What's bugging my mango?

[Clay]

My two grafted mango trees have been in the ground for just over two months and are doing well. They both have new flushes of branches with beautiful leaves. Every morning when I come out to have a look, I see a couple of these bugs on the new branches.  Not on the leaves, but on the branches. When you move toward them, they scoot sideways around the branch to hide on the other side. So I call them "sidewinder" bugs. I generally shake them off and they fly away. This one flew onto the fence where I could get a good picture of him. It is about 3/4 of an inch long. Can anyone identify it and tell me whether it is destructive? Should I worry?

Thanks!
