Brown –  Significant Record / Very Rare / Vagrant         purple – Leaf Miner
Taxonomy:   Micro   >>  Tortricidae  >> Olethreutinae
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
Confusion Species:  Spilonota ocellana
ID pointers: Please note Spilonota laricana was formerly thought a rather dark but distinctive form of Spilonota ocellana but is now a distinct species, separated with care by more extensive grey suffusion over half the wing and more extensive black dashes. However, a dark form of S. ocellana also occurs, where the paler areas of the wing are all darkened. S. laricana retains the pale dorsal central area. S. ocellana also has a broader forewing.
Distribution:  (First record: 18 July 2017 at King's Newton )  –  (Last record: 22 July 2024 at Tor-side reservoir )  –  Appears to be only two records of this species which was formerly considered to be a form of Bud Moth (Spilonota ocellana).One from Kings Newton 18/7/2017 So this potentially a first record for the VC57, and one recorded from Tor-side Reservoir, Derbyshire in July 2024. 
Flight Period: June /  July /  August /  –  On the wing June-August.  – The larvae mine the needles of the food plant then overwinter and feed on the yooung buds in the spring. Moth Activity: Nocturnal   – and is attracted to light Photographed: Yes –  Photographed By: Christian Heintzen, Will Soar  © 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.

******* 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: Spilonota laricana
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 23 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 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
