What type of stick insects dont lay eggs?

Some species of stick insects, particularly certain parthenogenetic ones, do not lay eggs and instead reproduce through a process called parthenogenesis. In this form of reproduction, females can produce offspring without mating, resulting in clones of themselves. This is common in some populations of the genus Timema and other stick insects where males are rare or absent. As a result, these species can thrive in isolated environments without the need for males.
