Sounds of Waterfall / Cicadidae

Order Homoptera

Every one who has wandered in a tropical forest must have been astonished at the din made by the male Cicadae. The female are mute; as the Grecian poet Xenarchus says, “Happy the Cicadas live, since they all have voiceless wives.” The noise thus made could be plainly heard on board the “Beagle,” when anchored at the quarter of a mile from the shore of Brazil; and Captain Hancock says it can be heard at the distance of a mile. The Greeks formerly kept, and the Chinese now keep these insects in cages for the sake of their song, so that it may be pleasing to the ears of some men. Thie Cicadidae usually sing during the day, whilst the Fulgoridae appear to be night songsters. The sound, according to Landois, is produced by the vibration of the lips of the spiracles, which are set into motion by the current of air emitted from the trachae; but this view has lately been disputed. Dr. Powell appears to have proved that it is produced by the vibration of a membrane, set into action by a special muscle. In the living insect, whilst stridulating, this membrane can be seen to vibrate; and in the dead insect the proper sound is heard, if the muscle, when dried and hardened is pulled with the point of a pin. In the female the whole complex muscle apparatus is present, but is much less developed than the male, and is then used for producing sound. ~ Page 291
