National Status : Local

Local Status : Resident (SMP Status 3)

Distribution and abundance : Local, not infrequent in northern river valleys and coastal areas

Habitats : Wet woodland, fens, wet meadows, riversides and other marshy areas

Flight Period : Single-brooded; June to mid-August. Occasional partial second brood late August to late September

Larval foodplants : Not known in the wild

Morley's Final Catalogue : Hitherto supposed very rare, noted only at Beccles and Stowmarket. But both (referring to this species and White-line Snout) - that the species be distinct is most improbable - flew to light and sugar at Fritton marshes and those of the Waveney at North Cove in the utmost profusion in September 1932-4 (D, Mr); and the former, which occurs at Barton Mills (Waters), was taken at Blythburgh and Benacre Broad in 1933-6 (Mly).

Wingspan details : Forewing 9-11mm, Wingspan 16-22mm
