– Leaf-miner
** Identification write-up required
**
– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Phyllonorycter tristrigella (Elm Leaf-miner); Phyllonorycter nicellii (Hazel leaf-miner)
ID pointers: The adult moth features a distinctive “striped” appearance, with patterns fading from whitish to chestnut to black.
Distribution: (Last record: 7 October 2023 at Calke Park ) – Uncertain due to insufficient data – Probably locally common – Harrison & Sterling lists 4 records to 1985; DaNES 9 records from 2001-2010 all leaf mines; iRecord two in 2023 from Calke Park of Leaf Mines.
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: Blotch, Blister
Mine Feeding Method/s: Leaf Fold
Mine Comment: The larvae primarily feed on the leaves of the common alder and grey alder. The larvae create a long mine on the underside of the leaf, typically running between two veins and often extending from the midrib to the margin. The lower epidermis of the mine appears smooth. Multiple mines can often be found on a single leaf.

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.
