** Identification write-up required
**
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Parornix finitimella (Southern Blackthorn Parornix); Parornix devoniella (Hazel Parornix)
ID pointers: The adult moth is generally dark fuscous (dark brownish-grey) with white markings and distinctive pure white labial palps and frons (forehead), which help distinguish them from other similar Parornix species. CAT 4 – requires a GenDet for ID of adult moth
Distribution: (Last record: 30 August 2025 at Shirland ) – Uncertain due to insufficient data – Only 7 records between 1920 – 2011 – latest – leaf mine from Shirland 30/8/2025
General Comment: None Mine Period Additional: None.
Mine ID Difficulty:
– Care required in ID process as confusion with similar leaf mines. Quality photos of the mine required. Mine Type/s: Blotch
Mine Feeding Method/s: Leaf Fold
Mine Comment: The larva creates a brown blotch mine on the underside of the host leaf, subsequently living under a silken membrane that folds or puckers the leaf edge. The pupa overwinters in a cocoon, often within a folded leaf on the ground.

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: Parornix scoticella
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 2025, reaching above average levels. The lowest population point occurred near 2011, 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
