Arachnospila anceps is one of the more common spider wasps of western Europe.

A. anceps is a medium-sized, black and red spider wasp.

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

[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.

[2] There are no records of which flowers are visited by A. anceps for nectar.
