A rare species in Belgium, though recorded from all provinces.
The egg is laid on a wing of the fruits of Acer pseudoplatanus.
Only the summer generation mines the fruits. A small gallery is visible but the mine does not enter the seed itself.

The cocoon is reddish and is spun on the trunk of the host tree.
The adults fly in two generations: June and August. They rest on the tree trunk and come to light.
The species mines the wings of the fruits of Acer pseudoplatanus and A. monspessulanum.
