Thanks emg, it looked more like a feathered to me but i felt that it was missing the spot on each wing??
I have to say I'm completely undecided on this one so it would be interested what anyone else thought about the two offered so far? I personally would lean towards feathered but can't commit 100%???
For what its worth I agree with emg as well, as you pointed out the scalloped wing shapes missing, but as you say the dots are not prevelant but with this wing shape thats about all it can be. So anyway my vote is Feathered Thorn
I too hesitated over the absence of spots on the wing, in my book the description has 'variable markings' and 'often with a small silvery spot near wing tip', I went to check a few sites and found they don't always seem to be present, there are some photos here: http://www.norfolkmoths.co.uk/index.php?bf=19230&photoid=1184110078 where the spot is absent, see what you think when compared to yours, it may be something else but hopefully this might help,
