Spiny Stick Insect, Extatosoma tiaratum

These insects are native to Australia and New Guinea. The females’ bodies are covered in spines and can reach lengths of 5 – 8 inches. Females have small wings but cannot fly. Males lack the spines except for on the head; are smaller and are winged. Most are light brown, but their color depends on the conditions in which they are kept, although it is not entirely sure which conditions you need to provide to induce your stick insects to change color.
When threatened, they will lift their front legs and curl up their abdomen in a “scorpion” pose. Adults can release a defensive odour, which apparently smells similar to peanut butter and vinegar.
