A rather uncommon species in Belgium.
Usually on the underside of the leaf.
The mine is a long sinuous gallery with a broad frass line throughout the mine. The mines are variable and are sometimes difficult to separate them from mines of Stigmella splendidissimella.

The cocoon is brown.
The adults fly in two generations a year: late April-May and July-August.
