A very rare and local species in the north of Belgium.
Native
Wingspan 11–15 mm.
The early instars starts mining the leaves producing a U or horseshoe-shaped mine, later it lives among spun leaves where it furthers mines the thickness of the leaves, or it consumes the unripe seeds which are spun loosely together. Pupation takes place in a cocoon on the ground where it overwinters.
The adults become active before sunset and later come to light.
The adults can be seen from late May till early September. Normally univoltine, but regularly a small second generation appears.
The larva feeds on a large variety of Chenopodiaceae like different species of Atriplex, Chenopodium and Suaeda. Also reported from Salicornia europaea, Beta maritima, Salsola kali.
It inhabits salt marshes and xerothermic halophytic vegetation.
