– Generally Common / Widespread 
– Leaf-miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: < Parornix anglicella /Parornix scoticella >
ID pointers: All parornix species require particular care in identification. Adults are all similar to each other and are best determined by either gen-det or by rearing through the food plant. They all have a distinctive resting posture with the front part of the body raised on the forelegs, and a slightly up-curved rear.
Distribution: The species is nationally common in Britain and so it is likely to be common where the food plant is. More likely that the mine is discovered.
General Comment: None Mine Period Additional: The larvae feed on hazel (Corylus avellana), initially creating a squarish blotch on the underside, and then folding over the edge of the same, or a nearby leaf.
Mine ID Difficulty: Not Recorded
Mine Type/s: Not Recorded
Mine Feeding Method/s: Not Recorded
Mine Comment: None.

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.
