Blue –  Generally Common / Widespread   
Taxonomy:   Macro   >>  Noctuidae  >> Xyleninae
ID Difficulty:  Red – difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.
Confusion Species: Saltern Ear Moth, Ear Moth
ID pointers: Be aware of the Ear Moth – The ‘Ear’ moths are much alike so making positive ID difficult. Gen-Det is required to be 100% on ID. The Ear moth trio is very difficult to identify, so records of Saltern Ear and Ear Moth, it is recommended they are recorded as Ear Moth agg, unless there is evidence to support the record otherwise.
Distribution:  A resident that appears to be locally common and widely distributed and primarily across the upland moors of North Derbyshire. This specimen was trapped on August 22nd 2020 and identified by Gen-Det per Steve Orridge and Mike Dale
Flight Period: August /  September /  –  On the wing August – September Moth Activity: Nocturnal   – and is attracted to light Photographed: Yes –  Photographed By: Mike Dale  © All Rights Reserved

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: Amphipoea lucens
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 23 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.
Peak (best year) Trough (worst year) Growth periods Decline periods
Population peaked around 2005, reaching above average levels. The lowest population point occurred near 2020, 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
