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.

Dromius quadrisignatus - A ground beetle



Range & Status

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

Regional Distribution

Known from two old records: Porthgwarra (R.T. Bannister, 1963) and Marazion (1906).

Habitat & Ecology

The rarest of the four-spotted arboreal Dromius species; like the others, it is found on

the trunk and branches of broadleaved trees and shrubs, and its rarity inexplicable at

present.

Threats

The reasons for its extreme rarity are not understood and so it is impossible to suggest threats.

Conservation

The reasons for its extreme rarity are not understood and so it is impossible to formulate a conservation plan.
