– Rare / Uncommon / Scarce
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Scarce Chocolate Tip
ID pointers: An unmistakable species that gets its name from the well defined chocolate coloured blotch at the tip of the forewing. The blotch stops abruptly at the outermost cross-line which distinguishes it from the Scarce Chocolate Tip whose blotch extends beyond it.
Distribution: (Last record: 10 May 2025 at Melbourne ) – A resident species that is generally very rare in Derbyshire and seems to be almost totally confined to the south of the county. It has been expanding its range within the southern region since 2007.

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: Clostera curtula
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 7 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 8 (August) to provide a full-year equivalent.
ⓘ
Purple line rises = years better than average; falls = years worse than average.

Population peaked around 2010, 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
