Previously considered as a synonym of
S. salinella which is now considered a separate species and not found in western Europe.
Nationally scarce (Na) and difficult to find in saltmarshes on the southern and eastern coasts of England, from Cornwall to Lincolnshire; Co. Durham; Lancashire; Pembrokeshire, south Wales; in Scotland, East Lothian and Nairn (MBGBI Vol 4 part 2). In Hampshire and on the Isle of Wight mainly recorded from the Portsmouth area, with a few elsewhere on Hayling Island - on the Island there is an old record from Newtown and recently uncovered in the Shanklin area. Wingspan 11-15 mm. Most likely to be confused with
S. instabilella, but some examples can be mistaken for
S. atriplicella, or
S. obsoletella; an unusual form of
S. suaedella is similar to
S. salicorniae, but the stigmata are usually much smaller and more indistinct in
S. suaedella (MBGBI Vol 4 part 2). Larva mines leaves of Glasswort, Sea Aster and Annual Sea-blite.
