The Moths of Suffolk
1658 Oak Lutestring, Cymatophorima diluta, (Denis & Schiffermüller, 1775)

National Status : Local

Local Status : Resident (SMP Status 3)

Distribution and abundance : Known from only one site in the county, although relatively frequent there

Habitats : Mature woodland containing oaks

Flight Period : Single-brooded; late August to September

Larval foodplants : Oak (Pedunculate and Sessile)

Records : Thornham (various recorders, 1997 - 2003)

Comments : Work has been carried out to look for this species in suitable habitat elsewhere in the county, although to date this has failed to find the species. It is quite possible that this species could be discovered in other woods in the county in the future.

Morley's Final Catalogue : Very local, but by no means rare in only a few of our larger woods among oak and birch. Stowmarket (B); Needham (L); and Bentley (Ml), where it is always quite abundant on sugar in early September (Mly, Baylis, Platten, Hkg, Elliott, &c). At light at Henham (Mr, Gd), in Benacre Wood in September 1935-6 (Btn), and at Sotterly in Sept. 1937 (Gd).

Wingspan details : Forewing 15-17mm, Wingspan 33-36mm
