[= Phyllonorycter platanoidella]
Wingspan 7-8 mm.
In common with other Acer-feeding Phyllonorycters, this species is mostly white with yellowish or brownish markings edged black.
The foodplant is Norway maple (Acer platanoides), the larval mine being a fairly large roundish blotch on the underside of the leaf.
The species is commonest in south-east England, but is expanding northwards and has recently been found as far north as Yorkshire.
May and August are the flight periods for the two generations of adults.
