Knot Grass Acronicta rumicis

(Linnaeus, 1758)

Wingspan 30-35 mm.

A variable species, some examples of which can resemble other Acronicta species, but this moth usually shows a curved white mark near the rear edge of the forewing, even in melanic specimens.

It is widely distributed and quite common in most of Britain, including Scotland where it occurs widely but is less frequent.

On the wing in May to July, there is a second brood in southern England, appearing in August and September. The larvae feed on a range of herbaceous plants.
