Wingspan 11-15 mm.
Occurring locally in England and Wales and parts of southern Ireland, this moth inhabits a variety of open habitats.
It is on the wing from June to September and is mainly nocturnal. The adults are similar to several other species and are best identified by reference to the genitalia.
The larval foodplants are mainly orache (Atriplex) and goosefoot (Chenopodium). In its later stages, the larva creates a case made from silk and specks of plant material or droppings.
