Wingspan 15-19 mm.
Occupying dry sandy areas and distributed locally in the south-east of England, this is a fairly distinctive Gelechiid moth. It can be recognised by the noticeable dark and pale streaking and the pale-ringed dark spot on the forewing at two-thirds.
The larva feeds on dock (Rumex), particularly curled dock (R. crispus), feeding internally on the roots and stems.
The moths fly between June and August and are attracted to light.
