A not so common species throughout Belgium.
The larvae are thought to feed at first at flowers and or seeds of the food plant. It builds later a portable flat, elongate-ovate case constructed from leaf fragments and covered with soil particles and feeding on fallen leaves. Pupation in the larval case.
The adults fly in the sunshine and later come occasionally to light.
The adults fly in one generation a year: from late May till late June.
