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 spit bugs, and their froth as cuckoo 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.
The froth serves a number of purposes. It hides the nymph from the view of predators and parasites, it insulates against heat and cold, thus providing thermal control and also moisture control. Without the froth the bug would quickly dry up. The nymphs pierce plants and suck
sap causing damage, and much of the excess filtered fluids go into the production of the froth. A few species are serious
agricultural pests.
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 4000 m/s^2 over 2mm as it jumps. Many species resemble
leafhoppers, but can be distinguished by the possession of only a few stout spines on the
hind tibia, where leafhoppers have a series of small spines.
