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.

Tetrix ceperoi - Cepero's Ground-hopper



Range & Status

Nationally scarce and local. Predominantly coastal, from South Wales round to Essex. Also confirmed well inland from north Cambridgeshire. Not easy to separate from the Slender Ground-hopper Tetrix subulata , with which it may often be found, so may be overlooked.

Regional Distribution

Isolated colonies from Hayle to the Bude area on the north coast, and a large population on The Lizard. Small and elusive colonies have been recorded from Penwith, and a singleton was found at Portmellon in 1989.

Habitat & Ecology

Most records are from marshy localities on the Lizard plateau or from wet cliff face

seepages and cliff top marshes on killas cliffs, mostly on species-rich sites.

Threats

Trampling, or as at Constantine Bay arable cultivation.

00 Conservation

Some larger colonies are within nature reserves.
