Ancylis geminana

Ancylis geminana, the festooned roller, is a moth of the family Tortricidae. It was described by Edward Donovan in 1806. It is found in most of Europe and has also been recorded from North America. The habitat consists of fens, marshes and damp heathland. The wingspan is 14–20 mm. The head is pale pinkish ochreous or white. The forewings are red-brownish [or ochreous or grey], more or less streaked with blackish in disc posteriorly. The costa is strigulated and anteriorly broadly suffused with whitish. There two or three elongate black subcostal dots towards base. The dorsal area is suffused with whitish, limited by a whitish line forming a subtriangular projection in the middle and a flat arch posteriorly, ending on the termen above middle. The hindwings are light grey. Julius von Kennel provides a full description.

Adults are on wing from May to August.

The larvae feed on Salix species, including Salix aurita, Salix repens and Salix cinerea. They live between leaves spun together with silk.
