With the warm – well, actually hot! – weather at this time of year, our local bushland is fairly fizzing with the sound of cicadas.
We have several species locally, and I wrote a post a while ago attempting to identify each by their calls. The Redeye, Psaltoda moerens, the largest of them, is quite characteristic and reasonably well known. It is easily recognisable by its song, which builds to a crescendo of revving and yodeling buzzes.
But more common are the medium-sized cicadas of the Pauropsalta family; P. rubristrigata, and the smaller Black Squeaker, P. encaustica. En mass, they fill the bush with that persistent zizzing and fizzing that we hear. Heard up close, each species has quite distinct calls, with individuals giving quite a degree of variety, from steady buzzing to more rhythmical patterns such as “ch-ch-cher, ch-ch-cher”.
I realise it is unnecessary, given how ubiquitous they are now, but here is a recording of our local multi-species cicada chorus.
… and some images of a P. rubristrigata I came across the other morning. They are usually quite wary, so nice to get these close ups. Notice the red hind border of the abdominal segments.
