Wander anywhere in the Blue Mountains during the daytime and it's likely your ears will soon be ringing with the sound of countless cicadas singing for a mate | p_hannam

"The greengrocers are really out in force and there seems to be a real boom," Gerry Cassis, an entomologist at the University of NSW. "They're just like a freight train when they get together for a kumbaya."

A recently emerged greengrocer cicada - also known as a masked devil or yellow Monday - rests on a white Waratah flower near Mt Wilson in the Blue Mountains.That life cycle, which varies across the 246 described cicada species in Australia, does leave some varieties vulnerable to wildfires. Those males wisely close off other membranes, known as tympana, that serve as ears so they won't be deafened by their own song.

That still leaves at least 70 per cent – or perhaps 500 or more Australian cicada species – to be named, he said. Once they emerge, the final shedding of their skins marks their arrival as adults, ready to mate and to fly.
