Straw Dot Rivula sericealis
Wingspan 18-22 mm.
Relatively common in the southern half of Britain, and becoming gradually scarcer further north, this moth is also a suspected immigrant.
The two generations a year fly in June and July, and again in August and September.
Damp meadows and woodland are its favourite haunts, and it flies from dusk into the night when it is attracted to light.
Various grasses form the larval foodplants.
