Slender Brindle Apamea scolopacina
Wingspan 32-36 mm.
A rather attractive species which does not tend to vary as much as its congeners.
Frequenting woodland habitats, it flies in July and August, and is locally distributed in the southern half of Britain, but absent further north.
The larval foodplants are a range of woodland grasses, including wood millet (Milium effusum) and wood-rushes (Luzula spp.).
