In the insect world, their songs are considered the noisiest. Only the males of this family sing and it’s for the purpose of attracting a mate. Once that is complete, the female oviposits the eggs into a tree twig. When the nymphs hatch, they fall to the ground, burrowing into the soil in search of the tree roots. There they suck xylem sap for a number of years. When it’s time to become an adult, they crawl up the tree trunk and molt.
