ID pointers: Another tiny white moth, with an obvious golden basal streak running through the centre of the forewing towards the apex. Several golden markings in the apex area along with a black spot. Also darker brown edges to the golden markings.
Distribution: (Last record: 28 October 2025 at Staunton Harold Reservoir ) – Not listed in Harrison & Sterling 1988 – Current status unknown – Nationally local and uncommon – Few Derbyshire records but could be under-recorded
Leaf Mine 28/10/2025 Staunton Harold Reservoir.
General Comment: Species Complex and Identification Challenges – Recent research, including DNA analysis, has revealed that what was previously identified as a single species in the UK is actually a complex of four distinct but visually similar species: P. saligna (sensu stricto), P. asiatica, P. ramulicola, and P. triandricola.
Due to this complexity, positive identification of adults usually requires the dissection of female genitalia, as males are currently indistinguishable by this method. The morphology of the larval mines is also being studied to assist with identification.
Mine Period Additional: None.
Mine ID Difficulty:
– Mine cannot be identified without breeding through and then adult may need to be examined by Gen Det Prep. Mine Type/s: Gallery
Mine Feeding Method/s: Leaf Fold
Mine Comment: A tortuous lower epidermal mine with a central brownish frass-line. The larva then mines into the petiole and subsequently into a second leaf, normally opposite, where it creates another similar epidermal mine. Apparently P. saligna/asiatica – ongoing work Nationally to provide some clarity on supposed food-plant separation (asicatica on crack/white/weeping willows etc, saligna only on Purple Willow?). The larva may leave one leaf via the petiole to mine the bark of a twig before entering a second leaf to continue feeding and eventually pupate in a fold at the leaf edge.

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: Phyllocnistis saligna
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 22 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 9 (September) to provide a full-year equivalent.

Population peaked around 2018, 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
