Animals Wildlife That's No Leaf! 9 Amazing Images of Treehoppers By Anna Norris Writer Georgia State University Anna (Norris) Mitchell is a writer, editor, and photographer who loves capturing nature through her camera lens. our editorial process Anna Norris Updated June 06, 2018 Share Twitter Pinterest Email Animals Wildlife Pets Animal Rights Endangered Species (Photo: Mike Keeling/flickr) Funky bugs The treehopper family Membracidae is a wild and wacky bunch, the lesser known cousins of the less-than-appealing cicada. The slow process of evolution has led this family of bugs to split off into more than 3,000 separate species, each blending in with its own environment. Once you can determine what's a leaf and what's a bug, a closer look at treehoppers shows that they are a strange group. The most widely varying part of a treehopper is its pronotum (the area between the insect's head and its body), which grows upward and outward in myriad odd shapes.

In some areas, they are more plentiful, but in the United States, they haven't yet gained pest status. For now, we'll take the liberty of giving them "cute" status. Usually no bigger than about a half an inch, these tiny bugs have been extensively photographed using macro lenses, making this exercise much more informative.

Spiky thorns and stark coloration warn predators that this bug would make for a rather nasty snack. And speaking of snacking — treehoppers like to feast on the nutritious liquid contents of plant stems. Each species of treehopper has its own preferred tree. In the United States, you'll find these little guys most often on oak trees.

Though they don't seem like they need it, young treehoppers receive a lot of careful attention from their mothers. First the mother lays its eggs inside a stem, then it prepares the rest of the stem by poking little holes with its beak so the nymphs have easy access to grub. Then the mother treehopper will keep close watch to ensure none of her young wander off into the unknown. Some species of treehoppers are more communal, and many adult treehoppers pitch in to take care of their collective young. While female treehoppers do their best to hide, male treehoppers are the ones you'll see flitting from branch to branch, leaf to leaf looking for a mat. Upon landing, the male treehopper sends a pulse through the plant to try to communicate to a female via a kind of Morse code. Rex Cocroft of Natural History Magazine describes the sound as "a rich, bubbling down-sweep of tone and percussion that courses through the plant." If she's interested, the female responds with her own good vibrations, allowing the male to track her down.

Ants and treehoppers work together to live in a mutually beneficial relationship. Treehoppers eat sap from the stems of plants and secrete a substance called honeydew. Ants like to eat the honeydew, keeping the treehoppers' homes clean. Ants ward off predators while treehoppers do their best to camouflage the group so they can live in peace.

It vaguely resembles a tree frog with its bright green helmet and red accents. (Photo: Andreas Kay/flickr) The range of colors in these tropical treehoppers is astounding.
