About this species

Recorded altitude range
350m to 700m

Species text

The species has been recorded from Box Hill and White Downs, Surrey, and Stockbridge, Hampshire, all since 1962. It has also been reported from Spain, France, Romania and Slovakia.

Habitat and ecology
C. albidus occurs in beech litter in beech woods. Adult males have been found between August and November and females between August and April.

No records since before 1980, though the spider occurred in numbers at its Surrey sites. Area of occupancy very restricted. Recorded from three locations prior to 1992 but no records since.

The loss of established beech woods. In past years, foresters have clear-felled ancient beech woods on the North Downs and used a nurse crop of conifers in the replanting, a practice which could be detrimental to the ancient woodland fauna and flora, including this spider.

Management and conservation
Small group fellings with no conifer nurse crop should ameliorate the effects of previous management of the beech wood ecosystem. Survey work to establish the current status of this species is required.
