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
A scattered distribution across the English lowlands. It has been recently recorded from Gloucester and Devon as well as Cornwall (K. Alexander pers. comm.).
Recorded from one 10km square, from beneath bark on an ancient Beech Fagus sylvatica tree in Boconnoc Park (Alexander, 1993a).
Habitat & Ecology
They are primarily associated with old open-grown trees where they feed on a wide variety of invertebrates beneath loose bark and in decaying wood, but that they are occasionally also reported from compost heaps, perhaps taken there phoretically by Diptera?
The removal of old trees from woodlands and parks.
The maintenance of ancient trees.
