Winter Moth       November Moth agg
70.107 BF1795  –  Geometridae –  Larentiinae – Epirrita dilutata – November Moth – (Denis & Schiffermüller, 1775) Adult Macro:  CAT 4 – Dissection required – Dissection required       PDF Icon – click for Adult Macro Verification Guidelines
Blue –  Generally Common / Widespread   
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: Pale November Moth, Autumnal Moth
ID pointers: The four species of Epirrita moth are notoriously difficult to ID in the field. Best to follow the information contained in the ID Guides. In some cases the moths genitalia needs to be inspected. However in fresh clearly marked (dilutata) individuals, the post-median line touches or bends towards the small black discal spot if present. In the Pale November Moth (christyi) the black discal spot is isolated.
Distribution:  A resident that is common and well distributed throughout the county. Can be very common locally.
Flight Period: September /  October /  November /  –  On the wing between September – November. Moth Activity: Nocturnal   – and is attracted to light Photographed: Yes –  Photographed By: Christian Heintzen  © All Rights Reserved

Wingspan: 38-44mm
Forewing: 15-20mm Food Plant: Broadleaved trees.

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: Epirrita dilutata
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 12 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 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
