University of Alberta E.H. Strickland Entomological Museum Read more about this collection »
SeasonalityAdults fly from June to beginning of October, reaching their peak flight in July. Specimens are generally attracted to light.
IdentificationHead and antennae silvery grey, labial palpi porrect, heavily scaled, silvery grey. Thorax and legs silvery grey. Forewings hooked, typical of the genus. Dorsal surface of forewings silvery grey with slight brownish pigmentation. A large golden area is present anteriorly, but does not reach the apex. Some specimens have darker forewings with two faint, thick oblique bands extending from the anterior to the posterior wing margin. Hindwings are grey to light brown, becoming somewhat translucent basally. Ventral wing surfaces, legs and abdomen silvery grey. This is a very distinctive species that cannot be easily confused with the other Alberta species.

Life History
Unknown. Pupation takes place in elongated silken cocoons. Adults of this species are among the earliest fliers, even before the snow has melted, having been captured as early as the end of April (pers. obs.).
Conservation
Not of concern. This native species can become locally abundant, but never in big enough numbers to cause any observable damage to host plant.
Diet Info
Chokecherry (Prunus virginiana).
