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.

Odontoscelis lineola

Range & Status

Confined in Britain to southern coasts, including Cornwall.

Regional Distribution

Found on most of the major dune systems along the north coast: Gwithian, Penhale,

Holywell, Constantine Bay, Harbour Cove (Padstow) and Rock.

Habitat & Ecology

A coastal sand dune species associated with Common Stork' s-bill Erodium cicutarium and probably also Sea Stork' s-bill E. maritimum . Nymphs hibernate in moss or buried in sand near the host plants. Stork' s-bill growing in fairly firm and stable sand appears to be preferred, often with a sparse growth of moss. The bugs burrow into sand in cold weather or in response to disturbance.


Rabbit grazing and digging have been very beneficial at many sites, but reduction in

numbers of rabbits following myxomatosis may have had a serious effect on the bugs. Stock grazing may also be important. Visitor trampling may be a problem.
