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.

Forficula lesnei - Lesne's Earwig



Range & Status

Nationally widespread but local; currently recorded from 38 10km squares across southern England and on Gower Peninsula.

Regional Distribution

Rediscovered in the Isles of Scilly by Chris Timmins in late September 1993, after a 100 year gap since C.W. Dale first recorded it there in October 1890. Subsequently it has been found on most islands. On mainland Cornwall, Chris Timmins had the first modern record at Marazion, also in 1993. In VC1, it has subsequently been found in a handful of locations in the far west of Cornwall, and on The Lizard. In VC2, the only recent record is on Rock Dunes, alongside the Camel Estuary in 2003.

Habitat & Ecology

In Cornwall and in Devon, it has only been found in coastal herbage, but elsewhere it has been found well away from the coast, especially on basic soils. Most records come from a late summer/early autumn search of the dry stems of Hogweed Heracleum sphondylium , where they overwinter.

Threats

Conservation
