These fabulous stick insects are Kylie and Danni, two adult females of a species of Australian stick insect named Onchestus rentzi, more commonly known as the CROWNED STICK INSECT due to their unusual head structures!

As you can see above they are certainly stick insects which truly do resemble sticks and the images below clearly show their unusual head structures!

The ova (eggs) of this species also have a particularly unusual shape.  Many stick insect ova have a distinctive shape, colour or pattern which is unique to that particular species and this is no exception! 

Newly hatched nymphs of Onchestus rentzi are quite small and fragile-looking, being particularly slender and long-legged as you can see below!

As they develop they become much more like their parents as you can see here!
