– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: M.epilobiella
ID pointers: A distinctive orange and yellow Mompha, and as with all the Mompha species they are colourful, attractive and distinctive. They rest low and flat in a horizontal position. Often have scale tufts.
Distribution: (Last record: 13 June 2025 at Belper ) – Appears to be uncommon as very few records. It favours Great Willow herb and is probably widespread across Derbyshire as this species occurs widely throughout much of Britain. Most likely under recorded

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: Mompha ochraceella
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 14 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 9 (September) to provide a full-year equivalent.

Population peaked around 2025, 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
