cicadas is during their egg-laying process. The female chisels gashes in tree twigs with her long, spearlike ovipositor and deposits her 400-600 eggs in the slits. Such gashing often causes the twigs to wither.
The cicada is hard on human eardrums^ So great is the din of a cicada ‘chorus that schools have had to'close because pupils could not concentrate on studies in such an uproar. One of the several cicada “tunes” sounds like a big knife being held against a coarse, whirling grindstone. Another, which gave colonists added fear of a Bibical plague, seems to intone the name of Egypt’s ruler, Pharaoh.
The cicada sings with his stomach. Two abdominal drumheads of membrane are vibrated by powerful muscles to make the unnerving, dismal * “song.” Only the males sing, inspiring the ancient Greek, Xenarchus, to quip: “Happy are cicadas’ lives, for they all have silent wives.”
