In Australia, cicadas are preyed on by the Australian cicada killer wasp (Exeirus lateritius), which stings and stuns cicadas high in the trees, making them drop to the ground, where the cicada hunter mounts and carries them, pushing with its hind legs, sometimes over a distance of 100 m, until they can be shoved down into its burrow, where the ...

They are around 3.5 to 4.5 centimetres in length. The species are active at night and are attracted to light, and rest under loose bark during the day. Unlike other cicadas, they do not make loud calls, but produce low intensity sounds transmitted through the substrate they are attached to, similar to other members of Auchenorrhyncha. [6]

In outbreak years, the cicadas do significant damage to the trees on which they lay eggs, especially saplings. The female cuts a slit in a twig in which to insert her eggs and this often causes the shoot to droop and defoliate. In larger twigs it may allow entry of disease organisms. The burden of feeding of the nymphs is also considerable.
