Yes, this species varies greatly between specimens in the amount of white showing in the forewing, hence C. 'heteroleuca', I suppose.

Well spotted Ian. It looks very good. I think I had ruled it out as it was an Alpine species - I should have looked more carefully at the location !! Well, we have got there in the end. Despite me taking us on an incorrect side-track.

Having recently identified the species, I thought it may be. C. persimilis (Similar Carpet) See:-

I agree it is tricky. I just could not find any Chrysolarentia sp. I felt it matched. It has the pale patch out to the forewing apex, with the darkish patch beside that sort of extending along adjacent to the termen/outer margin, with a pair/joined spots above that like many E. subidaria have. Also the long curved marks, almost forming a line along the termen. SOme Chrysolarentia sp specimens share these, being related. We might change our mind down the line ?
