Forewing is a dark brown, with a purplish sheen, with 3 whitish triangular shaped spots running along the edge of the costa and two on the dorsum.
Distribution: (Last record: 26 August 2025 at Norton ) – Likely to be uncommon with less than 10 records, majority of which are from the south of the county. Found where there is a good density of apple trees. Latest record 26/8/2025 – Norton leaf mine / latest adult 27/5/2018 Allestree
General Comment: None Mine Period Additional: None.
Mine ID Difficulty:
– Care required in ID process as confusion with similar leaf mines. Quality photos of the mine required. Mine Type/s: Gallery, Blotch
Mine Feeding Method/s: Leaf Fold
Mine Comment: The larvae first of all mine the leaf creating a gallery, which leads to a semi-translucent, often orange-brown, blotch-shaped mine on the upper surface of a leaf. After this stage, the larva vacates the mine and creates two or three successive folds along the leaf margin, secured with silk, where it continues to feed and skeletonize the leaf’s interior.

This chart summarises all available historical occurrence records collated by ISO week of the year. It reflects recorder effort and sampling distribution as well as true biological activity, and should be interpreted as an indicative pattern of seasonal occurrence rather than a statistically controlled abundance or phenology model.

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.
