– Uncertain/Unknown – Insufficient Data 
– Leaf-miner 
– Day-flying
– care required in the identification process, as confusion with similar species is likely – quality photographs required. ID pointers: One of the easiest Eriocrania species to identify. The forewings are typically metallic purple with a conspicuous silvery-white tornal spot, which distinguishes it from similar species that usually have golden spots.
Distribution: (Last record: 19 April 2026 at Markham Vale ) – Uncertain due to insufficient data – 1970 Hellbank Plantation; 8/4/2026 Longdendale adult photographed. Leaf Mines and tenanted mine discovered at Markham Vale 19/4/2026
General Comment: None Mine Period Additional: None.
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: Blotch
Mine Feeding Method/s: Not Recorded
Mine Comment: The larvae create a Blotch Mine commencing at the leaf edge. The mine contains characteristic “spaghetti-like” frass in long, tangled threads. The larvae have a dark brown or black head and two dark spots on the first thoracic segment.

This chart summarises all available historical occurrence records collated by ISO week of the year. It reflects recorder effort and sampling distribution as well as true biological activity, and should be interpreted as an indicative pattern of seasonal occurrence rather than a statistically controlled abundance or phenology model.

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.
