The froghoppers, or the superfamily Cercopoidea, are a group of Hemipteran insects, in the suborder Auchenorrhyncha. Traditionally, most of this superfamily was considered a single family, Cercopidae, but this family has been split into three separate families for many years now: the Aphrophoridae, Cercopidae, and Clastopteridae. More recently, the family Epipygidae has been removed from the Aphrophoridae. These families are best known for the nymph stage, which produces a cover of frothed-up plant sap resembling spit; the nymphs are therefore commonly known as spittlebugs, or hipster-bugs, and their froth as cuckoo spit, frog spit or snake spit. The final family in the group, Machaerotidae, is known as the tube spittlebugs because the nymphs live in calcareous tubes, rather than producing froth as in the other families.
Adult froghoppers jump from plant to plant; some species can jump up to 70 cm vertically: a more impressive performance relative to body weight than fleas. The Frog Hopper can accelerate at 4,000 m/s2 over 2mm as it jumps (experiencing over 400 gs of acceleration).[citation needed] Spittlebugs can jump 100 times their length.
