The metal in Cicada ovipositors is so cool. The mechanics behind the iconic cicada sound is neat. The idea of bug sweat is interesting. Having so many predators is funny. The thanksgiving food compassion in predators having too many cicadas is silly. The prime number life cycles is neat. Anti-bacterial wings are so cool. The fungus making cicadas breed with anything, even males with other males, is both morbid and funny. Nick VanAcker was pretty fun.
