Drab Looper Minoa murinata
Wingspan 14-18 mm.
As the English name suggests, this is a dull, unpatterned species, but is one of the few day-flying moths, preferring sunny weather.
When fresh, the wings have a delicate silky sheen, but this soon fades.
The species occurs in the southern parts of England and Wales, occupying wooded habitats.
The larval foodplant is wood spurge (Euphorbia amygdaloides), and the flight period is May to June, with a partial second brood in August in the south.
