   Jochen Möhr seems to have solved the problem of how to distinguish between Eupithecia nevadata  and E. ravocostaliata – by photographing one of each at his Metchosin home last night!  Look at the shape of the dark mid-costal patch – triangular in nevadata and a thin rectangle in ravocostaliata.   Klaus Bolte, in his monograph on Canadian pugs, also mentions that the shade of brown in the two species is different.  Difficult to describe in words, but quite evident in Jochen’s photographs.
