Spiny stick insect (Haaniella echinata) - Danum Valley, Borneo
A really cool group of insects, phasmatodea includes all leaf insects and stick insects (also known as walking sticks). Borneo is a hotbed of phasmid diversity as well with over 300 species being found there. This species was common in Borneo and remains one of the most impressive species I have ever seen. They are quite large and covered in spines and easily observed at night. This individual calmly sat on this leaf as I photographed him and went on my way. If he was on a woody surface he would have blended in very well but as is he stood out and was visible from far away sitting on this leaf as he was. Based on my observations I think that during the day these insects stay on woody surfaces that camouflage them well and then under the cover of night leave and crawl to the leafs in order to eat them while the darkness protects them from visually oriented predators.
