Stigmella samiatella

(Zeller, 1839)88 / 4.062

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 (sometimes brown) 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
