Chorus cicada

Māori name: kihikihi wawa, matua kihikihi, ngengeti

English name: chorus cicada

Scientific name: Amphipsalta zealandica (Boisduval)
order = Hemiptera; family = Cicadidae

is found throughout most of Aotearoa / New Zealand;
typically lives in tall forest (or where tall forest used to be);
males "sing" in unison;
when numerous males sing together they can produce a deafening, strident uproar, which suddenly changes to synchronised "clicks" as the wings are clapped against the tree trunk;
females lay eggs in herringbone-patterned slots in branches;
nymphs hatch out the following spring and drop down to the ground;
nymphs spend several years underground, sucking sap from tree roots;
a nymph emerges from a wide burrow when ready to become an adult, climbs a tree trunk, and splits its skin down the back. The adult pulls itself out, expands its wings, and flies off.
