Lyme Grass Longalatedes elymi

Wingspan c.36 mm

The Lyme Grass is a local and scarce species, mainly restricted to coastal sandhill habitats on the East Coast, from Kent northwards into eastern Scotland, as well as a few coastal localities in north-west England.

The adult moths are on the wing from June until August, and are readily attracted to light.

The moth's vernacular name derives from the foodplant, lyme-grass (Elymus arenarius), in which the larvae feed inside the stems, usually below the surface of the sand.
