These remarkable stick insects do not have a common English name and are known only by their scientific name of Haaniella grayii.  They originate from the rainforests of Sarawak, which is an area on the island of Borneo in southeast Asia.

The male above is certainly one of the spikiest stick insects I have ever seen!  As in many species of stick insect the male looks very different to the female, a subadult of which is pictured here:

Here they are together, with the male on the left hand side.

I have had excellent success breeding a different but closely related species, known as Haaniella dehaani also from the rainforests of Sarawak.  This is a female of that species:

The male is certainly very spiky like the male of Haaniella grayii but he isn't quite as strikingly beautiful!

Their newly-hatched babies or nymphs are very cute indeed as you can see here!
