Above seems to lack the 'checkered' appearance that the iNat examples show but otherwise a good match. Appearance MAY be photo technique/gear? Possibly E. fabricata going by BOLD (Hobern). BOLD (Hobern) specimens of E. postvittana like this seem to be (south western) WA specimens. E. dotonata may be the best match for these subtle markings.
