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.

Ceutorhynchus atomus - A weevil

Range & Status

Formerly widespread in Britain and may have become scarcer; more-or-less confined to the south.

Regional Distribution

Old records from Tregantle Down, Whitsand Bay (Walker, 1875) and Gwithian in 1936 by R.T. Bannister.

Habitat & Ecology

Feeds on Thale Cress Arabidopsis thaliana and occasionally Shepherd' s Cress Teesdalia nudicaulis and other Cruciferae on coastal shingle, saltmarsh and waste ground.


As the foodplant is ruderal, disturbance must be the key to its conservation.
