Arachnospila anceps

This species is found in northern and central Europe, including most of Britain and Ireland, and in Asia east to Mongolia.^[2]

The flight period is May to September and the species is probably univoltine. A wide range of spiders are taken as prey; the families Lycosidae, Clubionidae and Thomisidae have been recorded and Gnaphosidae and Agelenidae are also possible prey.^[2] The spider is paralysed before being dragged backwards^[3] to the nest site where it is hidden on a plant while the burrow is rapidly excavated. It occurs in a variety of habitats and on most soils with the possible exception of heavy clay soils.^[2] There are no records of which flowers are visited by A. anceps for nectar.^[2]
