Davey, P., 2009: A local species of coastal sandhills in England and Wales plus two sites in Scotland, the larva feeding nocturnally on marram (Ammophila arenaria) and hiding in the sand by day. The moth is reputed to have a protracted emergence period between mid-June and late September. In Dorset, the moth is common to abundant amongst marram growing on the sand dunes facing Studland Bay and frequent in similar habitat both on Brownsea Island and on the northern periphery of Hengistbury Head. "It is a marvellous sight to see L. littoralis darting about in hundreds along the sandhills at a tearing pace: it is utterly impossible to net them except for an occasional lucky chance." (Reverend E Bankes, 29 June 1892). Short distance dispersal of a few kilometres has been noted at Arne and at Iford. The old record from the Chesil suggests that the site supported a colony many years ago; indeed, small quantities of marram in the Ferrybridge area remain to the present day. Marram was locally abundant between Bournemouth and Mudeford in the early part of the twentieth century, but it is now infrequent, and the old Shore Wainscot records from this area too, indicate the presence of strong colonies at that time. Marram, which is an important dune forming plant, is under pressure from human leisure pursuits on Chesil, Studland and Hengistbury Head. Some fencing has been erected to protect the marram on Studland, and such measures will doubtless be beneficial to the Shore Wainscot. It is recommended that conservation agencies responsible for managing reserves containing sand dune habitat, explicitly include this species in their management plans.
