Species text

The species is widespread but scattered as far north as the Scottish border. It seems to be concentrated in the central and south eastern parts of England. The species is widespread but uncommon in northern and central Europe.

Habitat and ecology
S. gracilis occurs mainly in calcareous and grazing marsh grassland possibly mostly in tall grass, but also grassland on sand (Thames Terrace grasslands) with occasional records from grassy areas on heathland, dyke edges and allotments. Adults have been found between February and November, but occur mostly in spring and early summer and again in late summer and autumn.

The spider is very local and never particularly common. It has been recorded from only fifteen 10 km squares since 1992, but in general is not as rare as was once thought.

The loss of grassland to agriculture.

Management and conservation
Maintain calcareous grassland and grazing marsh and prevent scrub growth by traditional grazing.
