Fun facts

  • GeneralOne of the heaviest insects in the world: a gravid female reaches 70 grams.
  • récordIt can outweigh a sparrow, making it one of the heaviest insects known, and in New Zealand's ecosystems it fills the niche small rodents occupy elsewhere.
  • It is the largest insect in New Zealand and can weigh up to 71 g, more than a sparrow.
  • It survived only on Hauturu island, free of mammalian predators; after the Pacific rat was eradicated in 2004 the population began to recover.
  • It has been translocated to other predator-free islands: in 2018, 300 individuals bred at Auckland Zoo were released, and by then 4,300 had already been freed in the Hauraki Gulf.
  • It cannot fly, and as an adult it lives a nomadic life, moving about without settling anywhere.
  • It makes defensive sounds by rubbing pegs on the femur against ridges on the abdomen, with peaks of up to 40-50 kHz.
