About Depressaria alienella Busck, 1904
Depressaria alienella is a species of moth belonging to the family Depressariidae. It was first described by August Busck in 1904. This moth is native to North America, where its recorded range extends from Yukon to Nova Scotia, and southward to New England, Arizona, and California. The wingspan of adult Depressaria alienella measures 18–21 mm. Its forewings are light fuscous, overlaid with red or reddish fuscous; they are irrorated with cinereous and fuscous scales, and marked with streaks of blackish fuscous. A small white discal spot sits at the end of the forewing cell, with fuscous markings positioned both before and after this spot. An indistinct row of small fuscous spots runs along the edge of the forewing termen. Adult moths are active on the wing between July and September. The larvae of this species feed on the flowers of plants in the Artemisia and Achillea genera.
