Connecticut’s trees are coming alive with the sound of cicadas—billions of them. After 17 years underground, Brood 14 cicadas are emerging, but this time, many are infected by a fungus that turns them into “zombies.” The fungus hijacks the cicadas’ reproductive systems, causing them to act erratically and spread spores to others. This phenomenon is expected to impact trees across the state. Though harmless to humans, the cicadas could harm young trees with their egg-laying habits.
