– click for Specific Verification Guidelines
Verification Notes: Good photos required of adult/leaf mines to support the record. Confusion species is Stigmella freyella but this has not been recorded in Britain so far.
– Uncommon / Scarce
– Leaf-miner
– care required in the identification process, as confusion with similar species is likely – quality photographs required.
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: Not Recorded
Mine Comment: The distinctive larvae feeds on Bindweeds during July-August and September. Firstly making a narrow gallery mine that is filled with frass. Then makes large translucent yellowish blotch mines, from here the frass is ejected. The science is interesting as the larvae make silken threads underneath the leaves in which they move around.

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.
