– Leaf Miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required. ID pointers: Adult is like most other stigmella being plain dark bronzy brown fore-wings, a white collar and eye-caps.
Distribution: (Last record: 6 October 2025 at Sunnydale LNR, Derby ) – National Status. Locally through England and Wales. Derbyshire status unknown insufficient records but likely to be well spread in appropriate habitat.
General Comment: None Mine Period Additional: Leaf Mine July and August to October. Larvae are active in July and then from September to October. It overwinters as a pupa in a pale cocoon on the ground.
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: Not Recorded
Mine Comment: The egg is found on the underside of the leaf. The larvae create a highly contorted, gradually widening corridor mine in the leaves of Tilia species (lime trees). The mine is often initially only on the underside of the leaf, and the frass (excrement) is deposited variably, sometimes in a narrow central line or widely dispersed. The larvae is yellow with a pale brown head. The gut line is green.

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.

CUSUM Analysis: Stigmella tiliae
About this chart: CUSUM (Cumulative Sum) charts track long-term trends in moth populations [ filtered by 'Adult' and 'Mine' life stages ] by showing whether each year’s counts are above or below the historical average. Even small shifts build up over time, making trends of growth, stability, or decline easier to see. CUSUM highlights trend-consistency — asking: “Across the years, have moth counts mostly stayed above or below average?”
The data sample has 21 gap year/s here (zero records) between 2000 and 2025. The moth may have been present in those gap years, but no data was available. Too many year-gaps may exaggerate or skew the chart.
Counts for the current year (2025) are pro-rated based on data available up to month 9 (September) to provide a full-year equivalent.

Population peaked around 2025, reaching above average levels. The lowest population point occurred near 2023, showing a significant decline.
What the Y-axis "Cumulative Deviation" means: Cumulative Deviation shows the running total of how each year’s moth population count differs from the long-term average. i
