what is it?
Porcellionides pruinosus is a cosmopolitan woodlouse that is native to Europe, and is suspected to consist of very closely related species. Ten subspecies are recognised. The species carries Wolbachia endosymbionts, which is an alpha-proteobacterium that is known to modify the reproduction of their crustacean hosts by inducing cytoplasmic incompatibility or feminisation.
