Carausius morosus is a species of stick insect native to the tropical forests of Southeast Asia. Known for its remarkable camouflage, it resembles twigs or branches, helping it evade predators. This herbivorous insect primarily feeds on leaves, particularly from plants like bramble and blackberry. These stick insects are popular in the pet trade due to their unique appearance and relatively easy care requirements. They thrive in warm, humid environments and require a diet of fresh foliage. Carausius morosus can reproduce through parthenogenesis, allowing females to produce offspring without mating.
