Acleris aspersana

(Hübner, [1817])


Wingspan 13-16 mm.

Quite a small member of the Acleris genus, this species prefers open areas such as grassland, downs and heaths.

The adults fly from afternoon onwards, in July and August, and the species is fairly common locally throughout the British Isles.

In common with many of its congeners, the larvae feed in rolled-up leaves of a range of herbaceous plants.
