Syngrapha? - Syngrapha borea

Syngrapha? - Syngrapha borea
Sitka County, Alaska, USA
August 5, 2013
I'm pretty sure this is a Syngrapha, but I'm not sure what species.

not S. orophila?
In reading the descriptions and differences between borea and orophila on PNW Moths, borea should have a yellow spot at the anal angle of the forewing which should also be 13-16 mm. If these are your usual 1/4 inch squares, the forewing of this moth is closer to 30 mm which is the size of a large orophila. S. borea does have a brown tuft on the thorax as does this individual.

These seem like good questions to me. The squares are 5mm/.25 inches. As best I can measure (if I understand what I should be measuring), the forewing is about 16mm. I guess that's on the large end for S. borea and the small end for S. orophila. It does seem to be missing the yellow spot at the anal angle, though this moth was fairly worn (especially compared to the examples on PNW Moths), so maybe that's part of it? Neither species seems to be common/expected in the region if the lack of collections/reports is any indication.

I may have made a collection of this one, and if so, perhaps there is some hope that it could be verified.

Moved
Moved from Syngrapha.

Moved
Moved from Moths. Seems to be no page for S. borea to move this one to.

8934 - Syngrapha borea
ID confirmed by Jim Troubridge to whom I sent the photograph. (no rsvp, thanks)

Compare to Autographia:
Autographa ampla - Raspberry Looper 8923

 
Thanks -
Do the yellow-underwings eliminate Autographa? The photos I found for A. ampla don't show yellow on the hind wings.
