Taxonomy:   Macro   >>  Zygaenidae  >> Procridinae
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
Confusion Species:  Cistus Forester
ID pointers: There are two species of British Forester moth found in Derbyshire. The Cistus is the smaller of the two, and therefore more easy to identify. The upper wing is a bright emerald green, although the image below depicts a rarer “blue form”. The Forester has long narrow and less rounded forewings than Scarce Forester, which is not found in Derbyshire. The antennae of the male are blunt and thickened at the tip. The food plant is critical when identifying the two species of Forester in the county.
Distribution:  (Last record: 23 June 2024 at Holloway, Matlock )  –  A scarce species, and up until 2018, there were only four or five known colonies in Derbyshire. During period 2013 – 2018 there were 10+ individuals recorded from three of the sites. In the following period 2019 – 2023, five records of nine individuals from five new sites were recorded. Four records in 2024 that have been accepted.

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.

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: Adscita statices
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 10 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 2005, 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
