Wingspan 8 to 9 mm. A small but brightly coloured species.  The larva mines the leaves of Goosefoot (Chenopodium) and Orache (Atriplex) and others in this family, forming a contorted gallery, usually with intestine-like loops.

Several species of fly also mine Chenopodiaceae and the mines can be similar

Frequenting gardens and cultivated land, open ground and wasteland.

The moths have two generations, flying in May and June, and again in August and September.

Distributed widely but locally throughout England, it is rare in Scotland and not known in Ireland or Wales. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.
