– click for General Verification Guidelines | – click for Specific Verification Guidelines Verification Notes: Rather than lose this record of an adult, along with records of the leaf-mines, we have created an aggregate 4.079X Zimmermannia atrifrontella/ longicaudella – the data is also entered to the aggregate.
– Significant Record / Very Rare / Vagrant 
– Leaf-miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Zimmermannia longicaudella
ID pointers: A greyish-brown fairly plain looking forewing which has a speckled apearance due to dark tipped scales. A black head and white thorax.
Distribution: (First record: 12 August 2025 at Norton Lees ) – (Last record: 24 January 2026 at Hall lane Ponds, Markham Vale ) – A possible first record for the VC57 Derbyshire recording area. An adult taken at light in Norton Lees on 12th August 2025. Leaf mines were discovered under the bark of an Oak tree at Hall Lane Ponds, Markham Vale on 24th Jan 2026 but mines must be entered to Zimmermannia atrifrontella/longicaudella, as they are indistinguishable from each other. Z. atrifrontella is the most likely contender, due to Z. longicaudella’s very limited range.
General Comment: Rather than lose this record of an adult, along with a record of the leaf-mines, we have created an aggregate 4.079X Zimmermannia atrifrontella/ longicaudella – the data for this record is also entered to the aggregate page. Unfortunately the recorder wasn’t able to obtain a Genitalia Determination as the species is a CAT4, so record was set as unable to be verified.
Mine Period Additional: The mines are indistinguishable from longicaudella and need to be recorded as aggregate Zimmermannia atrifrontella/longicaudella
Mine ID Difficulty:
– Mine cannot be identified without breeding through and then adult may need to be examined by Gen Det Prep. 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.
