Morley's Final Catalogue: Semiothisa brunneata, Thb., is exclusively northern in Britain.

Recent Suffolk Status: Scarce immigrant, arriving more regularly in recent years. First county records were in 1946 (2). Not recorded again until 2009 when there was a national influx from the low countries, with 13 records of 19 moths at light. There were smaller influxes in 2010 and in 2011. Then followed a number of years with no records, until 2020 and 2021 when there were single records in each of them. In both 2022 and 2023 there were quite big influxes again, widely across the county and not only along the coast.

Life history: Single-brooded. Moths are day-flying and also come to light.

Identification: Dingy shell is much smaller and duller in colour.

Habitat: As a migrant has turned up in all habitats including gardens.
