Confidence: It's likely to be this, but I can't be certain.
Notes: Not much recorded around here. It was posted on a moth forum and the consensus was the suggested species, apologies for the quality of the image but this is a small crop from a photo of an emperor moth which was to the right of this one. It ws the first moth photo I ever took and this moth was only recorded by accident. It was recorded in a mixed conifer/deciduous plantation on a moorland.
