One of the heaviest insects in the world, the giant weta is an example of island gigantism—the phenomenon in which isolated species evolve to become unusually large in the absence of restraints such as predators. Giant wetas are found primarily on New Zealand’s offshore islands, having been driven almost to extinction elsewhere in New Zealand by introduced mammalian predators. They are fairly tame, passive insects that resemble giant grasshoppers. How heavy are the largest wetas? Discuss
