Reddish bar on forewing

Thanks for looking at this one and the observation about the distinctly reddish bar. The book I use (Field Guide to the Moths of Great Britain and Ireland) does show the Red Twin Spot Carpet with a darker reddish bar on the forewing but it also states in the text that it is very similar to the reddish banded form of the Dark-barred Twin-spot Carpet and goes on to mention the distinct notch on the inner edge of the broad dark central forewing cross-band near the leading edge. The specimen in the picture does seem to have this notch although the wings are at an angle. I would be grateful for any other views on this one as I would like to be sure I understand what separates the two species if that is possible.

Difficult

I recall some work recently that showed that the notch was not completely reliable. Nevertheless, this is likely to be Dark-barred.

Red or Dark-barred Twin-spot Carpet

Thanks to all of you for these clarifications - it is very helpful to be able to have this type of discussion. Because I am still relatively new to moth identification I am still tending to think that what the latest books say is definitive but of course research is moving things along all the time.
