– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: < Phyllonorycter lantanella Phyllonorycter leucographella >
ID pointers: The adult moth is characteristically marked and cannot be confused. The silvery mine with brown speckling is located over the midrib or vein on the upper-side of the leaf, which is unusual. It also has a “double” mine within a mine, the outer mine being translucent and flecked with brown. Shown on Crataegus (Hawthorn). Also found on Prunus (Cherry) and Malus (Apple)
Distribution: (Last record: 22 November 2023 at Poppy Wood ) – Nationally thinly but widely scattered. possibly declining in northern areas – Derbyshire unknown – suspect well-spread throughout the county, but thinly distributed. Leaf mines recorded
General Comment: None Mine Period Additional: July, September and October. Possible confusion with P. leucographella
Mine ID Difficulty: Not Recorded
Mine Type/s: Not Recorded
Mine Feeding Method/s: Not Recorded
Mine Comment: None.

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: Phyllonorycter corylifoliella
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 17 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
