Knot Grass - Acronicta rumicis
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.
Found in various habitats.
On the wing in May to July, there is a second brood in southern England, appearing in August and September.
The larva is polyphagous on herbaceous plants such as Dock, Teasel, Mint and Plantain as well as deciduous trees and shrubs.
It is widely distributed and quite common in most of Britain, except Scotland where it is less frequent. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.
Fairly common in Leicestershire and Rutland. L&R Moth Group status = A (common and resident)
