Range & Status
The exact status of this species in Britain is difficult to determine because of its similarity to the commoner coastal species Phycitodes saxicola (Vaughan); the separation of these two species was not published until 1937 (Pierce, 1937). The only confirmed post-1970 British records are from Cornwall (Parsons, 1993), in 1993 from the Isles of Scilly, in Norfolk in 1993, and in 1994 (B.F. Skinner, pers. comm.) and from Dorset. This species is widespread on the Continent.
Recorded at Lamorna in 1979 (Agassiz, Heckford & Langmaid, 1992); there are previous records from Redruth. This species might be common but overlooked in Cornwall in suitable coastal habitat. Also recorded on St. Mary' s in 1993 (Heckford, 1994b).
Habitat & Ecology
The larvae feed on Sheep' s-bit Jasione montana (Heckford, 1998).
