Spur-throated Locust

Description:

A Grasshopper with a leaf on its leg. "The spur-throated locust is readily distinguished from other pest species of locusts and grasshoppers by its large size and the presence of a spur, or throat-peg, between the front legs. The adults are pale brown in colour with white stripes and dark markings on the thorax. The hind-wings are colourless or have a bluish tinge. The shanks of the hind legs are straw or mauve coloured and bear two rows of dark-tipped white spines. Adult males measure 55–65mm long and females are 70–80mm long."

Habitat:

Near the waster water treatment wetlands.

Notes:

Thank you Rob for the identification. Thank you to the Curator of Entomology at Western Australian Museum for confirming the identification and for the following information: They are mating - or "mate guarding" where the male rides around on the female after mating, trying to ensure other males don't mate with her.
