Males do not have to be present for females to reproduce. If males are present and the female mates, eggs hatch within a few months. Parthenogenic eggs take longer to develop. It takes approximately three to four months for a nymph to reach adult stage. During this time, Australian walkingsticks go through six or seven molts.
Australian walkingsticks are nocturnal, remaining mostly motionless during the day.
Their enemies include birds and small mammals. If a predator approaches, walkingsticks will freeze in place, or sometimes even rock back and forth to mimic a twig shaking in the breeze. Their brown color and stick-like appearance also help them to look like a twig of the host plant and blend into their environment, camouflaging their presence from predators. Egg Toss Female walkingsticks lay eggs in a number of interesting ways, depending on their species. Some randomly scatter their eggs, others conceal them, while others bury their eggs.
