Ceropales maculata is a kleptoparasitic spider wasp found in the holoarctic region.

C. maculata then allows the other spider wasp to return to its nest, where the C. maculata larvae hatch, eat the host egg, and consume the spider.

[5][6] Spider wasps kleptoparasitised by C. maculata include species in the genera Priocnemis, Pompilus, Agenioideus, Arachnospila, Anoplius, Episyron and Auplopus in Britain and Europe.

Other species of non-Pompilid solitary wasp which use spiders as prey, for example the crabronid Miscophus, may also be parasitised by C. maculata.

[2] C. maculata can be found in sandy areas such as heathlands, coastal dunes and sand pits.
