– Uncertain/Unknown – Insufficient Data 
– Day-flying
– easy to identify, generally distinctive and unlikely to be confused with other species.ID pointers: The males are relatively dull brown, including a diffuse basal patch and have bipectinate antennae, the females have more distinctive chestnut brown markings on a whitish to greyish-buff ground colour.
Distribution: (Last record: 24 March 2025 at Glossop ) – Nationally Scarce B – A characteristic species of the gritstone moorlands.Rarely recorded away from this habitat in Derbyshire. But so few modern day records. Would suspect locally common in the recording area on the heather moorlands.

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: Philedonides lunana
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 20 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.

Population peaked around 2025, reaching above average levels. The lowest population point occurred near 2021, 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
