And now a bit of Cicada Data...from the National Science Foundation.
Announcer: Single female cicada, 17, red eyes, in search of mate for whirlwind romance and more. Must be able to woo me with his love
song. Respond quickly--only five weeks to live.
(SOUND: male mating call)
Announcer: The serenade of the male cicada--perhaps the loudest sound produced by any insect.
Odland: It takes a lot of energy to make all that noise. The animal really has to warm up.
Announcer: That's Indiana University researcher John Odland. He says to sing, male cicadas need to reach a body temperature of
about 95 degrees.
Odland: A few males start singing, they set up what's known as a "calling center," and it's likely that other males join that calling center to increase the amount of noise, rather than call individually, when someone else has already started. So, they concentrate partly to make more noise and attract more females--same theory as a heavy metal band.
Announcer: That's Cicada Data. I'm Emilie de Azavedo.
