Xenos vesparum is an insect species, whose females are permanent entomophagous endoparasites of Polistes paper wasps. They dwell their whole life in the abdomen of the wasp. One particular species of social wasp it has been known to infect Polistes gallicus. The younger members within the colony tend to be the targets, although this insect display parasitic behavior in all stages of this host.
According to Fabio Manfredini of Pennsylvania State University, co-author of an Animal Behaviour study of this insect's odd life cycle, published on 8 October 2011, the parasite infects a European worker wasp and completely alters its worker caste behaviour. The infected wasp begins to suffer nutritionally, then flies to meet with other infected wasps. The male parasite exits the wasps abdomen and mates with the female parasites which stay inside their host. Wasps infected with the male parasite die. Wasps infected with the female parasite then fatten themselves up much like queen wasps do. They then fly to meet with other uninfected queen wasps. Then when the parasite is mature, the infected wasp flies to mingle with other uninfected wasps, thereby spreading brood and larvae into new environments.
