Status (in Britain only)
This species is not regarded as being scarce or threatened.
June to August; occasionally as early as late May.
Prey consists of small jumping spiders of the family Salticidae, with the occasional collection of members of the Thomisidae (Day, 1988). The wasp also hunts spiders which live in vertical, or near vertical faces, such as cliff walls and upturned root-plates. It is normally found away from such situations (M Edwards, pers. comm.).
