Rare (proposed as a future Red Data Book species) in bogs, fens, marshes, river-banks, damp areas and saltmarshes in parts of northern Wales and southern England, with records north to Yorkshire. In Hampshire recorded only from Matley Bog in the New Forest, where it has been described as common, but there are no records on the county database since 1984. Not recorded from the Isle of Wight to date. Wingspan 10-12 mm. One of several similar, rather nondescript gelechiids, which can only be reliably identified by dissection of the genitalia. Larva mines leaves of Common Cotton-sedge.
