About this speciesRecorded altitude range
3m to 900m
Widespread in southern Britain but becoming very scattered in the north. A Palaearctic species widespread in north-western and central Europe. It has not been recorded from Ireland.
Habitat and ecology
The spider occurs in moss and grass, usually in broad-leaved woodland. Males probably occur from late autumn through the winter and spring.
Uncommon and evidence suggests significant decline.
In the past, conversion of ancient woodland to intensive forestry represented a threat. It is also possible that the ending of coppicing in traditionally managed broadleaf woodlands may have affected this species although too little is known of its ecology and micro-habitat requirements to be sure what threats it faces.
Management and conservation
Conversion of broadleaf woodland to conifer plantations should be avoided and traditional coppice rotations maintained where possible. Until more information on its ecological requirements becomes available, precise management recommendations cannot be formulated.
