Two more pics of this moth yesterday. It was just over half inch (5/8*) long. The underwing was a off white with a pale greyish fringe, bit like black rustic but fringe more pronounced. I know the reniform stigma has a whitish edge, not unlike cabbage moth, but the absence of any pronounced subterminal fascia which all the cabbage moths I have seen, has been strongly present - in this moth it doesn't show up well, if at all. I must admit I cannot for the life me see why I called it a Brindled Green - although I did the trap after a night shift! Any suggestions welcome.
As for this am, only real surprise was banded Riband Wave and my first Blair's S/k.
