Discestra mutata
described in 1913 by Dod, who originally placed it in genus Mamestra
Explanation of Names
mutata: from the Latin verb "mutare" (to change; to mutate); I don't know how the word applies to the moth but it's the origin of the suggested common name The Mutant, intended as a companion to the name of its sister species The Nutmeg
wingspan about 34-35 mm, based on two Internet photos
Adult: forewing brownish-gray with double AM and PM lines; orbicular spot oblong; dark shading in lower half of reniform spot; claviform spot cone-shaped (may be dark in some specimens, pale in others); subterminal line whitish, distinct, with large W-shaped jog near middle; fringe checkered with pale and dark scales; hindwing dirty white basally, shading to dark gray distally, with dark gray veins; fringe whitish
western North America: Texas to California, north to British Columbia, east to Manitoba
adults fly from April to October in California
See Also
The Nutmeg (Discestra trifolii) forewing has a more circular orbicular spot (not oblong), a less distinct subterminal line, and the ground color is yellowish-gray (not brownish-gray) -- compare images of both species at CBIF
Discestra obesula forewing is darker overall, with contrasting pale shading in subterminal area, and doesn't occur south of Oregon or west of Alberta -- compare images of both species at CBIF
