Description:

Pale moth in daytime besides Gordale scar on limestone (presumably). See second image where I've taken brightness and highlights right down, so faint but definitely kinked cross lines can be seen.

Hi Cardiff Boy, Grass Wave

Hi Cardiff Boy,

Grass Wave might be one possibility. It does seem to be quite worn, the markings are very faint.

definitely a geometrid but not, i think grass wave

Thanks for suggestion. The moth was about that pale on the day but image may be slightly over-exposed. If I edit the image and take brightness right down, there is definitely one, and I think two, cross lines. And the innermost/first cross line is quite kinky, not like the smooth curve of Grass Wave (I'm basing this on field guides and on-line pictures).

In some ways, more like a very pale Clouded silver? But can't see those black dots on the forewing, there are some possible dots but not in right place. And flight season is wrong.

I've attached this second version of the image .

Hi Paul, I think youre right

Hi Paul,

I think youre right re the crosslines being too kinked for grass wave. I'd maybe expect more crosslines on it also. Certainly 2 lines that are readily visible there. Its not going to be a straightforward one -for me anyway. It doesnt cry out Clouded Silver but then again its not in tip top condition so cant rule it out either. Those 2 lines towards the rear of the forewing should be the key to this one.....

I think it may be a worn

I think it may be a worn Clouded Silver. Late in the season they often lose all of the dark markings, including the discal spots, ending up completely white and impossible to separate from their congener White-pinion Spotted which can also fade to plain white. If you compare the faint pair of lines still visible near the termen you can see that they are a good match with Clouded Silver’s markings.

Thanks DD

I thought it was a good match except for the spots and couldn't find any photos without these. Your personal knowledge strengthens the possibility. It's supposed to be 'well established in Yorkshire' although flight season is to 'early July' and this was mid July.

Habitat of bare rock isn't perfect but trees etc not far away.

Hi Paul,

I don't think mid July is a late date for Clouded Silver especially as we had a cold spring which delayed the emergence of a lot of species. Looking at my notes for 2013 my last CS was caught on July 27.
