A very rare species in Belgium, mainly in the southern part of the country.
The case is a lob case composed of leaf fragments. It is 7–8 mm and the mouth angle is 45°.
After overwintering the case has lost a part of the leaf fragments.
See also bladmineerders.be.
The larvae are making very little fleck mines.
The larvae live until June. To overwinter, the larvae look for hiding places like in a fork of stalk at the base of the bush.
The adults fly in June and July.
