Cornish Red Data (2009)

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.

Lionychus quadrillum - A ground beetle



Range & Status

Always very localised in Britain, but has become increasingly scarce.

Regional Distribution

Reported from several localities in Cornwall: Swanpool (Clark, 1906), Downderry, Whitsand Bay (Willcocks, 1915; Keys, 1918), Looe Bay in 1919 by J.H. Adams, and Loe Bar by J.H. Keys in 1921 and R.T. Bannister in 1934. Re-discovered by Roger Booth west of Seaton in 1999 and by Paul Gainey between Loe Bar and Gunwalloe Fishing Cove in 2008.

Habitat & Ecology

Found on wet shingle or sand at the base of seacliffs with wet seepages. Also known from exposed riverine sediments in other parts of Britain.

Threats

Disturbance of coastal shingle and sand systems, including gravel-winning as well as coastal and flood protection works.

Conservation

Much of the more sensitive coastline is now protected by SSSI designations. The Loe Bar coast is owned by The National Trust.
