Autographa pseudogamma (Grote(1), 1875)

Plusia pseudogamma Grote, 1875

Phytometra pseudogamma ab. freya Strand, 1917

Phylogenetic sequence # 931196 (2)

Lafontaine & Schmidt (2010) listed 18 species of the genus Autographa in America north of Mexico. (2)

Powell & Opler (2009) listed the forewing length 17-18 mm. (3)

In the north and east it ranges from Nova Scotia to British Columbia, north to Alaska; south to Maine, Michigan, South Dakota, Montana, Wyoming (Eichlin & Cunningham, 1978). In the west it ranges into the central Sierra Nevada mountains, northeastern Nevada, Arizona and New Mexico (Powell & Opler, 2009).

Larvae are generalist feeders on herbaceous plants. Adults have been observed nectaring at fireweed blossoms (E.H. Strickland Museum).

Similar to A. californica but can be separated from pseudogamma by the short, fine black dash connecting the subterminal and postmedian lines near the apex of the forewings (E.H. Strickland Museum).
