This is the "nymph" of a Fulgoroid plant-hopper insect  (Flatidae nymph). It turns into an insect with a completely different shape as adult. Because of its appearance it is nicknamed a "Cotton Bug". Its body is covered with waxy filaments that look like cotton threads. It can jump when threatened. The white threads serve as a second line of defence. When caught i.e by a bird, its filaments remain in the beak of the birds and the insect makes off.
