Adults are capable of jumping many times their height and length, giving the group their common name, but many species are best known for their plant-sucking nymphs which produce foam shelters, and are referred to as "spittlebugs". Taxonomy Traditionally, most of this superfamily was considered a single family, the Cercopidae, but this family has been split into three families for many years now: the Aphrophoridae, Cercopidae, and Clastopteridae. More recently, the family Epipygidae has been removed from the Aphrophoridae.JOURNAL, A new family of froghoppers from the American tropics (Hemiptera: Cercopoidea: Epipygidae), 2001

This characteristic spittle production is associated with the unusual trait of xylem feeding. Whereas most insects that feed on sap feed on the nutrient-rich fluid from the phloem, Cercopidae utilize the much more dilute sap flowing upward from the roots via the xylem. The large amount of excess water that must be excreted and the evolution of special breathing tubes allow the young spittlebug nymphs to grow in the relatively protective environment of the spittle.BOOK, Marshall, Stephen A., Insects: Their Natural History and Diversity, 2017, Firefly Books, Buffalo, NY, 978-1-77085-962-3, 104, Second, Normally an animal should not be able to survive on a diet so low in nutrients, but the insects' digestive system contains symbiotic bacteria that provide them with the essential amino acids.Two bacteria allow spittlebugs to thrive on low-nutrient meals May 28, 2020 www.sciencedaily.com accessed 11 May 2023The foam serves a number of purposes. It hides the nymph from the view of predators and parasites, and it insulates against heat and cold, thus providing thermal control and also moisture control; without the foam, the insect would quickly dry up. The nymphs pierce plants and suck sap causing very little damage; much of the filtered fluids go into the production of the foam, which has an acrid taste, deterring predators. A few species are serious agricultural pests.A small family in the group, the Machaerotidae, known as the tube spittlebugs, is an outlier among the Cercopoidea because the nymphs live in calcareous tubes rather than producing foam as in the other families.File:Spittlebug nymph (unknown species), East Lyn River, Devon, UK - Diliff.jpg|The spittlebug nymphImage:Spittlebug4383.JPG|Nymphal form of spittlebug surrounded by foam for protection and moisture Adults Adult froghoppers jump from plant to plant; some species can jump up to {{cvt|70|cm}} vertically: a more impressive performance relative to body weight than fleas.

Clark (April 29, 2017) Garden Ambition, accessed 11 May 2023Many species of froghopper resemble leafhoppers, but can be distinguished by the possession of only a few stout spines on the hind tibiae, where leafhoppers have a series of small spines. Members of the family Machaerotidae greatly resemble treehoppers, due to a large thoracic spine, but the spine in machaerotids is an enlargement of the scutellum, where treehoppers have the pronotum enlarged. Members of the family Clastopteridae have their wings modified to form false heads at the tail end, an antipredator adaptation. Many adult Cercopidae can bleed reflexively from their tarsi, and the hemolymph appears to be distasteful; they are often aposematically colored. Evolutionary history The oldest froghoppers are known from the Early Jurassic. Mesozoic froghoppers are divided into two main families, Procercopidae known from the Early Jurassic to early Late Cretaceous of Asia, which are thought to be ancestral to living froghoppers, and Sinoalidae, which is known from the late Middle Jurassic and early Late Cretaceous of Asia.JOURNAL, Chen, Jun, Wang, Bo, Zheng, Yan, Jiang, Hui, Jiang, Tian, Bozdoğan, Hakan, Zhang, Junqiang, An, Baizheng, Wang, Xiaoli, Zhang, Haichun, February 2020, Taxonomic review and phylogenetic inference elucidate the evolutionary history of Mesozoic Procercopidae, with new data from the Cretaceous Jehol Biota of NE China (Hemiptera, Cicadomorpha), Journal of Zoological Systematics and Evolutionary Research, en, 58, 1, 174–193, 10.1111/jzs.12349, 0947-5745, free, The genus Qibinius the Middle Jurassic Yanan Formation of China mixes characters of both families and cannot be assigned to either.JOURNAL, Fu, Yanzhe, Huang, Diying, 2020-05-28, A new fossil cercopoid from the middle Jurassic Ordos and Jiyuan basins, northern China (Hemiptera, Cicadomorpha),weblink Historical Biology, 33, 10, en, 2025–2030, 10.1080/08912963.2020.1765167, 219747247, 0891-2963, The genus Cercopion from the Aptian aged Crato Formation of Brazil appears to be derived from the Procerocopidae and closely related to the crown group.
