(Zincken, 1817)Wingspan c.20 mm.
One of the earliest Crambids to be seen during the year, with the adults flying from May through to August. The whitish streaks on this moth are narrower than other similar species, and the males are darker than the females.
Like several similar species, the moth is to be found in grassy areas, where the larvae feed on various types of grass stem.
It is common throughout Britain in suitable habitat, and flies naturally at night, though it is easily disturbed in the daytime.
