About this speciesRecorded altitude range
1m to 200m
Apart from old (doubtful?) records from Aberdeenshire, the species is confined to south-central and south-eastern England. It is widespread but uncommon in north-western and central Europe. It has not been recorded from Ireland.
Habitat and ecology
C. incilium occurs mainly on chalk grassland and on sandy grassland in Essex and Breckland, in both long and short grass, occasionally on arable land. It has occurred on roadside verges and in old chalk and sand pits especially on sparsely vegetated ground and lichen heath. Both sexes are adult from autumn to late spring with a peak in winter, females also until June.
Although recorded from 16 hectads since 1992, only twelve of these are where spiders were recorded both before and after this date. It shows a moderate decline, hence the Watching Brief.
The loss of grassland to agriculture or forestry.
Management and conservation
Maintain grassland by traditional grazing or periodic scraping to return to early succession.
