Cicada

I saw a cicada nymph this week. I don't remember anyone talking about eating them 17 years ago, though the paper this year has a 1902 recipe for cicada and rhubarb pie. The rhubarb is up in time.
Soon enough the air will be full of large buzzing insects. They'll fly around in a mating 'dance', making their own 'music', a small dense population like a city that convenes every 17 years.
