Children's stick insect is a medium sized stick insect. Females are larger and bulkier than males, and usually green, but can also be pinkish or cream. The wings are yellowish with bright patches of yellow and blue at the base. Males are slender and light reddish brown. Both males and both the males and females have two pairs of wings. Males are strong fliers, but females are too bulky to fly well. They rely on camouflage to avoid predators. When threatened, Children's Stick Insect will spread its wings showing the yellow and blue markings. Nymphs have a yellow stripe running along the length of the body. When at rest, the nymphs will align themselves on the leaf so yellow stripe aligns with the leaf midvein.
