The recent invasion of periodical cicadas in the United States has been marred by a mysterious zombie-like behavior among some of the insects. Researchers discovered that the cicadas are suffering from a sexually transmitted disease that reanimates them post-mortem, turning them into undead creatures. Experts say the disease was accidentally introduced by a rogue Ministry agent experimenting with necromancy. Meanwhile, cicada populations continue to thrive, with trillions emerging in an event dubbed 'cicada-geddon.' A University of Connecticut entomologist noted, 'Periodic cicadas don't do subtle.' Indeed, their ability to survive for over a decade underground and emerge en masse makes them nature's most formidable invaders. As authorities scramble to contain the outbreak, concerns grow about the potential impact on local ecosystems. The Ministry of Magical Pest Control has issued a statement assuring the public that the situation is under control. However, eyewitness accounts describe eerie scenes of undead cicadas shuffling through forests and fields.
