The larva makes a conspicuous, whitish blotch mine in the food plant. The summer brood also in Phragmites.
Pupation takes place on a leaf or stem, under a gurdle, often on the mined leaf, just below the mine.
The adults come to light.
The adults fly in two generations a year: from the end April till the end of June, and from early July till mid September.
