Water Scorpion grow to over 50mm long they can extend the tube on their backs out of the water to breathe air like a snorkel while swimming. They can ambush fast swimming prey such as small fish catching them between their front legs and stabbing them with their pointed probiscus. Known as Toe-biters able to inflict a nasty nip although this specimen played dead when disturbed. Water Scorpions are also capable fliers and inhabit waterholes over much of Australia.

This cicada image is currently an unidentified species? These cicadas are some of the largest and loudest in Australia and are found in tall Open Eucalypt forests. The nymphs live underground for several years and suck on the roots of trees for survival. They emerge enmasse, and demonstrate “predator satiation” with so many out at once the species is sure of survival from predators.
These True Crickets are identified by their long antennae. They are ground dwelling and usually active at night when males construct complex love songs. Crickets have their ears on their front legs and are omnivorous scavengers, feeding on decaying plant matter, fungi and emergent plants. These important beneficial insects are in turn prey for lizards and birds and are considered a delicacy in some countries and a good luck charm in others.
Both nymph and adult bugs are sap suckers. They are creamy white with pink wing edges , this one had a bluish tinge and around 15mm long. These planthoppers usually walk very slowly to avoid detection, they are also strong jumpers which is used as a defensive mechanism. ”Planthoppers are often vectors for plant diseases, especially phytopasmas which live in the phloem of plants and can be transmitted by planthoppers when feeding” A new species for the wildlife refuge.
