About this species

Recorded altitude range
-4m to 650m

Species text

The species is widespread throughout most of Britain. It is widespread in western and central Europe.

Habitat and ecology
This spider spins its orb webs on grasses and other low vegetation especially in waterside and wetland habitats, both lowland and upland. As with other members of this genus, when disturbed the spider leaves its web and stretches out along a leaf with the four anterior legs pointing forwards and the four posterior legs pointing backwards. Its elongate shape, combined with this pose, enables the spider to escape detection by predators. Both sexes are mature from early to mid-summer and sometimes into the autumn.
