Mating is triggered by the song of the males which facilitates the gathering of many males and females.
Males compete with each other to produce the loudest and best musical sound, and sing louder when the weather is warmer.
Sometimes two cicadas will fight each other.
Chorus cicadas usually mate on a tree trunk silently.
 Adult cicada have a short life span of only two to three weeks, because after mating the adult cicada die off.
Female chorus cicadas lay their eggs into thin branches of a wide range of plants.
 Females lay from 5 to 700 eggs, each about the size of a grain of rice.
 They lay eggs in a herring-bone pattern in the thin tree branches.

The eggs take 3 to 10 months to develop and hatch.
Hatching occurs from May to mid-December.
After hatching the larvae burrow into the ground where they grow and develop their organs and increase in size.
This process and the transformation into nymphs occurs during the springs and winter months.
During this period the nymphs feed on the juices of roots and other underground organisms.
The nymph stage of the cicada can last from 25 to 44 months.

Once the nymphs have grown to their maximum size they emerge from the ground and climb up tree trunks to molt.
This is the transformation that turns the nymphs to adult cicada.
This occurs on summer nights during the period of mid-December to late February.
Once out of their last nymph skin their wings expand and they wait for them to harden before they can fly off.
