– 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: In the adult the head is black in the male, between orange and black in the female. The forewing has a greenish golden metallic lustre with silver fascia.
Distribution: National Status – Widespread and common throughout the British Isles. A lack of records and data make the Derbyshire status unknown. Likely to be common where there is Hawthorn. 124 mines discovered on 20/8/2025 on Hawthorn at Wyver Lane, Belper.
General Comment: None Mine Period Additional: May & June and late July – September – Overwinters as a pupae outside the mine
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 larvae mine the leaves of Hawthorn. The mine starts as a slender, winding corridor with a central line of frass, which then abruptly widens into a blotch with irregular frass, usually located along the leaf margin.

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 hybnerella
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 16 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 10 (October) to provide a full-year equivalent.

Population peaked around 2025, reaching above average levels. The lowest population point occurred near 2022, 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
