A rare species in Belgium. More than likely that the species is underrecorded due to the difficult search for mines in the fruits of his food plant.
The egg is laid on a wing of the fruits of Acer platanoides.
The larva mines on a leaf-stalk in spring and on the wing of the fruits of Acer platanoides in summer. The monophagous larva of the summer generation makes a short gallery leading into the seeds.
