Ancylis subarcuana

(Douglas, 1847)

Wingspan c.15 mm.

A rather local species, though widely distributed, full details of its distribution are somewhat clouded by the fact it was formerly conspecific with A. geminana, and considered a form of that species.

Compared to the nominate form, it is rather more sombre in appearance with weaker or reduced markings and a paler, more greyish ground colour.

Frequenting dry pastures and sandy shorelines, the larva is associated with creeping willow (Salix repens), spinning a leaf into a pod and feeding within.

The adult moths fly between May and August, possibly in two generations.
