Range & Status
Widespread across Europe to Russia, including the Channel islands (Heath & Emmet, 1985) but known in Britain only from Cornwall. There are inconclusive records from other localities (Smith, 1983). Specific status uncertain, it may be just a bisexual form of the widespread Luffia ferchaultella .
Found only near Marazion (Smith, 1983), where it is confined to an area about 1 km long, on St. Michael' s Mount, where there is an extensive population, and also on rocks in between which are cut off by the tide. Possibly also at Kynance and Polzeath, where similar cases have been found but not reared.
Habitat & Ecology
Cornish records come from lichen-covered walls and rocks. The larvae feed on the following lichens: Parmelia glabratula (Lamy) Nyl., Ochrolechia parella (L.) Massal. and Caloplaca aurantia (Pers.) Hellbom.
Known to be parasitized by Ichneumonidae (Smith, 1983).
