There are over 70 species of wētā in New Zealand
There are eleven species of giant wētā, most of which are larger than other wētā, despite the latter also being large by insect standards
The name wētā comes from the Maori word wētāpunga, or “God of Ugly Things” .The genus name, Deinacrida, means “Terrible Grasshopper.”
The giant wētā’s close relatives include the Carnivorous Tusked Wētā, the Tree Wētā, and the Cave Wētā
Giant wētā are endemic to New Zealand and all but one species are protected by law because they are considered at risk of extinction

The largest species of Giant Wētā is the Little Barrier Island giant wētā, also known as the wētāpunga. One example reported in 2011 weighed 71 g (2.50 oz)
[Deinacrida mahoenui] is endemic to the area of Mahoenui, New Zealand, and the world population for some time was restricted to a single patch of introduced gorse on farmland.

Large species can be up to 10 cm (4 in), not inclusive of legs and antennae, with body mass usually no more than 35 g (1.2 oz). One gravid captive female reached a mass of about 70 g (2.47 oz), making it one of the heaviest insects in the world and heavier than a sparrow. This is, however, abnormal, as this individual was unmated and retained an abnormal number of eggs
Many giant wētā species are alpine specialists. Five species are only found at high elevation in South Island. The scree wētā D. connectens lives about 1,200 m (3,900 ft) above sea level [8] and freezes solid when temperatures drop below −5 °C (23 °F)
Fossils found from the Triassic period 190 million years ago show striking similarities to the wētā that inhabit New Zealand today

It's a shame there isn't more oxygen in the atmosphere to allow them to grow bigger.
Both a shame and happy coincidence, I wouldn't fancy having a seagull sized dragonfly dive bombing me!
Incidentally, I'm planning some posts on prehistoric insects and invertebrates for the near future which I'm looking forward to researching....so plenty of large 'monsters' from the past to checkout
Once the algae bloom from raised CO2 levels due to global warming leads to an increase of oxygen levels, there might be giant insects again.
I'll look forward to the giant dragonflies stealing my sandwiches instead of seagulls, if I'm not an irradiated husk of carbon by then....
