– Significant Record / Very Rare / Vagrant
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Acleris cristana
ID pointers: Perhaps the most varied of British tortrix moths. Can be confused with A.cristana which has a more concave forewing costa and two prominent scale tufts. The forewing costa is strongly curved from the base and coarsely fringed with scales. A scale tuft near mid-wing. Other scale tufts can be visible near the wing base and near the tornus, but these can disappear with wear. Usually three patterned types – 1) Uniform in colour and appearance 2) longitudinal markings typically stripes from wing base to apex 3) transverse markings, often as a crossband.
Distribution: (First record: 1975 ) – (Last record: 24 December 2024 at Long Clough ) – Very few Derbyshire records, so status is uncertain/ Rare. Records that do exist are widespread across the county.

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: Acleris hastiana
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 2010, reaching above average levels. The lowest population point occurred near 2024, 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
