Phyllonorycter platanoidella
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Phyllonorycter acerifoliella
(Maple Leaf-miner); Phyllonorycter geniculella
(Sycamore Leaf-miner):
ID pointers: The adult moths are mostly white with yellow or brown markings edged in black. They are very similar in appearance to two other Acer-feeding species, P. acerifoliella and P. geniculella, and can be difficult to distinguish without careful examination of specific wing patterns or gendet.
The central fascia on forewing forms an obtuse angle, cf 90 degree angle on P.acerifoliella. The basal striae are placed alternately on P.joannisi c.f opposite each other on P.acerifoliella.
Distribution: (Last record: 30 October 2025 at Staveley ) – Uncertain very few records, most are leaf mines – DaNES – 5 records between 2001-2009; iRecord two records from Calke Park 2008 & 2023. First record of adult from Norton Lees on 4th July 2025, followed by the 2nd adult record from Chaddesden 16/7/2025 / Leaf Mine discovered 23/9/2025; leaf mine Staveley 30/10/2025
General Comment: Notes by Christian Heintzen on image dated 23/10/2025 – on Norway Maple (Acer platanoides) (A) > inflated lower surface tentiform mine with multiple small creases (B.2), between two lateral veins
Mine Period Additional:
Mine ID Difficulty:
– Easy to identify, generally the leaf mine is distinctive and unlikely to be confused with other species. Mine Type/s: Blister
Mine Feeding Method/s: Leaf Fold
Mine Comment: A largish rounded mine on the underside of a leaf between veins. The mine looks like a rounded blister with small creases to the underside.

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.
