   Jochen Möhr sends photographs from Metchosin from the last couple of nights.  It is often difficult to distinguish between Eupithecia ravocostaliata and E. nevadata.   The mid-costal dark patch is supposed to be rectangular in the former and triangular in the latter.  The difficulty is that this patch is often somewhat ill-defined in shape and it is difficult to say whether it is more nearly triangular or more nearly rectangular.  The patch looks unambiguously triangular in this one, so we feel fairly confident in labelling it Eupithecia nevadata.
