– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required. ID pointers: The adult moth has forewings that are golden-brown with characteristic shining white markings that are inwardly dark-edged.
Distribution: (Last record: 4 November 2025 at Rowlee Bridge, Woodlands Valley ) – Appears to be uncommon but probably under recorded – Leaf Mines are found and make up most of the records.
a good contender for an adult was recorded by Christian Heintzen at Glossop, April 2025.
General Comment: Notes by Christian Heintzen on image dated 4/11/2025 – on Birch (Betula) > 11 mm long lower surface tentiform mine with 6 creases in lower epidermis (a) > frass in one corner of the mine (b)
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: Blotch
Mine Feeding Method/s: Not Recorded
Mine Comment: The larvae create a distinctive blotch mine on the underside of a birch leaf, often small but puckers the leaf noticeably. The mine is small (8-14 mm long) and causes the leaf to pucker noticeably, often resulting in several (can be up to 6) creases in the lower epidermis. A small lower surface tentiform mine and all frass is in a corner of the mine.

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.
