A not so common species in Belgium, only known from the northern half of our country.

The larva makes a silvery long and sinuous gallery with a dark central frass trail, ending at the leaf margin, usually on the upper surface of Populus alba and P. canescens. Pupation in a cocoon under a silk membrane in the leafmargin, which folds over it.

The adults fly in two generations in July and again from late August till September.
