Cicadas infected by 'zombie' fungus

SOURCE www.npr.org
Cicadas from brood XIX are being infected by a fungus that turns them into 'sex-crazed zombies' by tearing off their genitals but driving them to keep mating. The fungus replaces the cicada's backend with a 'chalky white gum drop' and keeps them alive to spread spores. Infected cicadas become hypersexual and even pretend to be females to mate with other males. The fungus also produces a stimulant that possibly makes the cicadas 'high out of their minds.' The infection doesn't pose a risk to humans.

Key Points

  • The fungus Massospora cicadina infects cicadas from brood XIX and brood XIII.
  • Infected cicadas become hypersexual and engage in futile mating attempts, spreading the fungus.
  • The fungus produces a stimulant that may make the cicadas feel high.
  • The infection is not harmful to humans or other animals.

Pros

  • The fungus helps spread its spores by keeping the cicadas alive and hypersexual.
  • The infected cicadas are not harmful to humans.

Cons

  • The fungus causes harm to the cicadas by replacing their body parts and manipulating their behavior.
