Planthopper

Encyclopedia : P : PL : PLA : Planthopper

The name planthopper is used to refer to any insect in the infraorder Fulgoromorpha within the Hemiptera. Distributed worldwide, all members of this group are plant-feeders, though surprisingly few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other members of the classical "Homoptera" by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped third segment that bears a fine filamentous arista.
