Delphacidae

Delphacidae is a family of planthoppers containing about 2000 species, distributed worldwide. Delphacids are separated from other "hoppers" by the prominent spur on the tibia of the hindleg.

Diet and Pest species
All species are phytophagous, many occurring on various grasses. Some species are significant pests and important vectors for cereal pathogens; for example:
 * The rice brown planthopper, Nilaparvata lugens (Stål)
 * The white-backed planthopper (rice), Sogatella furcifera (Horváth, 1899)
 * The sugarcane planthopper, Perkinsiella saccharicida Kirkaldy, 1903
