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

Recent Status: This scarce species in the UK was first recorded in Suffolk as the larval mine during 2020.

Life Style: A double brooded species flying in mid-summer and early autumn. The larvae mine leaves of Filipendula vulgaris and Filipendula ulmaria. They pupate on the ground. The pupal stage passes the winter.

Identification: The moth is a small Stigmella species with brown, sometimes purple tinged forewings and a white fascia. The head is dull brown and the scape paler. The moth can be identified by breeding out from a mine or by genitalia dissection. http://www2.nrm.se/en/svenska_fjarilar/s/stigmella_genitalia.html
The egg is laid on the top side of a leaf usually near a vein. The bright amber yellow larvae create a mildly contorted gallery with a central broken frass line. The gallery and frass line gradually widen.

Determination by Genitalia Examination Required

Mine: Either the leaf or a good photograph required
