(Staudinger, 1870)Wingspan 8-10 mm.
Since its discovery in London in 1989, this species has slowly spread through the Southern counties of the UK and into the West Country and Midlands.
The food plant of the larvae is London plane (Platanus x hispanica). It is because of this foodplant that the moth will inevitably have a more surburban distribution.
The moths fly in late April to May and in August.
The mines formed by this moth in October and November are large and very distinctive, with several mines often appearing on one leaf.
