Stick insect females can choose to reproduce by parthenogenesis (often referred to as virgin birth) producing only female offspring, or mate with males through sexual reproduction and have a mix of male and female offspring. The eggs of stick insects have a coating of calcium oxalate which makes them survive unharmed in the digestive tract of birds. It has been suggested that birds may have a role in the dispersal of parthenogenetic stick insect species, especially to islands.
