How do praying mantis pee?

Praying mantises do not urinate in the same way mammals do. Instead, they excrete waste as a solid or semi-solid form, primarily through a process called Malpighian tubules, which filter waste from their hemolymph (a fluid equivalent to blood in insects). This waste is then expelled from their bodies through the anus. This method conserves water, which is crucial for their survival in various environments.
