Moved from Eusarca.

Please compare:

Moved from ID Request. Bob Patterson email comments: I see no real difference between 6930 and 6931 in Walsh's photos, certainly nothing to aid in deciding Brummermann's strongly marked specimen.
It is of course possible that 6931 at MPG has been misidentified in the collection at Bohart Museum with the error copied and posted at MPG. I do not know if there is any difference in wing shape between the sexes. All I can say is that the 6931 specimens at MPG fall within the range of Eusarca wing shapes.
What is needed is a look at a drawer full of specimens (if a decent collection exists) and, perhaps, at genitalia

possibly 6930 – Eusarca galbanaria (Walsh photo) or 6931– Eusarca detractaria (Walsh photo). Note that Bruce's photo of 6931 is NOT the same moth as shown on MPG. Going to require some help on this one.

I sent the link ...
to Bob Patterson at MPG. Hope he has an opinion.

It looks most like
Walsh's detractaria, but you are right something is wrong between Bruce and MPG. I hope an editor of MPG sees this
