About this speciesRecorded altitude range
0m to 700m
The species is widespread in the southern half of Britain with few records in the south-west, Wales or northwards from Yorkshire to central Scotland. It is widespread in western and central Europe, but has not been recorded from Ireland.
Habitat and ecology
The species occurs mainly on heathland and calcareous grassland, perhaps preferring habitats with sparse vegetation. The orb webs of this spider lack the silken retreat and signal line typical of the family Araneidae. They are constructed in vegetation near to ground level and any disturbance may cause the spider to drop into the litter layer. Males are adult from spring to autumn. Adult females may be present all year.
The species shows an apparent decline, so a Watching Brief should be kept on this species. Generally uncommon.
Loss of heathland and calcareous grassland to agriculture and urban development are likely to the most important threats to this species.
Management and conservation
Prevent further loss of heathland and calcareous grassland in areas where it occurs.
