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.
Range & Status
Confined to a few sites, mainly along the southern coast of England (Devon, Dorset, Isle of Wight, Sussex and Kent, as well as Essex and Somerset), as well as Cornwall. It may be under-recorded because of its subterranean habitat (Falk, 1991).
Status in Cornwall currently unknown; last recorded here before 1950 on the southern tip of The Lizard.
Habitat & Ecology
Generally coastal, where it is found where cliff falls provide bare ground. Usually associated with Lasius and Formica ant nests, preying upon their brood.
Survey work is necessary to establish whether it still survives in west Cornwall, where it may be present in suitable habitat where nests of larger ants occur.
