Notes:
Nationally scarce (Nb) on vegetated shingle and in salt-marshes along parts of the coast of southern England. In Hampshire fairly frequently recorded, from Hurst Castle in the west, to Hayling Island in the east. Not recorded from the Isle of Wight since the mid 1970s. Wingspan 11-15 mm. Most likely to be confused with S. atriplicella, but more contrastingly marked with angulate fascia at about three-quarters (MBGBI Vol 4 part 2), while S. instabilella generally appears darker and S. nitentella greyer than S. ocellatella. Larva mines leaves of Sea Beet.
