About this species

Recorded altitude range
1m to 240m

Species text

The spider has mainly been recorded in north-central England, with scattered records further south and in Wales. It is widespread in western Europe as far north as Sweden.

Habitat and ecology
L. dentichelis is generally found in damp and humid caves, mines and sewers and the filter beds of sewage works, but it has also been recorded amongst marram grass on sand-hills. The species has been studied by Bonnet (1932) who confirmed that humidity is the key factor in habitat selection. Females may be adult all year, males in the autumn, although our limited phenology data show adults of both sexes recorded in spring.

Local and uncommon.

The species may have been widely under-recorded because of its specialist habitat.

Management and conservation
No specific management recommendations can be made at present.
