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.

Lebia cruxminor - A ground beetle

Range & Status

Always very localised in England, but has been very much scarcer in recent years.

Regional Distribution

A speciality of Bodmin Moor: discovered at Treneglos (Wollaston, 1844) and re-discovered on the Moor by K.C. Side in 1972. It is said to have been found more recently, during the 1980s, but the details are not available (Luff, 1998).

Habitat & Ecology

Larvae are parasitic on the leaf beetle Galeruca tanaceti and perhaps other leaf beetles, and found in two very different types of situation - fen meadow or chalk downland.


Agricultural intensification, including drainage works; abandonment or tree planting of rough pastures.


Protection from agricultural improvement and development of remaining wild areas of Bodmin Moor.
