Leaf-miner: CAT A – Recorded accepted without the leaf or a photo – Larval Case: C2 – Photo or specimen of larval case/plant required – 
– click for General Verification Guidelines | – click for Specific Verification Guidelines 
– Uncertain/Unknown – Insufficient Data 
– Leaf Miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Coleophora potentillae – Potentilla Case-bearer
Mine Period Additional: A robust case with a prominent ventral keel and excised leaf fragments added to the top of the case. These wear away with age.
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.
