Only known in Britain from southern England and Cornwall.

Regional Distribution

Confusingly known from both Whitsand Bay in east Cornwall and Whitesand Bay in west Cornwall. Also reported from Bishop' s Wood (Clark, 1906). Most recently found at Nanjizal in 1923 by R.T. Bannister and The Lizard in 1927 (Keys, 1928).

Habitat & Ecology

Associated with the nests of the ants Formica fusca , Myrmica rubra and probably other species, in dry sandy grasslands on sea cliffs.


Agricultural improvement of semi-natural grasslands; abandonment of grazing, leading to coarsening and scrub development.


Protection of clifflands from development, and maintenance of grazing.
