June to October. Common and resident to Britain with large numbers of migrants also often seen on the south coast.

The forewings are long, narrow and rounded. They are variable in colour from reddish brown to blackish brown but with a small black dot close to the leading edge at the tip. The yellow hindwings have a narrow black band without the dark crescent or clouding found in other yellow underwings.

The adults come to light in large numbers and may be disturbed from plant debris or ground vegetation during the day. The larvae can be found from August to early spring, feeding at night and hiding underground during the day.
