– Uncertain/Unknown – Insufficient Data 
– Leaf Miner
– care required in the identification process, as confusion with similar species is likely – quality photographs required. ID pointers: The adult’s forewing is a brownish yellow, with the costa, the termen and the dorsum area darker brown, giving it a distinctive appearance.
Distribution: (Last record: 29 November 2025 at Glossop ) – Nationally common. Status in Derbyshire unclear as very little data. The mine has been reported from various locations but only a few records each year so local in places throughout the county. The species is possibly on the edge of its distribution here in Derbyshire.
General Comment: Coptotriche marginea -29th Nov 2025 -Glossop – Christian Heintzen – on Bramble (Rubus) (A) > finely wrinkled (a) opaque pale brown upper surface blotch without frass (B) > second generation larva active throughout winter period (a) > frass ejection through exit whole(s) in lower epidermis ©
Mine Period Additional: Mine – June and September to March – especially visible in February and March.
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 larva creates a characteristic “funnel-shaped” blotch mine in the leaf. The mine starts as a short corridor that widens into a long, elliptical, whitish to yellow-brown blotch. The autumn generation of larvae feeds throughout the winter within the mine. All frass is ejected through a small opening on the underside of the mine. The larva is also pretty distinctive – looks a bit like a green Michelin Man. It’s black head can be seen in the photo of the bramble 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.
