Vulnerable (proposed as a future Red Data Book species) and endemic to the British Isles, frequenting salt-marshes in Hampshire, Isle of Wight, Sussex and Dorset. First discovered near Southampton Water in 1937, feared lost when the original site was destroyed in 1971, but rediscovered on a saltmarsh near St Helen's, Isle of Wight in 1973 and now known from several locations in and around the region, including Farlington Marsh and Hayling Island. Wingspan 10-11 mm. Easily mistaken for one of the Coleophoridae, identification often requires dissection of the genitalia. Larva feeds on flowers and seeds of Sea Couch.
