The common name treehoppers broadly applies to three families--Aetalionidae, Melizoderidae, and Membracidae--which together include at least 3270 described species. Treehoppers are known for the remarkable diversity of their shapes and behaviors. Membracidae is the largest treehopper family (more than 400 genera and 3200 species), followed by Aetalionidae (6 genera, 42 species), and Melizoderidae (2 genera, 8 species).

Distribution

Although treehoppers occur in all major zoogeographic regions, Europe has only a few species, and no indigenous species are known from New Zealand or Madagascar. Aetalionids are primarily Neotropical, but two species of Aetalion are recorded from the Nearctic region (Arizona and Florida), and one genus (Darthula, with two species) occurs in the Indomalayan region. Melizoderids are known only from Chile and Argentina. Membracidae, the largest and most widespread family, has 9 subfamilies, 8 of which are restricted to the New World (one Nearctic species of Smiliinae: Ceresini is introduced and widespread in the Palearctic). The remaining subfamily, Centrotinae, is the largest, with 6 New World tribes and 17 Old World tribes.

Morphology

Treehoppers, which have 3 or fewer longitudinal rows of enlarged setae on the hind tibia, often have an oddly-shaped pronotum. In nearly all adults of the family Membracidae (2-24 mm in length) the pronotum is noticeably enlarged and extends posteriorly over the scutellum. Also, in membracid males, distinct lateral plates are differentiated from abdominal tergum IX, and, in nymphs (many of which have dorsal spines), abdominal segment IX forms an unbroken sheath around segment X. Melizoderid adults (4-6 mm in length) have an anterior pronotal horn, but lack posterior pronotal processes--in melizoderid nymphs abdominal tergum IX completely conceals the anal orifice dorsally. Aetalionids (3-30 mm) may have various modifications of the head (simple or with a pair of dorsal horns), pronotum (simple or with a middorsal process), or scutellum (simple or with an elevated keel). Also, in aetalionids the prothoracic trochanter and femur are fused, and females have abdominal tergum IX produced posteroventrally.

Ecology and Behavior

Treehoppers, like many Auchenorrhyncha, communicate by vibrational songs transmitted through stems and leaves of their host plants. Treehoppers are recorded from many herbaceous and woody hosts representing more than 100 plant families. Polyphagy is widespread among tropical treehoppers, but most Nearctic species are found on a single host genus or family. As a by-product of ingesting large quantities of plant sap (phloem), treehoppers secrete a sugary substance called "honeydew", which may serve as food for various opportunistic ants, bees, or wasps. Thus, treehoppers frequently benefit from interactions with ants that provide "house cleaning" services and sometimes protect the hoppers from predators in exchange for the honeydew secretions. Many treehoppers are gregarious or even subsocial, with some even guarding their eggs and immatures. Both parental care and ant-mutualism are common among aetalionids as well as membracids. Aetalionids and some membracids deposit egg masses on the surface of plants. Most membracids, however, insert the eggs into plant tissue--in so doing, a few species injure their hosts so seriously that they are considered plant pests.
