About Amphipoea fucosa Freyer, 1830
This moth species has a wingspan of 29 to 35 millimeters. It resembles the closely related ear moth (Amphipoea oculea), but is larger in size. Amphipoea fucosa is univoltine, meaning it produces only one generation per year, with adults on the wing in August and September. At night, adult moths can be found visiting flowering ragwort (Jacobaea vulgaris), marram grass, and rushes, and they will also come to light traps. This species overwinters in the egg stage. Larvae hatch and can be found from May to June, feeding inside the stems and roots of a variety of grasses. In the wild, larvae have been recorded feeding on common saltmarsh grass (Puccinellia maritima); in captivity, they will accept cock's-foot (Dactylis glomerata) and annual meadow grass (Poa annua). Pupation occurs in the soil next to a host plant root, and takes approximately one month to complete.
