Morley’s Final Catalogue: Not listed. The Nepticulids were not extensively studied and only 21 are listed.

Recent Status: The species is well recorded in lighter land areas of Suffolk.

Life Style: The moth is double brooded flying in April, May, June, August and September and comes to light. The larvae mine leaves of Quercus and Castanea.

Identification: The moth is a dark bronze fuscous with a purple sheen particularly at the tip. The head tuft is black and the scape and collar are white. Genitalia dissection is required for identification. More Info
The larva creates a gallery from an ovum on the underside of a leaf. The mine is broad with a central line of dispersed frass. It is very similar to the mine of S. svenssoni, but that species rarely uses Castanea.

Verification Grade Comment: If on sweet chestnut otherwise needs breeding out and dissecting
