I remember first seeing these stick insects as a kid, and they were very hard to spot. Even after seeing what appeared to be a walking twig, it still took a few seconds for my eyes to adjust to what I was witnessing. Then, after a few shakes of the head, it was like "that stick is alive!" Ha-ha! These creatures are all slender and elongated. There are differences in detail and color between the species of this insect and, sometimes, even between the specimens of the same species. The majority of them reproduce without the need for a male and/or any effort on their part. This is a good thing because most stick insects are female anyway, going by what I have read in the past. They are easily kept and are excellent laboratory insects if you like studying them because of their style of reproduction. I've even heard that some people like to keep them as pets, too.
