– Uncertain/Unknown – Insufficient Data
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Scoparia ambigualis
ID pointers: Forewing white, unevenly speckled blackish, resulting in a mottled appearance. Two whitish cross-lines, one before one third and the other just beyond two thirds. There is an obscure line near the termen that meets this second cross-line near the middle resulting in a broad X shape. Forewings appear more pointed than S.ambigualis.
Distribution: Uncertain – scattered records from the western-central to North Western side of the county, particularly from the dales.

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: Eudonia truncicolella
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 13 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 2013, reaching above average levels. The lowest population point occurred near 2012, 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
