Range & Status
A largely Mediterranean species at the northern limit of its distribution range in the UK. Found in short vegetation on coastal heaths, it is confined to the Lizard Peninsula. The record from Carn Ingli in Pembrokeshire has not been substantiated. Recent (2000) survey work has confirmed its presence in several new sites in addition to the original site where it was first collected in 1952. The species is vulnerable to fire and the creation of firebreaks and the removal of highly flammable Gorse Ulex spp. in the vicinity of the populations, together with the introduction of grazing where feasible, should diminish this threat.
