Despite its formidable size, the giant weta follows a primarily herbivorous diet, feeding on leaves, fruits, and other plant materials. This gentle eating habit contrasts sharply with its imposing appearance.

Tracing its origins back over 190 million years, the giant weta stands as a living testament to insect evolution. It provides scientists with crucial links between ancient species and their modern-day counterparts.

New Zealand’s geographic separation allowed the giant weta to evolve without the competition and dangers present in other regions. This unique evolutionary journey makes it an important subject for ecological research.

Preferring the cover of darkness, the giant weta is most active at night. This behaviour helps it forage safely while reducing the risk of encounters with predators in its forest and grassland habitats.
