Haaniella saussurei is a species of stick insect native to Borneo and a typical representative of the subfamily Heteropteryginae.

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.

This structure, known as the supraanal plate, is characterized by four fine teeth at the end in the females of Haaniella saussurei.

This striking coloring serves as a warning, as the animals defend themselves with their thorny hind legs.

The hind legs are extended in the air together with the abdomen and fold when touched, so that they pinch an attacker.

Both in the coloring of the body and the wings, they are very similar to the males of Haaniella grayii, although these usually show even more intense shades of green.

At the same time he described the species Haaniella echidna using a male from the collection of Morgan Hebard deposited at the Academy of Natural Sciences of Drexel University in Philadelphia.

He also considered the species described by Kirby to be a subspecies and named it Haaniella echinata saussurei.

The breeding stocks go back to specimens collected by Philip E. Bragg and Ian Abercrombie in 1994 in Sarawak, more precisely in Tarum near Debak.

In these, a substrate that is suitable for laying eggs and is always slightly moist should cover the terrarium floor by 5 to 10 centimetres (2.0 to 3.9 in).

The humidity and temperature in the terrarium should be rather high in order to do justice to the tropical origin of the animals.
