Other Clubiona species. 

Confirmation of this species requires examination of the genitals of mature specimens.

Microscopic examination of the genitalia is necessary to confirm identification.

Typically found on trees and shrubs, on bark or by beating. An unusually high proportion of records are from gardens, both urban and suburban. It also occurs under stones, inside houses, outhouses and derelict buildings and in grassland. Overwinters under bark or in leaf litter.

Adults of both sexes are found mainly in late spring and summer, females occasionally until December.

Local, but more common in the south of Britain.

Widespread but under recorded.
