– easy to identify, generally distinctive and unlikely to be confused with other species.ID pointers: Quite a chunky looking moth with rather broad and rounded grey wings, quite variable in colour and markings. An obvious small oval pale centred with a dark outline and a most conspicuous black lined kidney mark and outer cross-line that is pale bordered on the inner edge. Sometimes there is a black streak flicking through the central area of the outer cross-line. A superb image below shows an example of the dark colour morph f.suffusa.
Distribution: (Last record: 23 July 2025 at Torside, Glossop ) – A resident that is confined to the upland grit-stone moors of the Central and Peak areas of Derbyshire. All records apart from one recorded in a Darley Dale garden (2009) and another from a garden in Ripley (2008), have been recorded from moorland habitat.

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: Acronicta menyanthidis
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 15 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.
ⓘ
Purple line rises = years better than average; falls = years worse than average.

Decline periods
Population peaked around 2025, reaching above average levels. The lowest population point occurred near 2014, 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
