   Jochen Möhr sends a photograph, from Metchosin this morning, of an Operophtera suspected to be O. occidentalis.  Jeremy Tatum writes:  I agree, I think this is very probably occidentalis. The middle terminal cell is only slightly – but nevertheless distinctly – darker than the adjacent cells, and I believe that this marks it as occidentalis. I dare to label it such without a “probable” qualifier!  Keep a look-out for winter moths with this darker cell!
