Quick Summary

Dr. Chris Green from New Zealand’s Department of Conservation reports that the wētāpunga, the world's heaviest insect weighing up to 35 grams (as much as a sparrow or mouse), has been successfully reintroduced into the wild after extensive conservation efforts. Over 11,000 of these giant crickets were released onto predator-free islands and mainland sanctuaries since 2010, reversing their endangered status to "Threatened—Nationally Increasing." The breeding program involved innovative husbandry techniques that enabled the survival and thriving of this once-nearly extinct species.

Story summary

Once on the brink of extinction, the wētāpunga, known as the world's heaviest insect, is making a comeback thanks to a successful breeding program in New Zealand. Dr. Chris Green, an honorary research associate at New Zealand’s Department Of Conservation, co-authored a report in the New Zealand Journal of Zoology detailing the conservation efforts that led to the release of over 11,000 wētāpunga into the wild. Adult females can weigh up to 71 grams, heavier than a mouse, and their body length reaches up to 4 inches with a leg span of eight inches. The breeding program, carried out by experts at Butterfly Creek and Auckland Zoo, involved innovative techniques like feeding nymphs fresh foliage, fish flake protein, and leaf litter. This recovery effort marks a significant conservation achievement for the species, which was once widespread across New Zealand's North Island but nearly extinct due to habitat destruction by settlers.

Narrative

To bring the thick crickets back from the brink, experts at Butterfly Creek and Auckland Zoo had to rely on novel husbandry techniques, including feeding the nymphs fresh foliage, fish flake protein and leaf litter, the Guardian reported. They were also able to rear large numbers of the cumbersome crickets by keeping them in communal mesh cages.
