Blue –  Generally Common / Widespread        purple – Leaf Miner
Taxonomy:   Micro   >>  Incurvariidae  >> Incurvariinae
Other Name/s: Feathered Leaf-cutter
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
Confusion Species:  Incurvaria pectinea
ID pointers: Unusual amongst the micros, the male has feathered like antennae. The head is orange-yellow, with forewing a dark brown, sometimes tinged purplish, with a distinct triangular whitish spot, half way along the dorsum, and a similar smaller one at the tornus.
Distribution:  Fairly common across the British Isles. Derbyshire status unknown, but likely to be locally common.
Flight Period: April /  May /  Mine Period: April /  May /   – May & June – mines are very similar to I.pectinea Photographed: Yes –  Photographed By: Will Soar  © All Rights Reserved

Wingspan: 12-16mm
 Food Plant: Hawthorn and roses as well as other herbaceous plants and bushes.

If the Map Layers function fails, just refresh the page and it should be OK after. Use the +- zoom on the top left, or on a tablet, use two fingers to zoom. Remember, the last layer you ticked is the one which displays the popup information - they sit on top of each other - de-select then re-select, to see the popup values.

******* Choose ONLY one at a time, of either Monad, Tetrad or Hectad Distribution - each has it's own set of data. Also, the distribution maps cover ALL recorded data. *******

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.

Land-cover * shows the variety of land-cover within the VC57 area, based on the CORINE (Coordination of Information on the Environment) forty-four thematic classes of land-cover. This will show, to a greater or lesser degree, the number and variety of moths found in different land-cover types. The UK continues to operate within the Copernicus programme, with the UK Centre for Ecology & Hydrology (UKCEH) providing Corine Land Cover (CLC) datasets for the UK and its territories.

CUSUM Analysis: Incurvaria masculella
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 13 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.
Peak (best year) Trough (worst year) Growth periods Decline periods
Population peaked around 2004, reaching above average levels. The lowest population point occurred near 2023, 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
