Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Hemiptera
Suborder: Auchenorrhyncha
Infraorder: Cicadomorpha
Superfamily: Cicadoidea
Family: Cicadidae
Genus: Amphipsalta
Species: Amphipsalta zealandica
Common name: Chorus cicada,

Only males make the chorus. The adult male cicada possesses two ribbed membranes called tymbals, one on each side of its first abdominal segment. By contracting the tymbal muscle, the cicada buckles the membrane inward, producing a loud click. As the membrane snaps back, it clicks again. The two tymbals click alternately.
Air sacs in the hollow abdominal cavity amplify the clicking sounds. The vibration travels through the body to the tympani, which amplify the sound further.
Chorus cicadas are found all over the North Island.They are also found in coastal areas of the South Island except for Dunedin north to about Timaru and Stewart Island.
