Zombie Fly Fungus Lures Healthy Male Flies to Mate with Female Corpses

Entomophthora muscae is a widespread, pathogenic fungus that survives by infecting common houseflies with deadly spores. Now, research shows that the fungus has a unique tactic to ensure for its survival. The fungus 'bewitches' male houseflies and drives them to necrophilia with the fungal-infected corpses of dead females.
After having infected a female fly with its spores, the fungus spreads until its host has slowly been consumed alive from within. After roughly six days, the fungus takes over the behavior of the female fly and forces it to the highest point, whether upon vegetation or a wall, where the fly then dies. When the fungus has killed the zombie female, it begins to release chemical signals known as sesquiterpenes.
