Yorkshire Status: Common and widespread resident.

In 1883 Porritt wrote that Ingrailed Clay was "abundant in most places and no doubt common everywhere". It remains common and widespread over most of the county and numbers seem to be stable. Counts are commonly into double figures, the maximum being 101 at Spurn on 5/7/1982. It flies from May to August in a single brood, but in recent years we have had scattered records as late as November. This is an extremely variable moth with many different forewing markings, so it takes a little getting to know.

Sutton & Beaumont, 1989: Frequent or common in all five vice-counties. This species is very variable including a small moorland form which is common in suitable areas.
