Could be verberata
but I don't know how to distinguish verberata from bicolorago except perhaps by the extent and density of gray shading on the hindwing, which isn't visible enough in this photo.

The 4 photos of bicolorago by Jim Vargo at MPG show considerable variation, and a couple of them look very similar to his single specimen of verberata. Both species occur in British Columbia (see Canadian distribution listed under Sunira), only verberata is listed from Oregon on the ORST page, and only bicolorago is listed from California (a single specimen in 2002).

All the BugGuide photos currently on the bicolorago page are from the eastern states and Ontario. I think they're assumed to be that species because verberata hasn't yet been collected from those areas.

 
Comment on A. verberata
Robin thank you for the comments and links. I had looked at all of them when the genus was verified and after Lars Crabo gave the species ID. Oregon State lists 8 bicolorago, 79 decipiens, and 6 verberata in the collection which is something to ponder also. I passed on to Lars your comments and his return was essentially a verification of where we are. His words:

"Someone needs to look at this. The whole world of noctuids is full of
little problems like this. Bicolorago is a very common eastern species.
The ultimate question will likely be whether verberata or decipiens is a
subspecies of bicolorago, unless someone dissects them and finds diagnostic
genitalia differences or there are significant DNA differences."

"The other problem is decipiens. Forbes, who wrote the Lepidoptera of New
York and neighboring states, calls the western species acta. A friend of
mine once told me that Forbes usually got it right, however, everyone else
seems to think that decipiens is the correct name."

"Having said all that, I had heard that at least one other person thinks that
one of our two western species is the same as bicolorago. I can't remember
which one it was!! How's that for brilliant?"

I feel there are some characters which might define this one specimen as verberata and not bicolorago but think we need to wait until others are captured. I failed to show the hind wing but will not next time. There seems to be a lot of variation in the species of this genus plus we have the disjunct nature of the geographic distribution. I really suspect verberata and dicolorago are the same species or one a sub species of the other. However, as Lars states, this is for the experts which is certainly not me.

 
A spread specimen
or a live individual showing the complete hindwing would be good; otherwise, maybe we'll have to wait for someone to do a revision of the genus...
