Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Deinacrida heteracantha faces severe population decline primarily due to habitat destruction from agricultural conversion and urban development across its limited range. Introduced mammalian predators, particularly rats and stoats, pose a significant threat to both adults and eggs, as these large insects have no evolutionary defenses against such predators. Forest fragmentation has isolated remaining populations, reducing genetic diversity and limiting dispersal opportunities for this flightless species.

Threat summary

Habitat

This species inhabits native forests, scrublands, and grasslands, typically found under logs, in tree holes, or among dense vegetation where it can shelter during daylight hours. It requires areas with sufficient ground cover and native plant species that provide both food resources and protection from predators.

Frequently asked questions

Why is Deinacrida heteracantha classified as Vulnerable?
Deinacrida heteracantha is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Deinacrida heteracantha faces severe population decline primarily due to habitat destruction from agricultural conversion and urban development across its limited range. Introduced mammalian predators, particularly rats and stoats, pose a significant threat to both adults and eggs, as these large insects have no evolutionary defenses against such predators. Forest fragmentation has isolated remaining populations, reducing genetic diversity and limiting dispersal opportunities for this flightless species.
Where does Deinacrida heteracantha live?
Deinacrida heteracantha occurs in New Zealand. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
