Ants are fond of the eggs of these stick insects, and take them into their galleries, where they eat only the top portion of the eggs. This protects the future stick insects from other predators. Once they emerge, the stick insect nymphs quickly leave the ants’ nest to feed, mimicking the ants’ movements. Stick insects belong to the order Phasmida, named for the Greek word “phasma”, which means apparition or ghost.
In addition to reproducing sexually, stick insects are able to reproduce by means of parthenogenesis: females can lay fertile eggs without being fertilized by a male. Such eggs produce only females.
