[["Cicadas are animals so they come from other cicadas. The mother deposits eggs which hatch into larvae. They look like small ants or termites at this stage. When mature enough, they burrow into the ground and feed on tree roots for 2 to 17 years, at which time they emerge to start the cycle all over.", 63.0], ["There are perhaps 3,000 to 4,000 species of cicadas around the world, but the 13- and 17-year periodical cicadas are unique to eastern North America. After 17 years underground, sucking sap from tree roots, the cicadas will surface en masse.", 14.0], ["The earliest known fossil Cicadomorpha appeared in the Upper Permian period; extant species occur all around the world in temperate to tropical climates. They typically live in trees, feeding on watery sap from xylem tissue, and laying their eggs in a slit in the bark. Most cicadas are cryptic.", 13.0]]
