0m to 260m

Species text

The species is widespread, but scattered. It is widespread in north-western and central Europe.

Habitat and ecology
The spider occurs among low plants and on bushes in woods. Adults are found from May to July.

Although recorded from 16 counties, there are few recent records for this spider. It is possible that some of the old records from southern counties refer to X. acerbus Thorell, females of which are very similar to X. luctuosus. It has apparently declined precipitously in the past 20 years.

The loss of woodland to intensive forestry, and clearance of understorey.

Management and conservation
Maintain low plants and the shrub layer in woodland.
