Chorus cicada have a nymph stage before their last molt and become an adult.
During this nymph stage they are a soft and creamy white, and very similar looking to the adult form (but without wings).
The lengths of the adults are usually larger than 2 cm in length  while the largest species are up to 4 cm; this includes the wings.
Chorus cicadas’ wings only appear after molting to become adults, they are membranous with veins and they filter out ultraviolet light and the wing span is about 6 cm.

The colour of the chorus cicada can be black/green/brown and many have stripes along their body.
The antenna of the chorus cicada has seven segments with the seventh being constricted medially  which means the last segment is tightened towards the middle.
The adult male cicadas differ to the females by the presence of a clasper sheath, and females don't have finger like extensions that the males have.

The song made by cicadas is the loudest noise made by an insect.
The male chorus cicada produces a communication song that is specific to their species, and so species can be identified by their song.
A pulse group of their song is made up of five clicks where the central click (third click) is stronger than the two on either side of it.
The central click can become two clicks if the cicada is tired and has no energy.
These clicks are made by the cicada hitting its wings against the surface it's sitting on.
These pulse groups can be produced quickly and continuously in a prolonged note during chorus sing.
It is New Zealand's biggest cicada, their size is averaging around 40 mm.
