I have tinitus. Cicadas all year round for me!

It's the light that sets them off. They're a go at dawn and shut down after twilight. They're driving me crazy here too, we get a lot of them where I live but this year has been especially noisy. Hopefully the southerly front will slow them down for a day or two.

They start well before dawn here.
We have had them bad for months here, Although they have been no where near as bad thr last few weeks as its colled down a little.
My parents have Kiwifruit they love those.
Its only seem to be certain trees they congregate at.
Likely a little Bug spray on the trees would fix the issues up.

Why do they like kiwifruit? They dont eat. Just breed and die,

Wifey tells me ours are 7 year cycle .

No idea, but they love the patch their, Always have, maybe they breed the same place year in year out, i have no idea.
But when i go on a walk past the golf course its the exact same trees every time they are in in the native reserve as well (not kiwifruit there clearly)
We have the whistling frogs at night as well.
I am sraying the Silver birch trees at my place that they were all in here next year just to see what happens.
I google ihow loud they were it said up to 120Db and they bloody sound it.

Wifey has just gone whistling tree frog crazy but they are pretty quiet

There are a little small for stir Fry.
I dont mind them, they are real hard to find if you shine a torch at them they stand still and stop whistling

[BMWST?]

I thought NZ circadas were 13 or 17 year cycles but I have no idea why I thought that. They are usually prime number years though as it lessens their probability of meeting up with their predators, whatever they might be.

Crickets make sound by rubbing their wings together (not its legs!), and cicadas have a special organ called a tymbal that produces sound. The tymbal contains a series of ribs that buckle one after the other when the cicada flexes its muscles. Every time a rib buckles, the rib produces a click.[3] Many clicks produce a buzzing sound. The action is like how a bendy straw makes sound: pulling and pushing the ribs of the bendy straw together makes a series of clicks. If you could push, pull, and twist a bendy straw hundreds of times a second the sound of the clicks would be so close together that you'd only hear a buzzing sound: this is how fast the cicada is able to vibrate its tymbal.

I think they live underground for most of their life as lavae.
What i jut read seems to agree with your 17 years. but its species dependent 2-17 years.
It seems they live in grow up an dine as lavea on certain trees, this might explain there always seeming to be in one place year after year.

Ha ha. Me too. Thanks to having a noisy helmet for a few years. Use ear plugs now but too late.

Stayed at Picton Top Ten camping ground two years ago and the cicadas were phenomenal. In the photo, each bump on the power line is a cicada. One managed to get into our unit and stayed hidden until 1am when it started doing it's thing. I don't mind bugs at all but when I went out for a pee at 2am, the toilet door in the ablutions blocked was covered in cicadas ... probably up to 100. I didn't fancy disturbing them and having them swarm me so finished up behind a tree instead.
