There is little known on the habitat of the Fijian stick insect, however, its body structure (a flattened body, fringes of hair and general appearance) is typical of an insect living on tree trunks covered with lichens. In 1934, a female Fijian stick insect was found crawling on the near a fallen tree trunk, on the ground in the forest on the western side of Taveuni, at 1,100 feet. This individual was captured and kept in captivity for six days until it died. During the six days of captivity it laid eggs. The eggs were kept for more than four months but they did not hatch, and upon dissection it was discovered that they had not undergone embryonic development. The female kept in captivity did not eat any of the leaves of the tree near which it was found. Another female specimen that was captured later in the same year was dissected to determine the diet. Fragments of leaves and yellow substances resembling pieces of fruit from the Taveuni forest were found, suggesting that the Fijian stick insect is herbivorous. Male specimens of the Fijian stick insect have never been encountered, but they surely must exist as suggested by the infertile eggs laid by the female in captivity, which was not fertilised as the female did not mate. Other than the fact that it cannot fly, and has such incredible camouflage that it is rarely seen, there is little known on this endemic insect. The differences between females and males are not known, and neither are the breeding time and the amount of time between the moulting stages.

The Fijian name of this insect literally means “piss in the eye”, and many Fijians would warn you against touching the insect or getting too close to it out of fear that it could piss in your eye and blind you. Though many may believe this to be mythical, there is scientific evidence that most stick insects do indeed have special glands which can secrete a very acrid poison when the insect is alarmed.
