Plane mining moth - Phyllonorycter=Lithocolletis platani | deutsch

Symptoms    Large-scale yellow brown or reddish brown spots on leaves, which are easily recognized as mines; they are produced by the larvae of the Plane mining moth and develop on the lower leaf surface. They can be mistaken especially for plane anthracnose, which often occurs together with the moth. For a safe diagnosis, a leaf should be held against the light, and the mines can be seen easily. By use of a hand lens also the dark feces within the mine are showing. After hatching, the outer layers break off and the mined tissues become free.
Impact    Nearly no damage, at most premature leaf shedding
Control    Control mostly not necessary; in special cases use of a skinning inhibitor (see Official Register of Plant Protection); with single standing planes collecting and removing the leaves in autumn can reduce the itensity of mines in the following year.
