  • Wētā have been around long enough to see dinosaurs come and go and to evolve into more than 70 different species, all of them endemic to New Zealand.

    Wētā have become icons for invertebrate conservation in New Zealand because many species are threatened or endangered. There are more than 70 species of wētā in New Zealand, 16 of which are at risk.

    There are five broad groups of wētā:

    • Tree wētā
    • Ground wētā
    • Cave wētā
    • Giant wētā
    • Tusked wētā

    Wētā are mainly herbivorous in the wild, but are also known to eat insects.

    They are nocturnal and live in a variety of habitats including grassland, shrub land, forests, and caves. They excavate holes under stones, rotting logs, or in trees, or occupy pre-formed burrows.
