General Information 

This large species of stick insect is native to Queensland and New South Wales but has extralimital distribution as far away as New Guinea. 

Female adult E. tiaratum are covered with thorn-like spikes for defense and camouflage. Their long, rounded bodies grow to about 5 to 8 inches (20 cm) long. Exhibiting the sexual dimorphism of many similar insects, males are small and thinner, growing only about 11 cm in length and have three ocelli. Males lack the thorny growths except for spikes around their faces. They have long wings and are good flyers who readily take to the air if disturbed or in search of females

Both sexes, when threatened, adopt a threat pose, standing on the front and middle legs, pointing their abdomen up or to the side in a sort of "scorpion" pose.

This herbivorous species will feed on eucalyptus in the wild. Captive populations will feed readily on bramble, rose, hawthorn and oak.
