– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Anacampsis blattariella
ID pointers: Two forms one fairly unmarked pale yellowish-greyish and a darker form. The darker form is grey with an obvious black area in the dorsal half of the forewing forming a large mark when the moth is at rest (Browner in the paler form). A white band across the wing (creamy in the paler form). Variably speckled in both forms.
Distribution: (First record: 1916 ) – (Last record: 21 August 2015 at Melbourne ) – Presumably a localised species in the county where there is Poplar & Aspen. Very few records, and since 1986 only three this is one which was verified by the CMR at the time and one from Toyota, Derby 28/7/2004 and one from Chesterfield 25/8/2007

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: Anacampsis populella
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 23 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 2007, reaching above average levels. The lowest population point occurred near 2004, 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
