What is the song of the cicada?

Who wrote a cicada song?
People might be talking about the cicadas, but in Pikesville, some fourth graders are singing about them. “It’s a cicada,” is the title of the No. 1 hit song going around the Krieger Schechter Day School in Pikesville, where music teacher Sara Fuld dusted off a song she wrote 17 years ago for a whole new brood to sing.

As trees go through their seasonal cycles, shedding and growing leaves, the composition of their sap changes. And when cicada nymphs feed on that sap, they likely pick up clues about the passage of time. The 17th iteration of the trees’ seasonal cycle gives the nymphs their final cue: it’s time to emerge.
