– Day-flying
– easy to identify, generally distinctive and unlikely to be confused with other species.ID pointers: The forewing is attractively marbled in greys, blacks and silvery markings. There is an obvious creamy, silvery white “Swiggle” marking in the central forewing and a zig-zag black cross-line along outer edge are all diagnostic features.
Distribution: A resident that is locally common on the upland moors of Derbyshire. The eastern moors from Froggatt to Matlock are the prime areas for this species, with scattered records further northwest. The moth flies in the day as well as night. Specimens outside of the main area are considered to be strays or vagrants.

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: Syngrapha interrogationis
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 10 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 8 (August) to provide a full-year equivalent.
ⓘ
Purple line rises = years better than average; falls = years worse than average.

Population peaked around 2013, reaching above average levels. The lowest population point occurred near 2006, 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
