Knowra Wētā Wētā Wētā are large, mostly flightless insects native to New Zealand. The group includes tree, ground, cave, and giant wētā, which occupy varied habitats and ecological roles.
Orthoptera : An insect order that includes grasshoppers, crickets, and katydids. Wētā belong to this order, sharing its enlarged hind legs and sound-producing lineages.
New Zealand island restoration : The ecological recovery of islands in New Zealand through pest removal and habitat protection. Restored islands provide refuges where vulnerable wētā populations can recover.
Giant wētā : Large, mostly flightless New Zealand insects in the genus Deinacrida. These famous wētā include some of the heaviest insects known.
New Zealand biogeography : The study of the distribution and evolutionary history of organisms in New Zealand. It explains the geographic setting in which wētā diversified.
Introduced mammalian predators in New Zealand : Mammals brought to New Zealand by people, including rats, mustelids, and cats, that prey on native wildlife. These predators consume wētā and have contributed to declines in vulnerable populations.
Anostostomatidae : A family of orthopteran insects that includes wētā and king crickets. Many familiar wētā, including giant and tree wētā, belong to this family.
Ecological monitoring : The repeated measurement of organisms or environmental conditions to detect ecological change. Wētā presence and abundance can indicate changes in habitat quality and predator pressure.
Tree wētā : Arboreal New Zealand orthopterans in the genus Hemideina. Tree wētā shelter in cavities and defend communal galleries in trees.
Zealandia : A largely submerged continental mass in the southwest Pacific that includes New Zealand. Wētā evolution is part of the longer biological history of Zealandia.
Polynesian rat : A small rat, Rattus exulans, introduced to many Pacific islands, including New Zealand. Its arrival increased predation pressure on native invertebrates and other wildlife.
