Phyllonorycter geniculella is a moth of the family Gracillariidae. It is found from Sweden to the Pyrenees, Italy and Bulgaria and from Great Britain to southern Russia.

The wingspan is about 8 mm. There are two generations per year with adults on wing in May and again in August.[2]

The larvae feed on sycamore (Acer pseudoplatanus) mining the leaves. The mine starts as an inconspicuous lower surface epidermal corridor. This corridor is followed, and mostly replaced, by a relatively small, lower-surface, tentiform mine with many weak folds. If the mine is located near the leaf margin, the leaf may fold downwards over the mine. The frass is deposited in a corner of the mine. The pupa is formed in the mine and is dark brownish black. It is made in a loosely spun cocoon.[3]
