Stick Insect (Carausius morosus) lives in tropical rainforests across Southeast Asian forests. It feeds on leaves and twigs.
Fascinating facts about the Stick Insect
- Culture stocks are parthenogenetic females that can reproduce without mating, meaning a single female can start a whole colony. Only 1 in 1000 are male, and although in captivity, gynandromorphs (individuals with both female and male characteristics) are sometimes reared, so true males are virtually absent in the wild. Females are elongated and about 80-100 mm (3-4 in) in length, ranging from a light green to a darkish brown in colour.
- When disturbed, the major defence method is feigning death, the body becoming rigid, and the legs held along the line of the body. They may also be found swaying to mimic the movement of foliage in wind, even if it is just a breath or a small movement of air. The insects usually feed between dusk and dawn, when they are active, and during the day they rest, often with legs in line with the body, on their food plants or anywhere where they can stay comfortably.
- Due to their inconspicuous nature, accidental introductions of C. morosus have been recorded around the world, including Great Britain, Portugal, South Africa and the United States, where in some cases they have become a pest. Studies at the San Diego Zoo found the introduced species on a large number of ornamental plants. Their ability to thrive without males and to blend into foliage.

About the Stick Insect
In the dappled light of a forest glade, the stick insect moves with a deliberate slowness, its elongated body swaying gently as it navigates the intricate network of twigs and leaves. With each painstaking step, it embodies the very essence of patience, its remarkable mimicry of a twig allowing it to blend seamlessly into its surroundings, a masterful deception that has evolved over millennia. As it pauses to survey its domain, the stick insect's delicate antennae twitch with a quiet awareness, a testament to the enduring, if enigmatic, presence of this intriguing creature.
