I have a bug problem in my garden. There are these i guess "caterpillars" next to little cocoons around them attached to my tree. and my tree went from being elegant and full and green. to every single leaf eaten. they dont look resembling normal caterpillars nor cocoons. if you look at the tree you can see them all shaking and if you procure close you can actually see them sticking there head out and eating stuff. does anyone have any view what they are called and how to get rid of them.??

here are some pictures of them
