Eudonia mercurella

(Linnaeus, 1758)

---

Wingspan 16-19 mm.

A common species in most of Britain, though its similarity to several other species make it difficult to identify.

The adults, which are easily attracted to light, fly at night from June to September, but can be disturbed from their daytime resting places of tree trunks and rocks etc.

The larvae, like many of its congeners, feed on mosses growing on tree trunks and walls.
