This treehopper looks more like an ant than the flying insect it is. Its costume, called a "helmet," grows out of its upper back. Treehoppers are masters of disguise - they might look like a leaf, a thorn, a twig, or bark. Some, like this ant lookalike, deter predators by mimicking other dangerous creatures. Others are for camouflage, helping them blend in with their background to hide from predators.
