Observed for the first time in Belgium in 2018 in LG.
Native
Greyish yellow.
Starting as a rather short, narrow, epidermal serpentine gallery on the underside of the leaf, the mine broadens into a small triangular blotch, most of the time in a vein axil.
See also gracillariidae.net.
Pupation in a yellowish transparent cocoon.
Later instars leave the mine and feed freely from a cone or a downwards folded leaf edge.
The adults fly in two generations a year emerging during June, overwintering, and then flying until May.
The species lives mainly on Acer monspessulanum, but has also been observed on Acer pseudoplatanus.
