– Generally Common / Widespread 
– Leaf-miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required. ID pointers: This species feeds on beech (Fagus sylvatica). The adults are rarely seen and this is another of the very similar Nepticulidae group.
Distribution: National Status – A widespread and fairly common species throughout the British Isles. Status in Derbyshire can only be assessed by the quantities of leaf mines recorded. It is likely to be a well spread and common species.
General Comment: Notes by Christian Heintzen on image dated 4/11/2025 – on Beech (Fagus sylvatica), > tightly undulating gallery mine moving between two lateral veins towards leaf margin > oviposition in or near axil between lateral vein and midrib > frass initially in narrow central line then becoming dispersed
Mine Period Additional: Leaf Mine – June and July & August – October
Mine ID Difficulty:
– Care required in ID process as confusion with similar leaf mines. Quality photos of the mine required. Mine Type/s: Gallery
Mine Feeding Method/s: N/A
Mine Comment: Best identified by the way the larva feed, creating an S-shaped mine, usually within the confines of two veins, leaving a diagnostic feeding pattern in the leaves. The egg is laid on the underside of the leaf against the mid-rib amongst hairs in the angle with the leaf vein. In the similar looking mine of Stigmella hemargyrella the egg is positioned away from mid-rib. During the autumn it is a good time to find the mines of Stigmella tityrella on the ground amongst fallen beech leaves, easily discovered as a so called “Green Island” on an otherwise brown beech leaf. The mines are nearly always vacated but some are still tenanted. Many of the larvae in the tenanted mines are parasitised and some still contain the larva of most probably a parasitic wasp, actively devouring its host.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
