– 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), creating an S-shaped mine, usually within the confines of two veins. The adults are rarely seen and this is another of the very similar Nepticulidae group. Best identified by the way the larva feed, 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 angle with vein. S.hemargyrella has egg away from mid-rib
Distribution: (Last record: 25 November 2024 at Gnat Hole ) – National Status – A widespread and fairly common species throughout the British Isles. Status in Derbyshire not known as insufficent records but likely to be well spread.

If the Map Layers function fails, just refresh the page and it should be OK after. Use the +- zoom on the top left, or on a tablet, use two fingers to zoom. Remember, the last layer you ticked is the one which displays the popup information - they sit on top of each other - de-select then re-select, to see the popup values.
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 tityrella
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 11 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 2020, 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
