- Size
- Length: 50–70 mm
- Lifespan
- 10–12 months
- Diet
- Leaves of native understory shrubs and small trees.
- Habitat
- Native forest understory particularly in damp shaded areas with dense foliage.
- Range
- North Island native forests particularly in Waikato and Bay of Plenty.
- Endemism
- Endemic
- Main Threats
- Habitat loss and predation by introduced mammals. Data deficiency hinders management.
- Population
- Localised populations known from specific forest remnants. Status uncertain due to limited surveys.
- Conservation Status
- data_deficient
- Human Risk
- harmless
- Handling Note
- rarely seen due to cryptic colouration, leave undisturbed in forest habitat
- Conservation Note
- Endemic stick insect with limited records from scattered North Island forest remnants, requiring further survey to determine population trends and conservation needs.
- Assessment

- Te Ao Māori
- Lack of specific Māori names reflects limited historical documentation of this cryptic species. Its elusive nature meant it was often overlooked in traditional ecological knowledge systems focused on more visible fauna. Modern science struggles similarly with detection.
Rain falls on the canopy. The Stick Insect does not move. Water beads on its exoskeleton. It waits for the dryness to return. This species is rarely seen. It hides in plain sight. The body mimics dead twigs perfectly. Even the colour matches decaying wood.
It is found in scattered locations across the North Island. Records exist from Waikato and Bay of Plenty forests. Southern distribution is unclear. Survey efforts have been sparse. The insect prefers undisturbed native bush. Logging and land conversion have reduced available habitat.
Threats include habitat fragmentation. Introduced mammals like rats and mice may prey on eggs or nymphs. Birds also pose a risk. The population is likely declining but data is insufficient to confirm trends. Conservation status reflects this uncertainty. More research is needed.
Habitat requirements are specific. Damp understory with dense ground cover is essential. Leaf litter provides protection for eggs. Host plants include various native shrubs and small trees. The insect feeds nocturnally. Daylight hours are spent motionless.
Diet consists of leaves from native plants. Specific preferences are not fully documented. Observations suggest feeding on mānuka and other common understory species. Digestion is efficient. Nutrient extraction is maximised from low-quality foliage.
Life span is approximately one year. Eggs overwinter in soil. Hatching occurs in spring. Nymphs grow slowly. Moulting happens five or six times. Adults appear in summer. Mating occurs briefly. Females lay eggs before dying. The cycle is tied to seasonal moisture levels.
