The Moths of Suffolk
1787 Argent and Sable, Rheumaptera hastata, (Linnaeus, 1758)

National Status : Notable Nb

Local Status : Locally extinct (SMP Status 4)

Habitats : Open, partially cleared or coppiced broadleaved woodland, newly planted conifer plantations, moorland and bogs

Flight Period : Single-brooded; May to June

Larval foodplants : Seedlings of Downy and Silver Birch and also on Bog-myrtle

Morley's Final Catalogue : Essentially a sylvan species. Stowmarket and Bentley (Crewe and other earlier collectors); Belstead (Lingwood). This beautiful moth used to flit about the birch bushes in Bentley Woods, as numerously as it does in the New Forest, during at least the decade 1893-1904; then pheasants were introduced, and our eyes are gladdened with its presence no more. Un-recorded elsewhere; but seen during 1894 in Holbrook Park (Morley), where we sincerely hope it yet survives.

Wingspan details : Forewing 16-19mm, Wingspan 34-38mm
