Found this beauty at the tide pool here in Collaroy yesterday. It's Psaltoda plaga, the black prince cicada, native to eastern Australia, one of the main sources of the electric, percussive, sometimes mind-quaking buzz that is part of the region's hot summers.
Here's a good ABC article on Australia's many cicada species, with life cycle info, and even some about the "legendary black prince." Excerpt:
A famous urban legend is that a chemist will pay good money for the wings of the elusive black prince cicada. And what do they do with the wings? They crush them up to make medicine of course! Though the exact type of medicine is never really specified.
A good deal larger than the cicadas I knew growing up in Buffalo, New York.
This one appears to have had its butt end eaten off. Oh joy:
That black you see is actually a hollow up into the poor buggers body cavity. They normally have a nice pointy end.
Belly up, and you can even see its long, black, tubular mouthparts that it uses to pierce plants to feed:
The mouth parts of the cicada are enclosed in a long, thin, beak-like sheath. The sheath (labium) passes backwards from the lower surface of the head between the legs when the insect is not feeding. It contains four fine, needle-like stylets used in feeding.
All in all a beautiful bug:
