– Uncertain/Unknown – Insufficient Data 
– Leaf Miner 
– Day-flying
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Incurvaria masculella
ID pointers: Easily confused with I. masculella – The males of this species have simple antennae – An attractively marked little moth. The yellowish marking on the costa is closer to the wing tip. If present on masculella it is closer to the head than the opposing tornal spot.
Distribution: (Last record: 22 February 2025 at Longdendale, Wildboar Clough ) – Uncertain due to few records – One in 1971 then two in 2024 – likely to be found in localised colonies on the upland moors where there are Bilberry and Cloudberry growing.
General Comment: None Mine Period Additional: The larvae feed on bilberry and cloudberry, and at first they mine the leaves creating a small blotch mine elongated to form a linear mine, then cut out a portable case and dropping to the ground. Here they feed on dead leaves.
Mine ID Difficulty: Not Recorded
Mine Type/s: Not Recorded
Mine Feeding Method/s: Not Recorded
Mine Comment: None.

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.
