Physical Characteristics

Australian stick insects vary in size and appearance, with some species reaching lengths of up to 30 centimeters. Their elongated bodies and legs resemble sticks or branches, providing them with excellent camouflage. The coloration of these insects ranges from green to brown, further enhancing their ability to blend into their environment.
