Brown –  Significant Record / Very Rare / Vagrant    
Taxonomy:   Macro   >>  Geometridae  >> Larentiinae
ID Difficulty:  Red – difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.
Confusion Species: Fletcher’s Pug
ID pointers: A large usually pale grey pug, with faint tram-lines/cross-lines and a small, elongated black central spot running indirectly towards the leading wing edge.
Distribution:  (First record: 27 May 2002 )  –  (Last record: 2 June 2024 at Cromford )  –  First recorded in Derbyshire 27.5.2002 at Matlock, then several recorded from High Tor, Matlock in June 2004 and again in May 2011. One recorded from a garden in Darley Dale in 2012. One trapped at Cromford on 1st October 2023 by Clive Ashton, which was way out of  the known flight period? The larva feed on Lime, in particular Small-leaved Lime, which exists on the cliffs above Matlock Bath. So it is possible that small localised colonies exist in the Matlock, Darley Dale area, close by the food plant. A further individual was recorded from Cromford on 2nd June 2024. Another from Cromford May 2025 – Certainly there is a small relict population existing in Cromford

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.

******* Choose ONLY one at a time, of either Monad, Tetrad or Hectad Distribution - each has it's own set of data. Also, the distribution maps cover ALL recorded data. *******

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.

Land-cover * shows the variety of land-cover within the VC57 area, based on the CORINE (Coordination of Information on the Environment) forty-four thematic classes of land-cover. This will show, to a greater or lesser degree, the number and variety of moths found in different land-cover types. The UK continues to operate within the Copernicus programme, with the UK Centre for Ecology & Hydrology (UKCEH) providing Corine Land Cover (CLC) datasets for the UK and its territories.

CUSUM Analysis: Eupithecia egenaria
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 19 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 7 (July) to provide a full-year equivalent.

Purple line rises = years better than average; falls = years worse than average.
Peak (best year) Trough (worst year) Growth periods Decline periods
Population peaked around 2011, reaching above average levels. The lowest population point occurred near 2001, 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
