Nationally scarce (Na) on shingle beaches and sandy beaches in western Scotland. Unlikely to be recorded in Hampshire or on the Isle of Wight. Wingspan 13-15 mm. Superficially resembles S. pauperella
and some forms of S. acuminatella
but with pale markings along veins and lack of any red-brown coloration (MBGBI Vol 4 part 2). Larva feeds within stems of Curled Dock, over-wintering as a pupa.
