– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: S.microtheriella and M. tityrella
ID pointers: An overall light brown or greyish upper-wing covered in coarse yellowish or silvery scales. A light orange-pale yellow head and a pale cross-band at about a third, bordering the darker final third of the wing. Whitish cilia.
Distribution: (Last record: 5 November 2024 at Burton-upon-Trent ) – With few records of any adults and most relate to the Leaf mines, the species is obviously present in the county in wide scattered localities but relatively uncommon.

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: Stigmella floslactella
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 8 (August) to provide a full-year equivalent.

Population peaked around 2001, reaching above average levels. The lowest population point occurred near 2001, 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
