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.
Local in south-west Britain.
This species is almost certainly under-recorded in Cornwall, where prior to 2000 it has been found at Polperro and an unknown site in north Cornwall. Recent surveys on The Lizard have discovered this species at Beagles Point, Black Head and Chynhalls Cliff.
Habitat & Ecology
Recorded from quarries, cracks in cliffs and under stones in dry habitats. The Lizard
records are from maritime screes.
