A recent (2018) addition to the Belgian fauna, still very rare and local.
The mine is a long slender contorted gallery in which the black frass is in a central line from start to finish. Several mines per leaf is not exceptional.

Mines can be found from June to July and again from August to November.
This species has two generations a year.
