White apple leafhopper

Saw this a few years ago but my camera was rubbish back then and I havent seen it again until recently!
This insect is really cool, its so pretty, just like a snowflake!
It does not have any wings but can jump.
The things at the back are not legs and it would appear to be a spider if you look at it from a distance.
However those things at the back compact together just like a peacock when it feels scard!

After looking at the close up its seems to look like  skeleton fish!
