Nant-y-bai Mill

I trapped at Nant-y-bai Mill last night, just below the Lead mines. Had a really interesting catch, the usual Common Quakers , Small Quakers, Clouded Drabs, Twin spotted Quaker, Oak Beauties and Dotted Borders et al.
Plus a Red Sword-grass, 2 Yellow Horned, a Shoulder Stripe which is so lively I'm finding it difficult to photograph,what I think may be a Pale Pinion , but it is very battered and I'm probably way off the mark, and a dark pug of some sort. Is it a melanic form with the very dark body???

 Red Sword-grass

Pug?????? wing Length 12/13mm
Thanks for all help.
