Acanthiophilus helianthi

Range & Status

Throughout southern Britain but very localised.

Regional Distribution

Eight sites known, along the north coast, including Porth Joke and Glebe Cliff, Tintagel.

Habitat & Ecology

Associated with unimproved grasslands where management encourages good flowering and seed-set of Black Knapweed Centaurea nigra and other herbs, the larvae developing in the seed heads.

Threats

Heavy grazing, which leaves sward short, but also undergrazing which allows coarsening and scrub development.

Conservation

The Glebe Cliff site is owned by The National Trust.
