THEY RELEASED 11,000 GIANT INSECTS. NOW THE POPULATION IS INCREASING.
Fourth- and fifth-generation wētāpunga are now breeding without help on two islands.
New Zealand conservationists have bred and released 11,000 wētāpunga — the country’s heaviest insect — into 10 new wild sites. Monitoring has found self-sustaining fourth- and fifth-generation populations on two islands, and the species is now classed as Threatened–Nationally Increasing.
WHAT HAPPENED
Beginning with the last natural population on Hauturu-o-Toi / Little Barrier Island, Auckland Zoo and conservation partners built a captive-breeding and translocation programme. Across 45 releases over roughly 15 years, 11,000 animals were moved to predator-free islands and sanctuaries. Follow-up monitoring found wild-born descendants reproducing without continued releases at Motuora and Tiritiri Matangi.
WHY THIS IS HOPESLOP
Invertebrate conservation rarely gets a number this cinematic: 11,000 tiny giants, moved one careful generation at a time. It is not a complete restoration, but it is proof that patient breeding, protected habitat and years of follow-through can turn one refuge into a growing network of wild populations.
