These beautiful animals do not have a common name but their scientific name is Haaniella dehaani.  They are a very spiny species of stick insect from the rainforests of Sarawak on the island of Borneo.  This first picture is a close-up of the face of a mature female, showing off her unusual looks! 

The picture directly below is of two mature females, which as you can see are quite large and very attractive!

These two pictures are of a mature male which is really quite spiny all over, and certainly considerably more spiny than the females above!

I have successfully bred this species a couple of times so have been able to watch them grow from newly hatched nymphs into fully grown adults, which has been fascinating to see.  The ova of this species are velvety in appearance and are quite large considering the adult size, and look like this:

The picture below is of four newly hatched nymphs, some of which grew into the adults above!  The nymphs are relatively large for newly hatched stick insects because of the large size of the ova.  The nymphs take just 6-7 months to mature, which as you can see is still quite a large change in size despite them starting their lives as big as they do!

Nymphs produced from eggs laid by the same female can hatch for some time following the first ones hatching, because of the numbers of eggs the adult female can lay over a period of time.  The pictures below show a newly hatched nymph next to one of its older siblings at about 6-8 weeks old, showing the amazing size difference between nymphs hatching just weeks apart!
