Nationally scarce (Nb) in saltmarshes throughout much of England and Wales, predominantly coastal. In Hampshire virtually restricted to the coast in the south-east of the county (it is regularly reported from the Southsea area), with just a handful of records on the Isle of Wight, predominantly along the north-west coast. The absence of records along the New Forest coast is surprising and fieldwork there could be rewarded. Wingspan 8-9 mm. Larva mines leaves of Sea Aster.
