– Generally Common / Widespread
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Apple Ermine (Yponomeuta malinellus), Spindle Ermine (Yponomeuta cagnagella) and Willow Ermine (Yponomeuta rorrella)
ID pointers: Difficult to ID, so best guide is the food plant. Two-toned grey-whitish forewing with a scattering of small black dots.
Distribution: Widespread and common wherever there is Hawthorn, Blackthorn & Cherry

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: Yponomeuta padella
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 6 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.
ⓘ
Purple line rises = years better than average; falls = years worse than average.

Population peaked around 2006, 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
