Black – Uncertain/Unknown – Insufficient Data        purple – Leaf Miner
Taxonomy:   Micro   >>  Nepticulidae  >> Nepticulinae
Other Name/s: Coarse Hazel Pigmy
ID Difficulty:  Red – 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.
Flight Period: May /  August /  –  Two generations in May and August Mine Period: June /  July /  September /  October /   – The first stage of the mine is filled with Frass. The best means of identification is the position of the egg within the mine. The egg is always laid in a vein axil on the underside of a leaf, this helps to identify it from S.microtheriella which most often lays its egg in a vein but not in the axil (A leaf axil is the angle or space fromed where a smaller vein branches off from a larger vein on a leaf). The mines are often found alongside S.microtheriella on the same leaf. Moth Activity: Cathemeral   – active in afternoon and evening sunshine and occasionally comes to light Photographed: Yes –  Photographed By: Martin C Harvey  © All Rights Reserved

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.

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: 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 7 (July) 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 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
