it's a Wainscot (Mythimna) but which? Unfortunately I didn't get a look at the hindwing. I thought at first it might be a Smoky Wainscot (M. impura) but the location - near Edinburgh - makes that unlikely so I'm guessing Common Wainscot (M. pallens)
