Brown Silver-line Petrophora chlorosata

(Scopoli, 1763)

---

Wingspan 31-37 mm.

A fairly common moth over much of Britain, this species can often be disturbed in the daytime by walking through bracken.

It flies in a single generation during May and June, and occupies woodland and upland areas where its foodplant grows in profusion.

Bracken (Pteridium aquilinum) is the foodplant of the caterpillars, which occur from July to September.

The species flies at dusk and into the night, and is strongly attracted to light.
