When I first started blogging I did a series on how cleverly insects disguise themselves and I am going to post them again as most of you never saw it.
Look at the first picture and see if you can spot the insect in it before looking at the second. :)

This caterpillar mimics the branch he is on perfectly even down to the lumps, bumps and notches. He is holding onto it with his feet. If you look at the bottom left hand corner, that is his eyes and he has a couple of hairs on his face.
