– Generally Common / Widespread
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: D. abietella
ID pointers: There is considerable uncertainty to the status of the four Dioryctria species in Britain, as they are very difficult to tell apart. In particular, D. abietella and D. simplicella both are associated with pine. There is also some size overlap with D.sylvestrella, both being the largest of the four Dioryctria species.
Distribution: A species that has spread into the county due to the commercial planting of Pine, so likely to be common wherever there are Pine plantations.

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.

CUSUM Analysis: Dioryctria abietella
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 12 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 2008, reaching above average levels. The lowest population point occurred near 2007, 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
