Priocnemis perturbator is a relatively large species of spider wasp which is quite common in Europe.

As stated in the introduction, many of the observations of P. perturbator collecting prey refer to the invalid taxon P. fuscus, but this species is thought to take larger spiders of the families Lycosidae and Gnaphosidae.

[3] This species is one of a handful of relatively large spider wasps, including Priocnemis susterai and Anoplius viaticus which overwinter as adults in Britain, emerging in the following spring.

Priocnemis perturbator, which is reasonably common and has long antennae, can often be seen nectaring on wood spurge,[4] dandelion, blackthorn, hawthorn and willow.

[3] P. perturbator is widespread, from Great Britain and Ireland into central and northern Europe and Asia eastwards to Japan.
