– Leaf Miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required. ID pointers: A Leaf-miner – The gallery is filled with a greenish-brown frass. A clear corridor with the egg on the underside of the leaf near a vein. The mine is a long sinuous gallery crossing and turning back on itself. The mine in the photograph is on Rosa (Rose) Adults not often seen but plain bronzy wings, tinged greenish on the inner two-thirds, and slightly reddish towards the tip.
Distribution: (Last record: 14 August 2025 at Glossop ) – National Status – Common – Derbyshire status unknown, likely to be a common leaf-mine. Adults are rarely recorded. Leaf Mines survey 20/8/2025 at Wyver Lane

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.
Land-cover * shows the variety of land-cover within the VC57 area, based on the CORINE (Coordination of Information on the Environment) forty-four thematic classes of land-cover. This will show, to a greater or lesser degree, the number and variety of moths found in different land-cover types. The UK continues to operate within the Copernicus programme, with the UK Centre for Ecology & Hydrology (UKCEH) providing Corine Land Cover (CLC) datasets for the UK and its territories.

CUSUM Analysis: Stigmella anomalella
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 7 (July) 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
