About Ancylis diminuatana Kearfott, 1905
Ancylis geminana, commonly known as the festooned roller, is a moth species belonging to the family Tortricidae. It was first described by Edward Donovan in 1806. This species can be found across most of Europe, and has also been recorded in North America. Its preferred habitats are fens, marshes, and damp heathland. The wingspan of adult moths ranges from 14 to 20 mm. The head is pale pinkish ochreous or white. Forewings vary in base color from red-brownish, to ochreous, to grey; they are more or less streaked with blackish on the posterior disc. The costa is strigulated, and broadly suffused with whitish on its anterior section. There are two or three elongated black subcostal dots towards the wing base. The dorsal area is suffused with whitish, bounded by a whitish line. This line forms a subtriangular projection in the middle of the area, a flat arch toward the posterior, and ends on the termen above the middle. The hindwings are light grey. Julius von Kennel has published a full formal description of this species. Adult moths are active in flight from May through August. The larvae feed on species in the genus Salix, including Salix aurita, Salix repens, and Salix cinerea. Larvae live inside leaf shelters they create by spinning multiple leaves together with silk.
