Treehopper..

Treehoppers (more precisely typical treehoppers to distinguish them from the Aetalionidae) and thorn bugs are members of the family Membracidae, a group of insects related to the cicadas and the leafhoppers. There are about 3,200 known species of treehoppers in over 600 genera. They are found on all continents except Antarctica, although there are only three species in Europe.

They are best known for their enlarged and ornate pronotum, which most often resembles thorns, apparently to aid camouflage. But in some species, the pronotum grows to a horn-like extension, and even more bizarre and hard-to-describe shapes are also found.

Thorn bugs, due to their unusual appearance, have long interested naturalists. There is no way to tell the male and females apart other than looking at the male genitalia. Individual treehoppers usually live for only a few months, but they belong to a lineage that is at least 40 million years old. More info in http://en.wikipedia.org/wiki/Treehopper
