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.

Rhyparochromus pini - A ground bug

Range & Status

A widespread species in Europe but of southern distribution in Britain. It appears to occur at low density and so may be overlooked to some extent.

Regional Distribution

Widely reported around the coasts of West Penwith and The Lizard; also along the north coast.

Habitat & Ecology

Chiefly a coastal species in the south-west, occurring on sand dunes and sparsely vegetated slopes on and behind cliffs. A seed-feeder; an association with Common

Stork' s-bill Erodium cicutarium has been suggested, but the evidence is weak. Adults hibernate amongst leaf-litter and in deadwood.


Heavy public pressure may cause damage through erosion; developments for recreation may cause problems.


Re-establishment of cliff grazing may be of value. Periodic scrub clearance would be

00 beneficial.
