– Significant Record / Very Rare / Vagrant 
– Leaf Miner 
– Day-flying
– care required in the identification process, as confusion with similar species is likely – quality photographs required. ID pointers: An overall greyish-brown forewing that often shows a violet reflection. It lacks the white tornal spot of P. filicivora
Distribution: (Last record: 16 November 2025 at Ticknall Lime Yards ) – One record from 1892 – Wirksworth (Harrison & Sterling 1988) – two records from DaNES Historic – 15/3/2010 & 22/3/2010 – Despite plenty of the food plant in various sites in the south of the county, there should be more records.
General Comment: None 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: Not Recorded
Mine Feeding Method/s: Case
Mine Comment: The larvae initially mine the leaf fronds of Ferns in particular Hart’s-tongue Fern and Spleenwort, but after hibernation, live freely in a portable case made from empty sporangia (spore bodies) on which they feed. This case resembles a displaced sorus (spore cluster) on the underside of the leaf. Larvae are yellowish-white with a black head, prothoracic shield, and anal plate, a key feature distinguishing them from P. filicivora, which has a paler head.
