I follow a narrow variety of people on Twitter, focusing on insect experts and enthusiasts, and specifically, many people who focus on cicadas. Too see all the folks I follow, Visit my Twitter account.
Only a percentage of their posts are about cicadas, but they are still the best bets for cicada news on Twitter.
