35.114 [B&F: 0812] Scrobipalpa instabilella (Douglas, 1846)

 

Nationally scarce (Nb) on saltmarshes, mud-flats and estuaries along parts of the coast of England and Wales, uncommonly in Scotland and Ireland. In Hampshire widely distributed along the coast from Hurst Castle in the west to the eastern side of Hayling Island. Not recorded from the Isle of Wight since 1926. Wingspan 12-14 mm. S. instabilella can be confused with S. salinella, although they can be distinguished by small but constant differences in their genitalia; some examples of S. samadensis can also be similar, but S. instabilella generally has more heavily marked stigmata (MBGBI Vol 4 part 2). Larva mines leaves of Sea-purslane, Grass-leaved Orache, Sea Aster and Glasswort.
