As saddlebacks prey on the wētā during the day, D. heteracantha are thus under constant predation pressure. [16] There is evidence suggesting that these rats have a negative impact on the population of these wētā, as is commonly the case with invasive rodents. [17] The removal of the kiore in 2004 was a success. The population size grew ...
Wētā is a loanword, from the Māori-language word wētā, which refers to this whole group of large insects; some types of wētā have a specific Māori name. [2] In New Zealand English, it is spelled either "weta" or "wētā", although the form with macrons is increasingly common in formal writing, as the Māori word weta (without macrons) instead means "filth or excrement".

This wētā species is endemic to New Zealand and populates regions in the southern half of North Island/Te Ika a Maui and the north-west of the South Island/Te Wai Pounamu .
The mating systems observed in giant wētā species like the Scree Wētā (Deinacrida connectens) and Cook Strait giant wētā (Deinacrida rugosa) likely led to the development of sexual dimorphism. where males develop lighter, more slender bodies and longer legs allows them to cover distance more efficiently has developed.
A number of animals prey on the Cook Strait giant wētā, including birds and reptiles such as the tuatara. As a defence against predators the Cook Strait giant wētā will raise its spiked legs over its head and wave them up and down while making a hissing sound by rapidly rubbing together the overlapping plates on its upper body.

Tree wētā are nocturnal and arboreal, hiding in hollow tree branches during the day and feeding at night. [7] Their diet consists of leaves, flowers, fruit and small insects. [ 8 ] [ 9 ] Males have larger heads and stronger jaws than females, though both sexes will stridulate and bite when threatened.
