Shore Wainscot Mythimna litoralis
Wingspan 36-42 mm.
A strictly coastal species, occurring locally in sand dunes around the English and Welsh coastlines, more rarely in Scotland and Ireland.
A quite distinctive moth, with its blackish-bordered white streak along the length of the forewing.
The larvae feed on marram (Ammophila arenaria) during the night, burrowing in the sand to hide by day.
