A very impressive portrait!
I wonder if you are entirely sure that this is the same creature you've seen in National Geographic movie?
For 99% this is a Treehopper (family Membracidae). These insects are plant suckers. They feed on sweet juices sucked usually from plant stem. Feeding treehoppers expel droplets of sugary honeydew just as aphids do.
They definitely aren't predators, but sometimes they can attack insects or spiders that are trying to eat their youngs. They are known from being a very good parents.
The spike or shieldlike things on the body of treehoppers are just a way to camouflage themself. When such insects sits on stem it looks like a part of the plant. Such thorns are also good for protection.
I can't give you exact ID becuase I have no idea about species living in your country, but I'm quite sure this is a treehopper.
It's a nice picture with good framing and POV. You have some good details here.
excellent capture and great detail.
Hi, looks to me like a weevil. Weevil is the common name for beetles of the snout beetle family Curculionidae. I can't give you the exact ID hope you can find it now you know the family name.
Very nice shot of an interesting little skink.
