Common NameDelicate Silver Y SeasonalityAdults have been collected in Alberta in July and the first half of August. IdentificationA medium-size moth (4.0-4.5 cm wingspan). Forewings are dark shining grey with strong violet tones. The median area of the forewings below the stigma is a darker rusty black, often with a small rust patch along the lower postmedian line. The prominent stigma is an outward curving silver arc, with the upper half forked. Hindwings are smoky brown, darkening into a broad band along the outer margin. The similar A. california is a bit lighter and less purple, and can be separated from pseudogamma by the short, fine black dash connecting the subterminal and postmedian lines near the apex of the forewings.
