A very rare and local species in Belgium.
Wingspan: 10–14 mm. In the very similar species Prochoreutis sehestediana, the white spots are less clear and also arranged a little differently. This species has also a light brown subterminal fascia that is missing or not so obvious as in P. myllerana.

The larvae are first mining, later living in a loose spinning in a shoot or between two leaves. It is not known how the winter is passed, but most probably in the adult stage, because the usual food plant is often flooded during winter and would not produce sufficient growth in early spring to support larvae.
The moths are active during the day, flying over the food plant and later come to light.
The adults fly at least in two generations per year: from late May till July and again from August to early September.
