Distribution
Most records are from Dorset and the New Forest, East Anglia and the coast between West Norfolk and North Lincolnshire. The species is scattered but uncommon in Europe. It has been recorded from most countries in north-western Europe, but is included in the Red List for Sweden (Gärdenfors 2000) and has not been recorded from Norway.Habitat and ecology
This species has been recorded from damp heaths and fens. It occurs in damp situations at ground level and in grassy tussocks. It has also been collected on shingle and amongst marram on dunes. Adults of both sexes have been recorded in May and June, females until October.Status
Recorded from 16 hectads since 1992, but showing an apparent decline of about 50% in hectads with spider records both before and after that date (from 23 to 11), though lowland heathland and East Anglian fens are both known to be very under-recorded recently, so we prefer to treat this as Scarce rather than threatened.Threats
The loss of heathlands to agriculture and forestry; the drainage of fens.Management and conservation
Maintain the damp nature of these habitats. Text based on Dawson, I.K., Harvey, P.R., Merrett, P. & Russell-Smith, A.R. (in prep.).Stats
