Distribution
The species was known in Britain only from Burnham Beeches, Buckinghamshire. A doubtful report exists from Essex for the period 1935 - 45 (Hull 1947). In Europe the spider is widespread in southern and central areas.Habitat and ecology
Open woodland. The spider spins its web near the ground in areas of scattered bushes in open woodland and underneath hedgerows. In Britain, adult females were recorded in May.Status
The spider was found on several occasions early in the 20th century, when reasonable numbers were recorded. However, since 1950, there have been no records and this distinctive spider is probably now extinct in Britain.Threats
The vegetation where the spider was found at Burnham Beeches was mown to the ground in 1954 despite the SSSI designation of the site three years earlier.Management and conservation
Protect woodland or scrub where it occurs from clearance or damage. Text based on Dawson, I.K., Harvey, P.R., Merrett, P. & Russell-Smith, A.R. (in prep.).Stats
