Range & Status
A very local species but widely distributed in southern England and south Wales. Generally encountered in small numbers, but occasionally (as in some Cornish sites) the species is quite numerous. The presence of Scabious (especially Field Scabious Knautia arvensis ) is a prerequisite. Most of Cornish records are from coastal areas associated with dune systems on the north coast from Upton/Gwithian Towans to Trebetherick near Rock. It is also fairly common just inland from the coast, where Field Scabious grows in hedges and roadside verges. The Cornish sites are now of national importance due to the recent, rapid, decline of the species in other parts of the country.
