General Description
provided by University of Alberta Museums
A medium-size (3.6-4.2 cm wingspan) grey-black moth with a silvery sheen in fresh specimens. Forewings are mottled pale grey in the basal and subterminal areas, with dark blackish-brown in the lower median area and along the subterminal line. The antemedian and postmedian lines and the area below the stigma are dark red-brown. Stigma is silvery white, forming an outward curving arc with a rounded tip and with a widely separated fork at the upper end. About one-third of the way down the subterminal line is a black dash which connects the subterminal and postmedian lines. This black dash is diagnostic and will separate californica from the very similar A. pseudogamma. Hindwings are dark sooty brown-black, paler in the basal half and shading into a wide dark terminal band. The antennae are simple and both the sexes are alike.

Life Cycle
provided by University of Alberta Museums
Adults are both noctural and diurnal, and have been collected in light traps as well as while nectaring during the day. In late fall, they can be quite common and found nectaring during the afternoon at late blooming plants such as Alfalfa and garden Marigolds. It appears that there is a small spring emergence and a much larger late summer and fall generation in Alberta.

Trophic Strategy
provided by University of Alberta Museums
No Alberta data. A pest on a variety of forage and vegetable crops further south, and probably also a variety of native herbaceous plants. Eichelin and Cunningham (1978) list over 50 genera in over 25 families of herbaceous plants and woody shrubs used as hosts by larvae of californica.

Autographa californica
provided by wikipedia EN
Autographa californica, the alfalfa looper, is a moth of the family Noctuidae. The species was first described by Adolph Speyer in 1875. It is found in western North America from southern British Columbia to Baja California and to Manitoba, South Dakota, Colorado and New Mexico.
The wingspan is 36–42 mm. The moth flies from July to October depending on the location.
The larvae feed on a wide range of plants. Recorded food plants include species of families Apiaceae, Aquifoliaceae, Asteraceae, Boraginaceae, Brassicaceae, Caprifoliaceae, Chenopodiaceae, Cucurbitaceae, Ericaceae, Eschscholzia, Fabaceae, Grossulariaceae, Liliaceae, Lamiaceae, Linaceae, Malvaceae, Plantaginaceae, Poaceae, Podocarpaceae, Polygonaceae, Rhamnaceae, Rosaceae, Rutaceae, Scrophulariaceae, Solanaceae and Verbenaceae.

Autographe de la luzerne
Autographa californica, communément appelé l’Autographe de la luzerne[1], est une espèce nord-américaine de lépidoptères de la famille des Noctuidae.
Description
L'imago a une envergure de 36 à 42 mm. Les ailes arborent des motifs de différents tons de gris sur les ailes. Les ailes antérieures portent en leur centre une marque argentée en forme d'arc dont l'extrémité arrondie pointe vers l'arrière quand les ailes sont fermées. Les ailes postérieures sont brun-noir, avec une large bande terminale noire. Les antennes fines sont semblables chez les deux sexes.
La chenille est vert pâle avec de fines bandes dorsales longitudinales blanches. Elle porte deux paires de fausses pattes.
Répartition
Autographa californica est répandu dans l'Ouest de l'Amérique du Nord. On le retrouve de l'Alaska au Nord du Mexique, à l'est jusqu'au Manitoba.
Biologie
La chenille se nourrit d'une grande variété de plantes. Les plantes hôtes sont réparties dans les familles suivantes : Apiaceae, Aquifoliaceae, Asteraceae, Boraginaceae, Brassicaceae, Caprifoliaceae, Chenopodiaceae, Cucurbitaceae, Ericaceae, Fabaceae, Grossulariaceae, Liliaceae, Lamiaceae, Linaceae, Malvaceae, Plantaginaceae, Poaceae, Podocarpaceae, Polygonaceae, Rhamnaceae, Rosaceae, Rutaceae, Scrophulariaceae, Solanaceae, Verbenaceae[2].
Parmi les plantes hôtes se retrouvent des espèces cultivées, ce qui fait de l'Autographe de la luzerne un ravageur de cultures. Un insecticide a été mis au point pour lutter contre Autographa californica et d'autres espèces apparentées[3].
