But some Australians have been quick to point out the noticeable absence of one of our most iconic sounds, and experts say they are not alone.
Cicadas have been clearly missed from the summer until now in 2021, but fortunately their disappearance is due to a natural process that enthusiasts say is completely normal.
“Last year there were a lot more cicadas,” said cicada expert Dr. Lindsay Popple.
“Several species were synchronized last year and came out together in numbers, so by extension you are bound to have a quieter season after that.”
Dr. Popple said the summer after a major outbreak of cicadas is usually less significant because the next generation spends a number of years underground before reappearing.
“Another factor is that a lot of eastern Australia has had higher-than-average winter rainfall, and it produces conditions ripe for natural enemies of cicadas,” he added.
Most people are not aware that cicadas actually spend most of their lives underground, and they only get above ground when it’s time to mate.
“So it’s just the last part of their life cycle that they show up and start making all that noise.

“Once they appear as adults – it depends on the weather and conditions – but they can be above ground for only one or two weeks, especially the smaller ones.”
Dr. Popple said it may even take a few more years before we see a mass resurgence of the creatures again.
“I reckon that around 2023 or 2024, it will probably (not) be until then, we get the big boom,” he said.
