Female forewing is a creamy yellow-brown with darker, rather diffuse markings, including a rather oblique cross-band at about a third and another at about a half, with inner margin deeply indented.
Distribution: (Last record: 17 July 2018 at Kings Newton ) – Uncertain, likely to be widespread where there are flower meadows. Since 2004 only 10 records from Melbourne, Kings Newton, Belper & Newall. Latest 17/7/2018 Kings Newton.

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: Cnephasia longana
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 19 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 2012, 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
