– Uncertain/Unknown – Insufficient Data 
– Day-flying
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: A.spinosella; A.semifusca
ID pointers: Typical form shows forewing greyish brown with a purplish reflection. Creamy white along the dorsum, interrupted by a darker brown oblique cross-band at one half and scattered whitish scales. There is also a shining unicolorous brown form aerariella.
Distribution: (Last record: 6 June 2019 at Jim Mart NR ) – Widespread and common to abundant among Rowan throughout the UK. Due to insufficient data status in the county is uncertain/unknown. Likely to be common where the food plant exists

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: Argyresthia conjugella
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 8 (August) to provide a full-year equivalent.

Population peaked around 2006, 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
