Dot Moth Melanchra persicariae
Wingspan 37-40 mm.
Although very common and widespread in England and Wales, this species is almost unknown in Scotland, except the very south, where it occurs scarcely. It is local in Ireland.
Frequenting a range of suburban habitats, including gardens, waste ground and roadside verges, the adults are on the wing in July and August, and frequently visit the garden moth-trap.
The larvae feed on a wide range of garden and wild plants.
