– care required in the identification process, as confusion with similar species is likely – quality photographs required. ID pointers: Appears like a miniature version of Riband Wave. A single black spot appears in the middle of each wing.
Distribution: (Last record: 22 July 2024 at Staveley ) – Resident in Derbyshire but is very locally distributed and scarce being confined to a few sites in the Trent Valley. Added to the county list in 1954. There seems to be a good localised colony in the central SE area (Long Eaton/ Breaston/ Sandiacre) of the county, with small numbers regularly recorded throughout the flight period. During 2019-2023 37 reports of 55 individuals from eight sites.

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: Idaea fuscovenosa
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 12 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.

Population peaked around 2019, reaching above average levels. The lowest population point occurred near 2018, 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
