The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Sparsely distributed across southern Britain, rarest in west.
Discovered in Cornwall by D.A. Sheppard at a site on the Lizard Peninsula (1981) and recorded more recently (1997) at Kennack Sands by Ian Hoare.
Habitat & Ecology
Localities tend to be coastal or south-facing calcareous grassland, suggesting a need for warm micro-climates. The foodplants have not been identified but are
believed to include Black Bog-rush Schoenus nigricans in marshy situations and sedges Carex spp. such as Glaucous Sedge Carex flacca .
Agricultural improvement of the semi-natural grasslands of the Lizard Peninsula.
Abandonment of grazing, leading to coarsening and scrub development.
Much of the remaining undisturbed Lizard grasslands are now protected by The National Trust, Natural England and the Cornwall Wildlife Trust.
