‘The common, maternally-inherited endosymbiont, Cardinium heritigii, resides in the reproductive organs of the minute parasitoid wasp, Encarsia inaron. Cardinium manipulates wasp reproduction by fatally sabotaging sperm inside host testes (pictured here) so that female wasps require the symbiont to successfully reproduce’, copyright [Matthew R.
