– Significant Record / Very Rare / Vagrant
– care required in the identification process, as confusion with similar species is likely – quality photographs required. ID pointers: The wings are grey brown and rounded at the tip. Very plainly marked but there is often a row of small black dots along the inner edge of the fringed outer wing. Male has feathered antennae.
Distribution: (Last record: 2021 ) – A resident that has become exceedingly rare and locally distributed in Derbyshire. Was a common species, especially in the south but now restricted to woodland containing Aspen (Populus tremula). Since 2007 there has been one record in 2019, and one record in 2021.

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: Orthosia populeti
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 2011, reaching above average levels. The lowest population point occurred near 2006, 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
