Recorded altitude range3m to 170m
Species text
DistributionThe species is widely scattered in England and Wales. It is widespread but local in northern and central Europe.
Habitat and ecology
The spider occurs among Molinia and Sphagnum in lowland bogs, and among low vegetation in marshes and fens. Adults of both sexes are found in October and November, and from March to July, and probably over-winter.
Status
UK Biodiversity Action Plan priority species. The spider is frequent at some sites, but very local and has apparently undergone major decline in the past 30 years. Trend analysis of the continuing decline in area of occupancy over the period 1976 to 2005 indicates a reduction in population size of 32% over a ten year period.
Threats
Drainage of bogs and fens. Acid bog and fen habitats are also under threat from succession and climate change.
Management and conservation
Maintain the water table of bogs and fens.
