Identification
Distinguished from similar noctuid by its small size (16–17 mm wingspan), western North American distribution, and specific larval plant associations with Malacothrix glabrata and Rafinesquia neomexicana. The 'Red-lined Moth' suggests diagnostic wing patterning, though detailed comparison characters with congeneric are not available.
