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.

Strongylocoris luridus - Sheep's-bit plant bug

Range & Status

It occurs over much of Europe, but is absent from the extreme north. In Britain it occurs mainly in the south-west.

Regional Distribution

It is rather common on Sheep' s-bit Jasione montana on walls in the Isles of Scilly and is quite frequent in suitable places across Cornwall (Kirby, 1992).

Habitat & Ecology

It feeds on Sheep' s-bit Jasione montana growing in open structured swards, where there is much bare ground or rock, and usually south-facing. On cliffs, and other rocky places, including old walls.


Recreational pressure may cause local erosion leading to diminution of the area of habitat available. A more serious threat is the reduction in grazing leading to coarsening of vegetation and scrub development.
