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.

Ochthebius poweri - A water beetle



Range & Status

A south-western coastal species recorded from Cornwall, Devon, Dorset and

Pembrokeshire. Foster (1990) provides a national distribution map.

Regional Distribution

Recorded from The Lizard in 1921 by J.H. Keys and Whitsand Bay in 1912 by T.J.

Willcocks. This is a difficult species to locate, and although there are no modern records for Cornwall, it may still survive at suitable localities around the Cornish coast.

Habitat & Ecology

Restricted to small seepages and trickles on and at the base of coastal cliffs, most

commonly on sandstone substrates.

Threats

Pollution of water courses, perhaps through agricultural run off or tourist developments. Sea defence schemes or stabilisation of cliffs.

Conservation

Some sections of the Whitsand Bay cliffs are under the ownership of The National Trust and most of the Lizard cliffs are SSSI. This species is listed on the UK BAP Priority Species list (2007).
