Great song Chatty. I was thinking of "Rent" where the lovers are dying of aids and the opera "La Boheme" on which it is based where they are dying of tuberculosis.
I see the cicadas as lovers who have waited seventeen years to earn enough to begin the search for their lover.
They would be singing soulfully as they frantically search for their mates who they know they have only six weeks to find. Then if it's a real tragedy, they will die in each others arms before they can conumate their love. Or if it's a romantic comedy, they could die after finding each other and consumating their love.

Okay, it's a tragedy. Hey, these cidadas have a difficult and short life. A lot like an opera for sure.
