2. Cicada Facts Cicadas live mainly in warm-temperate to tropical habitats.
There are about 1600 species of Cicada in the world and around 200 species live in Australia.
Cicadas have life cycles that last from one to several years.
The common names for cicadas vary widely around the world. In Australia, children were the first to coin the common name for many cicadas: Black Prince, Green Grocer, Double Drummer, Tiger, Brown Prince, Cherry Nose, Floury Baker, Red Eye, Hairy Cicada, Bladder Cicada, etc.
Although abundant, cicadas are far more often heard than seen. Only male cicadas sing. They do this in an attempt to find a mate.

Stage 3 , adult
5. Stage 1: Egg After mating , the female lays several eggs. She makes a little slit in the bark of a tree branch as she walks along and pushes the eggs down through her long tail. She deposits about 12 eggs into each slit and moves on a few millimetres to make another slit for more eggs , and so on , until she lays up to 400 eggs. The eggs stay in the slits in the bark for 6 to 10 weeks and then hatch into a miniature cicada called a nymph.

7. Stage 2: Nymph The nymphs fall down from the tree to the ground without getting injured because they are small. They look for shelter underneath the leaf litter. They search for cracks and burrow down between 10cm and 40cm. It is underground, that cicadas spend most of their life. The cicada nymphs feed by piercing small tree roots with their needle-like rostrum and sucking up sap. When sap runs out, they tunnels around to find a new root to feed from.

9. Stage 3: Adult After anywhere between 1 and 17 years the nymph digs its way to the surface, climbs on to a tree trunk and sheds its skin for the last time leaving a telltale brown shell. The life of the adult, in contrast to that of the nymph, is very short. After becoming an adult the cicada only lives for another 5 to 6 weeks.

11. Why the cycle is important In the nymph stage it is quite safe living underground because it might get eaten by birds and lizards. The nymph wonít be able to eat anything because it needs to eat tree roots underground. When they turn into adults theyíll need to have wings to find a partner to mate with so they can have babies and the cycle will go all over again.
