– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Other Pugs (Eupithecia spp.)
ID pointers: A reddish band at the base of the abdomen helps to identify this small, otherwise grey-brown pug. Rather nondescript in markings with faint cross-lines and a weak, sometimes absent, discal spot.
Distribution: (Last record: 2024 ) – A resident but locally distributed and uncommon in Derbyshire. It was once widespread in the county, but in 1986 was only known from one site situated in the south of the county. During 2008 it was being reported from an area around Carsington Reservoir and may well be spreading from that area, hence the below record from Belper, during August 2013, an unusual date.

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: Eupithecia haworthiata
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 21 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 10 (October) to provide a full-year equivalent.

Population peaked around 2020, reaching above average levels. The lowest population point occurred near 2024, 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
