Size
wingspan 29-36 mm, based on two Internet photos
Identification
Adult: forewing color and pattern variable but the image shown at
CBIF (presumably representing a typical specimen) is virtually identical to the photo by
John Davis
in typical specimens, forewing basal area, AM band, and PM band dark gray; medial area pale gray or whitish; basal band and subterminal area yellowish-orange; color in subterminal area extends along costa to apex, and extends to outer margin at anal angle; in some specimens, the yellowish-orange color may diffuse into the basal and medial areas - in other words, covering much of the wing (see example photo by Jim Vargo at
MPG)
hindwing whitish basally, shading to pale brown near outer margin
Range
British Columbia to Californina, east to Utah
Food
larvae have been recorded feeding on leaves of
Beaked Hazelnut (
Corylus cornuta)
See Also
very similar to some specimens of
Dysstroma sobria and
D. truncata, both of which may have yellowish-orange shading in basal and subterminal areas of forewing, as in
ochrofuscaria (compare images of all three species at
CBIF, and of
sobria and
ochrofuscaria at
MPG)
[note that the specimen correctly labeled
D. walkerata on
this MPG plate is mislabeled
D. ochrofuscaria on
this MPG plate]
