Cloaked Minor Mesoligia furuncula
([Denis & Schiffermüller], 1775)
Wingspan 22-28 mm.
A very variable species with a wide range of colour forms and patterns. One form, bicoloria, has the forewing sharply demarcated between pale and rufous. Other forms often show less contrast.
It is commonest around sand-dunes, grassy seaside slopes and other coastal habitats, but occurs in inland areas, with a distribution throughout the British Isles.
The moths fly between August and September, and the larvae feed on grasses.
