Distribution and habitat

This species is present in most of Europe, in the East Palearctic ecozone and in the Near East.[2] These moths inhabit marginal areas of forests where host plants grow.[3]

Description

Ancylis obtusana has a wingspan of about 12 millimetres (0.47 in). Forewings are red brown, with a rounded reddish patch and costa stringulated (finely streaked) with white and brown. The hind wings are brownish. Similar species are Ancylis comptana and Ancylis mitterbacheriana.[3][4]

Biology

The adult moths fly from May to July. Larvae feed on alder buckthorn (Frangula alnus) and buckthorn (Rhamnus cathartica). They overwinter in leaves of these host plants that they spin together.
