Semiothisa californiaria
described in 1871 by Packard, who originally placed it in genus Macaria
wingspan 22-29 mm, based on six Internet photos
Adult: forewing whitish to pale brown with sparse dark speckling; small black patches along costa represent upper ends of AM, median, and PM lines, which are otherwise missing or faint; broken dark patch about one-third distance from costa along PM line; some individual have slightly darker shading beyond PM line; hindwing color similar to forewing but with small discal spot as its only marking
Texas to California, north to Alberta and British Columbia
prairie badlands (in Alberta); adults are nocturnal and come to light
adults fly from March to October in California (2 broods); possibly all year in Texas
larvae feed on Big Deervetch (Lotus crassifolius) on the west coast, and presumably other legumes in the interior where Big Deervetch does not occur
Life Cycle
two generations per year in Alberta; perhaps more in the south
