   Jeremy Tatum writes:  Apologies for showing yet another Winter Moth, but this one, photographed this morning at UVIc, is the first time I have seen what I believe to be Operophtera occidentalis  either at UVic or at my Saanich apartment.   It is maybe a couple of weeks since I have seen Operophtera brumata, and seeing this occidentalis today reinforces my suspicion that perhaps occidentalis flies a little later than brumata.

    Gordon Hart sends one from the Highlands.  I think it is O. brumata beginning to look a little bit past its “sell by” date.
