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.

Ponera coarctata - The Indolent Ant

Range & Status

Local across the southern counties of England.

Regional Distribution

Recorded since 1980 from the southern tip of The Lizard and from Kynance Cove and more recently from Pentire Point in 2006. Previously recorded from the Rame Peninsula, where it may still occur. This ant is very small and easily overlooked, looking rather like a rove beetle.

Habitat & Ecology

Found on sea cliffs and cliff faces, making small nests under stones, preferring warm sites. Often associated with the nests of other ants e.g. Lasius flavus .


Occurs on steep unstable cliffs, where nest sites are vulnerable to disturbance.
