The Auchenorrhyncha suborder of the Hemiptera contains most of the familiar members of what was called the "Homoptera" – groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha.

Phylum: Arthropoda
Class: Insecta
Order: Hemiptera
Suborder: Auchenorrhyncha
Infraorders

Distributed worldwide, all members of this group are plant-feeders, and many are vectors of viral and fungal diseases of plants.

It is also common for Auchenorrhyncha species to produce either audible sounds or substrate vibrations as a form of communication. Such calls range from vibrations inaudible to humans, to the calls of many species of cicadas that can be heard for hundreds of metres, at least. In season, they produce the most characteristic and ubiquitous noise of the bush.

Etymology edit

The word "Auchenorrhyncha" is from the Greek αὐχήν, 'neck, throat' and ῥύγχος, 'snout'.[citation needed]

Classification edit

 
Jikradia olitoria, nymph (Cicadellidae)
 
Aphrophora sp., nymph (Aphrophoridae)
 
Metcalfa pruinosa, nymphs (Flatidae)

Debate and uncertainty as to whether the Auchenorrhyncha is a monophyletic group or not is ongoing; some authors, believing it was not, split it into two suborders, the Clypeorrhyncha (= Cicadomorpha) and the Archaeorrhyncha (= Fulgoromorpha).[1] In the last 10 years, there has been evidence to support the monophyletic interpretation, and the most recent research indicates the Auchenorrhyncha are in fact a monophyletic lineage.[2] A classification of the Auchenorrhyncha is:[3]
