Cicada, what a noise!

The cicadas are out in full force this summer. A week ago, while walking in the bush on a hot morning, I was suddenly doused in spray of cool drops from the trees above. It seems cicadas do pee. Copiously. A quick check of the internet assured me the spray is harmless. You can basically view it as sugar water that’s passed through a cicada.

However, the occasional dousing is not the most noticeable characteristic of cicadas. The thing most people notice about them is their singing. Song is not exactly the right word. What a noise! Only the male cicadas sing. This video shows how they pulsate their abdomens to make the noise:

They are large insects, about the thickness of an adult person’s thumb, and interesting to look at. I think they’re quite attractive, in an outdoorsy sort of way:

They have an impressive life cycle. The adult cicada is the winged insect we see, and it lives for only a few weeks. But the nymphs, which are the form of the creature that hatch from the eggs, live for around seven years, underground. A previous post of mine has pictures of the empty husks left behind when a nymph transforms into the winged adult.

This picture shows the underside of one cicada as well as the top of another:

I think these are Black Prince cicadas (Psaltoda plaga). I found them at Manly Dam National Reserve, near Sydney: 33°46’37.6″S 151°15’09.4″E.

The cicadas in my previous post were Floury Bakers (Aleeta curvicosta), noted for singing upside down.

This blog is primarily about birds, and cicadas aren’t birds. But they’re nearly as big as some birds, and they’re part of our local birds’ ecosystem. In fact, the larger birds have a feast during cicada season. One of my first memories of Australia is of coming across half a cicada buzzing aimlessly on a path through a bushy area. The insect was bright green, the first green one I’d ever seen, and the sight filled me with sadness. So I’m happy to see them when they come, even though their call is a little intrusive!

  1. Hi Sarah, cicadas go hand in hand with summer, and it’s deafening up here in Qld too! 🙂
