Two quakers

There was a slight flurry of activity here in Wolvercote, Oxfordshire, last week, with Green-brindled Crescent and Blair's Shoulder-knot both showing up (not surprisingly, as they'd been reported plenty elsewhere). I also finally got my first quaker species of the autumn on 20th October, and Red-line Quaker has shown up several times since. However, on the 20th, I think I also had a Yellow-line, a species I've not seen since. I attach a couple of photos, the first of the putative Yellow-line on its own, the second with that day's Red-line; I think they're sufficiently different to be the two species, but would be grateful if anyone could confirm.
