– Significant Record / Very Rare / Vagrant
– easy to identify, generally distinctive and unlikely to be confused with other species.ID pointers: Looks like a geometrid species. A charcoal blackish-grey ground colour and creamy white spotting with weaker cross-lines are fairly diagnostic.
Distribution: (First record: 1955 at Ramcroft Colliery, Heath ) – (Last record: 18 July 2019 at Darley Dale ) – The status of this moth in Derbyshire is uncertain and possibly accidentally introduced. The species has been recorded on several consecutive years from a site in Darley Dale, near Matlock, close to a timber yard. There seems to be no other records in recent times, apart from 1955 and 1959 both from Ramcroft Colliery, Heath. A record from Ripley on 12/8/2012 (near a timber yard) and one new record from Long Eaton 2/7/2018. Last record from Darley Dale 18/7/2019. (photographed on iRecord).

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: Parascotia fuliginaria
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 10 (October) to provide a full-year equivalent.

Population peaked around 2003, reaching above average levels. The lowest population point occurred near 2003, 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
