We spent Memorial Day weekend in Southern Illinois, and these cicadas greeted us. My cousin told me that these are 13 year periodic cicadas. Further investigation found an article from Scientific American that also calls them the "Great Southern Brood" or brood XIX. The article notes that you can eat them and compares them to asparagus. My cousin's husband as well as my husband described them as buttery and creamy. No thanks....I'll pass...
