Morley's Final Catalogue: North Cove marshes of the Waveney, at light on 13 September 1932 (Mly); Dunwich and Walberswick (Btn), Covehithe in 1936 (Gd). Doubtless much confused with the next kind.

Recent Suffolk Status: Local, mainly along the coast, the edge of the Brecks and river valleys in the county.

Life history: Single-brooded.

Identification: Most similar to White-mantled wainscot. Brown-veined wainscot has a clear black spot in the centre of the underside of the hindwing, has a more stocky body and lacks the collar of white scales above the thorax that White-mantled has (although this feature wears off rapidly). Twin-spotted wainscot is a much stockier moth, has plainer wings and an obvious white spot on the forewing. Other wainscots are bigger in size. Melanic forms of Brown-veined wainscot have been found in the county which can be more similar to Brown-veined but they are smaller than that species.

Habitat: Reedbeds, fens, marshes.
