Species with which Square-spot Rustic (Xestia xanthographa) interacts

I think Rob could well be right, but the moth doesn't look all that worn to me, so if it is a Bright-line Brown-eye it's a very odd one. Can't think of a better solution though!

Could it be a Common Rustic

Could it be a Common Rustic or Lesser CR Martin? Its a fresh looking moth I agree.

It certainly seems very fresh to me with a strong undamaged fringe of cilia on the wings. Looking through my collection of images of (Lesser) Common Rustic I cannot see any that have this feature.

Square-spot Rustic, which is still my best guess, might have something close to this - a picture at http://www.ispot.org.uk/node/297389 shows this somewhat.

Of course for this sort of feature it is where having a proper collection, rather than just pictures, would really pay off.

Point taken re Square-spot

Point taken re Square-spot Rustic David, certainly not either Common Rustic as I suggested above and I cant see any features that make me think its Bright-line Brown-eye. After having a close look at this one and a good look at the other dark undeniable Square-spot Rustic youve posted I dont think this can be anything else.

All the features for SSR are there in this dark specimen as far as I can see.

Line of dots

The other feature which is good for Square-spot Rustic is the cross-line of black dots following the post-median fascia. Don't think either Bright-line Brown-eye or either of the Common Rustics have this, but would have to check through a lot of pics to say 'never'.

BTW I think David's point about a 'proper collection' is nonsense for features like these which are clearly visible on moth forewings. Hind/underwings and bristles on flies maybe, but the hundreds of excellent photos from a wide range of localities available at the click of a mouse are going to be way better than the most comprehensive collection can ever be. Which is good, because they way mothing is going, it is just as well that not all of us have to keep drawers full of dozens of moths of every species just in case.

And in discussions like this, the postage could get a bit steep...

Yeah Jamie the row of dots is

Yeah Jamie the row of dots is quite clear when the image is viewed in full size, as are the stigma which at first glance arent as obvious as usual.
