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 ...

They are sometimes called tube-forming spittle-bugs as the nymphs form a calcareous tube within which they live. These bugs are mainly found in the Old World tropics. The adults of many genera have a long, free and spine-like process originating from the scutellum and thus superficially similar to the tree-hoppers, Membracidae.

Cercopidae are the largest family of Cercopoidea, a xylem-feeding insect group, commonly called froghoppers. [2] They belong to the hemipteran suborder Auchenorrhyncha.A 2023 phylogenetic study of the family suggested the elevation of the New World subfamily Ischnorhininae to full family status as Ischnorhinidae, leaving a monophyletic Old World Cercopinae.
