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.

A pair were collected by G.H. Ashe in ' Cornwall' (Allen, 1994).
Habitat & Ecology
The Devon record is for a male found beneath bark on deadwood in an old pasture-woodland on the south-west flanks of Dartmoor.
Threats
Agricultural improvements and commercial forestry around moorland fringes, especially where they interrupt the moorland/woodland transition.
Conservation
Protection of remaining moorland of Bodmin Moor and its woodland fringes from
inappropriate developments.
