The Moths of Suffolk
2482 White-line Snout, Schrankia taenialis, (Hübner, 1809)

National Status : Notable Nb

Local Status : Locally extinct (SMP Status 4)

Habitats : Open moorland, conifer plantations, wet broadleaved woodland

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

Larval foodplants : Not known in the wild

Morley's Final Catalogue : Hitherto supposed very rare, noted only at Beccles and Stowmarket. But both (including Pinion-streaked 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 18-24mm
