Here are two lepidopterans I collected in Oregon (USA). The wingspan of the bigger one (on the left) is ~4 cm. I spent a lot of time browsing this website hoping to find a match, but I didn't have success.

$\begingroup$ Out of interest, did you find these in the same place at the same time? They have fairly different phenologies... $\endgroup$– theforestecologist ♦Jan 22, 2016 at 6:23

$\begingroup$ @theforestecologist approximately at the same place and time. Time period 1 month, place - the same region of a town. $\endgroup$– Salvador DaliJan 22, 2016 at 7:53

The one on the left is a Lunate Zale Moth (Zale lunata). See Western Washington University's PNW moths page for more detailed info.
The one on the right is a Forage Looper Moth (Caenurgina erechtea). See here for an image similar to the one in the question. And again take a look at Western Washington University's PNW moths page for more detailed info.
