The Moths of Suffolk
1656 Satin Lutestring, Tetheella fluctuosa, (Hübner, 1803)

National Status : Local

Local Status : Unknown (SMP Status 3)

Distribution and abundance : Only one record in recent years.

Habitats : Mature broad-leaved woodland and heathland are the quoted habitats

Flight Period : Single-brooded; literature states June to early August

Larval foodplants : Various species of birch

Records : Hollesley (RGT StLeger, 1993)

Morley's Final Catalogue : 'Stowmarket' (Stainton's Manual 1857, 175); 'my specimens have come from Huddersfield and Ipswich' (Newman's Moths 1871, 240). "Recorded in Stainton's Manual as occurring at Stowmarket, and by Newman as having been received from Ipswich these latter were probably not Suffolk specimens" (Bloomfield 1890, 55) in which case they lose all point in having the locality thus quoted by Newman; and, further, if they were not, we still have the 1857 record to rely upon. Pretty surely extinct with us now, thanks to early dealers' greed.

Wingspan details : Forewing 17-21mm, Wingspan 35-38mm
