Haaniella saussurei

Haaniella saussurei is a species of stick insect native to Borneo and a typical representative of the subfamily Heteropteryginae. The occasionally used common name Saussure's Haaniella refers to the species name. As is typical for most of the species of the genus Haaniella, both sexes of Haaniella saussurei have many sharp thorns on the body and legs and very short wings. The front wings, which are designed as tegmina, completely cover the short hind wings (alae). The latter are transformed into stridulation organs and are used to ward off enemies. The females are often patterned in contrasting light and dark brown, but can also only be dark. With increasing age, the contrast in the patterned females decreases and the animals become darker. Egg-laying females have a conspicuously plump abdomen, the end of which is formed by a spike-like laying apparatus that surrounds the actual ovipositor. The dorsal end segment of this ovipositor is formed by the eleventh tergum. This structure, known as the supraanal plate, is characterized by four fine teeth at the end in the females of Haaniella saussurei. Older juvenile stages have strong pink colored membranes in the area of... Wikipedia →

Likely
About 50% of wildlife watchers report a Haaniella saussurei sighting in Bako National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 33 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March and June
In those months about 60% of wildlife watchers report a Haaniella saussurei in Bako National Park on a given day, against about 10% in October, the lowest month.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Haaniella saussurei sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Bako National Park, in our data
Bako National Park is the only park on Wallace's Line with enough records to rate Haaniella saussurei sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Haaniella saussurei is recorded against all the insects logged in Bako National Park (35 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
