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.
Range & Status
This bug is, in Britain, confined to the Isles of Scilly, Sennen Cove and Kent. It was formerly mistaken for Emblethis verbasci (Fabricius) (S. Judd, pers. comm.).
It is well-established in the Isles of Scilly, where populations are probably stable: it is known on St. Mary' s, Tresco, Samson, St. Agnes, St. Martin' s, Bryher and Tean. It appears to have always been scarce at Sennen Cove and there is no evidence of decline; it is still readily to be found here.
Habitat & Ecology
This species prefers a mosaic of low vegetation and bare ground in sand dunes and other sandy habitats near the coast. It occurs both in the fore dunes and behind, associated with Marram Ammophila arenaria , Common Stork' s-bill Erodium cicutarium , Spurges Euphorbia spp. and sparse grassland. The bugs are seed feeders.
Recreational pressures leading to the erosion of dune vegetation.
Visitor pressure should be managed to ensure pressure is uneven.
