Scientific name: Idaea aversata

Mid-June to mid-August with a partial second generation September to October north to Yorkshire. Common throughout Britain with two distinct forms.

The fawn or sandy-brown coloured wings are peppered with black and held out flat at rest. The typical ribboned form has a dark cross-band running across all four wings whereas the plain form f. remutata only has narrow cross-lines. Both forms are equally frequent in the south whereas the plain form is more numerous in the north.

They overwinter as small larva and pupate in plant debris near the ground. The adults often come to light in large numbers.
