Cicadidas are usually 1-2 inches in size. The females are distinguished from the males by having ovipositors which are visible on their bottom abdomen. Another distinction is the males are able to produce sound through organs located on the sides of their abdomen. Cicadidaes feed by sucking juices from tree roots and plant stems. After mating, the females lay eggs dozens at a time in small twigs. Some species of Cicadidas can live up to 17 years, however, most usually have a life span around 3 years.
