Xylem-feeding
Guides
Cercopidae
froghoppers, spittlebugs
Cercopidae is the largest family of Cercopoidea, a group of xylem-feeding insects in the hemipteran suborder Auchenorrhyncha. Commonly called froghoppers or spittlebugs, these insects are known for the frothy protective masses produced by nymphs and the powerful jumping ability of adults. A 2023 phylogenetic study elevated the New World subfamily Ischnorhininae to full family status as Ischnorhinidae, leaving Cercopidae sensu stricto as a monophyletic Old World group comprising two subfamilies: Cercopinae and Cosmoscartinae. Members are significant agricultural pests of forage grasses, sugarcane, and turfgrass throughout tropical and subtropical regions.
Cercopoidea
froghoppers, spittlebugs
The superfamily Cercopoidea comprises hemipteran insects commonly known as froghoppers or spittlebugs. Adults possess powerful hind legs enabling jumps up to 70 cm vertically and 100 times their body length. Nymphs are renowned for producing foam shelters ("cuckoo spit") from excreted xylem sap, within which they develop concealed from predators and environmental extremes. The group exhibits xylem-feeding, an unusual trait among sap-feeding insects requiring symbiotic bacteria to supplement nutrient-poor diet.
Cicadoidea
cicadas
Cicadoidea is a superfamily of insects in the order Hemiptera, suborder Auchenorrhyncha. It comprises two families: Tettigarctidae, containing two species restricted to Australia, and Cicadidae, with more than 1,300 described species worldwide. Cicadas are characterized by their large size, bulging compound eyes, short antennae, and distinctive acoustic signals produced by males. The superfamily includes both annual and periodical species, with the latter exhibiting remarkable synchronized emergences after 13 or 17 years of subterranean development.
Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.
