But that was the start of the wet season. Things change. Now the rainforest is filled with the songs of another cicada. This one is just as loud but prefers freeform jazz to the greengrocers' disciplined chorales.
The golden emperor (Anapsaltoda pulchra) is a Wet Tropics endemic. It is most abundant on the Atherton Tablelands, but is known as far south as the Kirrama Range. The call is difficult to describe, but Max Moulds gives it a go in his book Australian Cicadas:
One of the most pleasant-sounding cicada calls, powerful, somewhat flute-like in tone, composed of a succession of rolling burst of sound to some extent bell-like in nature, each element initially loud then falling in volume.
The specific epithet pulchra refers to the adult's beauty and the common name underlines it. From the turquoise eyes (olive green by day) to the emerald integument and golden sheen, this is a most regal cicada. As far as I'm concerned, it and its cohort can sing as loudly as they like and for a long as they like. I'm sure Angus Young would agree.
